Coming soon... 'PGGB Reference Systems'
With PGGB V9, a new kind of listening setup comes into view: PGGB’s high-precision reconstruction and noise shaping can be integrated with live playback from a source player to a DAC. For listeners who value what PGGB processing can bring to a system, this opens up intriguing possibilities. In this approach, PGGB handles much of the upsampling and signal processing before the signal reaches the DAC. The DAC’s role is then focused on converting the incoming upsampled signal to the final analogue output. That may make it possible to build... Read more...
PGGB V9 — Precision Optimized Engine and New Capabilities
PGGB V9 introduces the Precision Optimized Upsampling Engine as the new default (the previous Nyquist-Shannon engine remains available for offline whole-track processing). This is not a minor optimization; it is a reformulation of the reconstruction approach that changes both the quality ceiling and the practical resource requirements. How the New Engine Works The Precision Optimized engine builds a processing pipeline tailored to the selected precision and the exact input-to-output sample-rate conversion. Within the passband it preserves, reconstruction accuracy is limited by the arithmetic precision (up to 256-bit) rather than by... Read more...
PGGB V9 — The Biggest Change Since PGGB Began
PGGB has always been about one core idea: take the heavy lifting of high-accuracy reconstruction out of the DAC and do it better, earlier, with far more precision than hardware can manage in real time. Until now, that meant offline remastering — process your files once, then play the result in your preferred player. PGGB V9 is the largest evolution of the technology since it began. It keeps the complete offline remastering workflow you already know and adds the ability to hear the same high-precision processing Live while you listen.... Read more...
OPTO•DX on Batteries - A Testimonial
My OPTO•DX customers will often ask for a power-supply recommendation. OPTO•DX requires nominal DC 12V (11V - 15V acceptable) at ~ 200mA so most audiophiles already have a compatible linear supply they can use. For customers who wish to purchase new, they usually ask my opinion of iFi Power ...and these work but, beware, they use switching technology. In general I say use well conditioned AC mains and a separate supply for TX and RX.  When a customer, like David in this post, wants the absolute best sound from OPTO•DX, my ultimate recommendation...

PGGB•IT! + Azure Testimonial
Thanks to Ruud L., Amsterdam for this Testimonial I was always finetuning and looking to get the best out of my audio chain hardware. Sometimes software can help you to accomplish an upgrade in the audio experience. So I seriously investigated upsampling and the discussion to upsample or not; to let the streamer or the DAC upsample; to let the software player upsample. A tried them all. Then I got a new DAC capable at doing native DSD512 in pure NOS. So i started to download native DSD DXD recordings.... Read more...
PGGB V8: A Monumental Leap Forward!
PGGB’s continuing evolution in uncovering every hidden detail in your audio recordings has just taken a massive leap with Version 8 (V8). Since launching in 2021, PGGB has stayed relentlessly focused on one unbreakable rule: quality above everything else. The PGGB algorithm has always hovered at the edge of technical perfection — and V8 pushes it even closer while delivering real, jaw-dropping performance gains: Speed Revolution — Full power of CPU Advanced Vector Extensions (AVX) delivers up to a staggering 4× speedup. This isn’t a small bump — it’s a total... Read more...
WaveTheory Discusses PGGB vs HQP
YouTube audio podcaster WaveTheory just completed a four-part series discussing software upsampling; specifically comparing PGGB and HQP. I applaud his fair treatment of this complex topic. Enjoy! Read more...
PGGB•IT! Azure Integration for (Legal) High Power Upsampling
The upcoming (March) release of PGGB•IT! adds version-wide support for offloading PGGB processing to Azure compute instances. This lets you leverage scalable high-core virtual machines (VMs) with lots of RAM through your own Azure account—no queues, no shared servers, just on-demand upsampling power. The workflow stays fully under your control using the same familiar PGGB•IT! interface. Select your source files, connect to your selected VM and PGGB•IT! automatically uploads your content, runs the processing remotely on the VM, and downloads the upsampled files back to your local drive.  PGGB•IT! with...

OPTO•DX Customer adds SRC-DX to M-Scaler BNC Input
Thanks to Daniel G., USA for his Testimonial My journey with AudioWise has been an exercise in discovering additional depth and layers of sound within a system that at each stage was fully satisfying before each add.  First was adding OPTO-DX and DC-BLOCK between M-Scaler and Dave. The change was immediately noticeable: an equivalent uptick in SQ as when I originally added M-Scaler. Optical isolation was for real: adding more depth and weight to the sound, and more precise imaging.   Most recently, and more on a whim given the... Read more...
Consider the Astell & Kern SP3000M for your SecondaryPrimary Sound System
Many audiophiles have multiple sound systems, each in its own listening space. The primary system is for critical listening, typically loudspeaker-based in a dedicated room, while the secondary system is for more casual listening, perhaps bookshelf speakers in an office or common room. Sometimes the primary system is an elaborate analog rig, while the secondary system is a simpler digital setup. Conversely, the primary system might be high-end digital, and the secondary system, tabletop digital. Ultimately, the choice is determined by budget, available space, and individual listening preferences. Headphone systems... Read more...
2026 — The Year DSD2048 Finally Drops!
With the recent launch of the Gustard U26 DDC, playback of DSD2048 is now possible to high quality DACs. As I have mentioned in previous blogs, a DSD512 bitstream to a Holo Cyan2 (via USB) is tops for transparency...low distortion and amazing detail. DSD1024 (via USB) improves the level of detail but also increases distortion. Using the Gustard U26 and I2S protocol, a DSD2048 bitstream functionality is possible to Cyan2 but consider Leung H.'s post for sound quality. I will need to invest in a May! Thanks to Leung H.,...

Why DSD-to-Analog Playback Can Provide the Best Sound
Digital audio production uses PCM for unsurpassed quality and flexibility for recording and editing. 32-bit floating point PCM at 192kHz sampling offers high resolution and unlimited headroom. The process is essentially all signal processing mathematics using a high resolution DSP or software to provide ultra low digital noise. The predominant mastering format is PCM: CD (16/44.1) or streaming (24/96). For mastering to high resolution PCM downloads, sampling up to DXD (352.8) is available for audiophiles to make use of their high end PCM DACs. Similarly for mastering to DSD, sampling...

DSD vs PCM vs Cyan2 vs Mojo2
For several years, now, I have been presenting at trade shows using Chord product and PCM content. I've been a Chord fanboy since before Dave was launched. Rob Watts always impressed me with his digital expertise. Back in the day, I felt that Dave and MScaler was the penultimate combo but I discovered that all Chord DACs could be moved toward that level of transparency using AudioWise RF noise isolation and PGGB upsampling. So my daily listen for PCM evolved to a Mojo2 (tricked out as per my Reference/M2 setup).... Read more...
OPTO•DX Testimonial : Building a MScaler/TT2 Endgame
OPTO•DX was launched in 2019 just as the MScaler was beginning to grow in sales. The goal was to optically isolate the Dave DAC from upstream MScaler conducted RF noise ...which is detrimental to transparency. MScaler produces large amounts of wideband RF noise that conducts via signal, power or radiates across free-air. By using an optical "air-gap" OPTO•DX helps to eliminate much of this noise. Compared to other solutions like filtered BNC cables or ad-hoc digital tweaks, OPTO•DX is the pragmatic choice: the technically superior solution for the knowledgeable audiophile.... Read more...
Can Grok/ChatGPT help us get smarter about Audio?
With the advent of AI engines such as Grok or ChatGPT, LLMs (large language models) are well trained on all human knowledge, including about audio, I've been using Grok lately to help with software development and content marketing. When I query Grok about audio I get answers that are, for the most part, technically sound, however AI understands the mechanisms for audio involved in the analog domain, but in the digital domain it still does not understand what is going on and mainly provides only general suggestions. For example, in... Read more...
A Commentary on our Ear/Brain Sensitivity
Here are a few news stories that recently crossed my desk...all related to how the industry is acknowledging and addressing the incredible resolving power of the ear/brain. The audio news forum Headphonesty published an article regarding the perplexing differences in sound between CD players. Its worth a read...we've all had the similar experiences of markedly different sound while tweaking our signal chain. The author, after much research and analysis of the testing, determined that the small (1.7dB) discrepancy in output volume between players likely accounted for the subjective difference ...as...

A Testimonial for PGGB•IT! PLUS
Thanks to Michael M., USA I'm using a Gustard R26 DAC with an Aurender N100H., which is too low powered to be practical for real-time use with HQPlayer, so I investigated PGGB•IT! to give me options. I knew someone who used PGGB and they claimed the more extensive/better oversampling was like magic. My understanding is that there are advantages to pre-converting the file rather than real time, because it can do a better job and reduces the work of the player. My upgrade to PGGB•IT! PLUS ran on my 16GB... Read more...
PGGB+TS for Analog Tape Recording
Reel-to-reel 1/4" analog tape remains a niche format cherished by nostalgic audiophiles. Although tape machines have largely been out of production for decades, Revox recently launched the redesigned B99 MKIII, and the used market thrives with high-quality machines readily available. Professional recording studios often maintain these machines, ensuring a steady supply of parts and skilled service technicians. For those interested, Studer, Otari, and Revox are top choices for quality and parts availability, followed by Technics, Teac, Akai, and other Japanese brands. In late 2024, I acquired an Otari MX-5050 to... Read more...
PGGB•IT! MAX Now Supports Processing on Azure Virtual Machines
For PGGB•IT! power users who remaster the longest tracks to the highest quality, the issue has always been to accommodate the processing within the constraints of their system RAM. PGGB•IT! has various options to get around this: A)  Check ☐ Force 1Ch to process Left then Right in separate passes. B)  Increase the amount of disk mapped virtual memory and use ☐ Optimize PCM Paging C)  Check ☐ Input Block Processing to use shorter duration blocks D)  Use lower precision (for PCM) or use a lower modulator order or stage...

Holo Cyan2 with PGGB @ DSD512₄₈ is Magical
I have been a long time fan of Chord Electronics and the bulk of my orders are to Chord customers. I do provide a range of isolation solutions for all their DACs and, if you've been following me, my current Chord DAC in hand is the Mojo2. It became my favorite DAC with the addition of my signal & power RF isolation kit. Many users adopted my approach, but for some, the extreme measures were a distraction from just buying a DAC that performs at its best out of the... Read more...
USB DAC Isolation (feat. Holo Cyan2!)
There are a growing number of DACs in the marketplace: affordable and competent and mainly Chinese: Topping, S.M.S.L, Gustard, Denafrips, Holo Audio etc. My REFERENCE•M2 system uses Chord Electronics Mojo2 for its unbeatable performance, 5VDC power - and affordability. For REFERENCE•M2/DX I utilize DBNC (dual BNC) from SRC-DX to the Mojo2 but the digital signal from SOURCE to SRC-DX relies on USB transport. Fundamental to this are my products: OPTO•USB, USB•FILTER and my shielded USB cable with ferrites. Note that USB•FILTER is has native USB-C connections but has full compatibility... Read more...
The Incredible RF•STOP SE Signal Filter
My product development iteration involves improving my output chain as I reveal more transparency at the DAC and upstream. So when a change is made I need to be able to hear the tangible benefits on sound quality. Currently, this is what I have: Analog output from Mojo2 (3.5mm to Stereo RCA) goes into an RF•STOP SE Signal Filter (EXTREME variant) to a Benchmark HPA4 amp and then to HE1000se headphones. As I presented in my blog posts here and here, RF•STOP Signal Filter is a blocking filter that prevents... Read more...
REFERENCE•M2 System - January 2025 Update (Revised)
I have updated my REFERENCE•M2 Systems. I want to emphasize the following updates: USB and DX (DBNC) Version. The DX (DBNC) version is now complemented with a USB version (here) which leverages USB-C Filter, RF•STOP SE Signal Filter x2 (below) and the amazing benefits of PURE•DC power on the Mojo2 USB signal path. The USB version has more discernable digital hash than DBNC despite the increase in resolution to 32-bits (USB) from 24-bits (SPDIF). After many listening tests, I am comfortable to say that the more expensive DX version is still... Read more...
PGGB-RT for foobar2000 - New Release!
PGGB-RT for foobar2000 has been updated to PGGB v7 core technology and has been overhauled to support 64-bit foobar plus improve performance and stability. Notable changes related to sound quality are the addition of 107-bit precision, 4M samples (Speed) mode and lossless EQ (convolution, parametric or a fixed 4-band): PGGB-RT's stream renderer architecture within foobar allows for a longer look-ahead window of track samples to be processed. At 107-bit precision this offers unmatched reconstruction accuracy compared to competitive foobar components (DSP, sample-rate-converter, etc.). Quality mode utilizes all samples in a... Read more...
PGGB+REFERENCE•M2 = Digital to Analog Nirvana?
The consensus among audiophiles, who are invested in both analog (vinyl or tape) and digital (CD’s or digital downloads), is that analog provides the ultimate listening experience. Although analog has lower resolution and higher distortion than the technically superior digital, audiophile dollars are being spent on analog’s antiquated technology because it ‘sounds’ better. This is the core mystery: why does the physical process of modulating grooves in vinyl or magnetic flux on tape directly to analog provide a more pleasing listening experience than the more theoretically exact reconstruction of analog...

Toronto AudioFest Testimonial
Thanks to R. Lee for his posted comments (transcribed from this Head-Fi Post ) Audiowise RF Isolation SystemLet me start by saying that the sound coming out of this system is nothing short of stunning. This setup is hard to describe, as there's a complex chain of connections that will make your head spin, but basically starts with its PGGB unit performing offline upsampling (floating point DSP, 24/768 conversion) to the Chord Mojo2 DAC while fed by a carefully isolated power supply, housed in an RF-STOP Faraday Isolation Box that shields its audio components from...

How I Transformed Mojo2 into a Reference DAC (Part 3)
This blog post (final in the series) describes the component layout inside RF•STOP Faraday Box. The picture above is my layout for the Toronto Audiofest. As you can see there is plenty of interior space for cable loops and component configuration options. For final production/shipping Reference systems, I will suggest a few layouts (which, BTW, will support Mojo2 or QUTEST!). For the show, I have installed plexiglass risers to better present the Mojo2 when visitors peek inside (of course RF•STOP Faraday Box is closed during normal operation). Here is a breakdown of the...

How I Transformed Mojo2 into a Reference DAC (Part 2)
I developed RF-STOP Faraday Isolation Box in 2019 after determining that using OPTO-DX to optically isolate DAVE from MSCALER was only part of the total isolation solution. RF noise was impinging on DAVE via powerline conduction (AC mains, in-wall & cables), and via open air radiation (up to 5 meters!). I researched and wrote a whitepaper here. Its dated but still worth a read-through. RF-STOP Faraday Isolation Box was custom developed for me by a well regarded supplier to the mobile phone industry (testing and FCC/CE compliance). I specified rugged welded aluminum... Read more...
Prepare to be Amazed by REFERENCE Mojo2 at Toronto AudioFest
AudioWise will be exhibiting at EARVANA - part of the Toronto AudioFest. EARVANA is a 8000sqft dedicated headphones-only exhibit space where I will be showcasing my REFERENCE Mojo2 system. I will have two listener positions (separate amp/headphones) - or bring your own rig (TRS/RCA connections). Musical performances will come to life with astonishing transparency and intimacy. I guarantee the finest sound reproduction you will hear at the show.  Read more...
How I Transformed Mojo2 into a Reference DAC (Part 1)
Mojo2 has been winning awards and accolades since its launch. At a street price of $500, it is a hi-fi bargain that has allowed the audiophile masses to experience a taste of 'transparency': that strong sense of reality creation which, IMO, is essential for full enjoyment of music. For over 10 years I have been at the forefront of understanding how to improve a DACs transparency through isolation of RF noise. In that pursuit, several brands of DACs have crossed my desk but those from Chord Electronics, IMO are without... Read more...
PGGB•IT! PLUS Testimonial
Thanks to Bruce C., Georgia, USA I purchased PGGB•IT! in June 2024 and consider it a bargain. It actually works as advertised and is well worth the price if you listen to music as a primary activity as I do. I ordered the 'PLUS' version to try PCM and DSD on my various DACs. I have been PGGB processing my music collection a bit at a time. It opens up both older and newer music noticeably. I see the higher sampling rate and bit depth in the larger file sizes and audibly... Read more...
DSD vs PCM 24/32 Comparison with Mojo2 (Part 2)
My testing for this comparison was using my REFERENCE Mojo2 system. Mojo2, like all Rob Watt's DAC design, has an internal PCM signal path. Note that Mojo2 uses a 104-bit DSP design vs the 64-bit DSP in other chord DACs. This will provide it an advantage in digital signal processing. With regard to DSD. DSD input is converted to PCM and this, according to Mr. Watts, results in distortion. However I thought that DSD sounded great. So any distortion was i) imperceptible to my ears through my headphones, ii) beyond the... Read more...
DSD vs PCM 24/32 Comparison with Mojo2 (Part 1)
I have been working on a new reference based exclusively on the Mojo2 DAC in combination with PURE•DC 5V power inside a RF•STOP Faraday Box. I use optical signal transport from my source (Windows laptop) and RF•STOP Signal SE filtering to headphones. PCM 16fS was to be my exclusive test stream but the recent release of PGGB 6.0 with DSD mastering has created quite a stir on forums and I decided to do a proper DSD/PCM comparison. And while I was at it, I decided to test if PCM 24-bit vs... Read more...

PGGB•IT! Precision Elevates DSD Sound Quality!
The high accuracy core of PGGB•IT! enables it to achieve PCM reconstruction quality that is arguably the best that is available today. And soon, with Version 6, the same high accuracy reconstruction will make DSD shine. The word from early users is that DSD sound quality is beyond what they have ever heard before. PGGB•IT! is an offline process and although its algorithms are resource intensive, the effort all but eliminates the high quantization noise that is generally associated with DSD's 1-bit format. PGGB•IT! reimagines DSD with conversion up to DSD1024; 9th... Read more...
PURE•DC Perfect Power: Zero Noise and Ultra-low Impedance
Recently, I have been enamored with the Mojo2 - for its affordability and ability to be transformed using my kit of products. I have addressed isolation from RF noise on signal (SRC-DX chain with RF-STOP Signal), radiated (DAC-WRAP and environmental) and suggestions for power. Mojo2 has an excellent, low-noise internal battery design but users have reported sonic improvements with external 5VDC power - which required disconnection of the battery to force Mojo2 into desktop mode. As my readers know, LFP batteries rule in my system: they have near zero electrochemical... Read more...
Audio Nirvana Redux
Thanks to Vitaly R., New Hampshire, USA for this testimonial! Dan is not an ordinary vendor, I consider him an integral part of my audiophile journey. I started evaluating Audiowise’s products with a healthy dose of skepticism. My basic assumption was that a high-end product, be it a DAC, streamer or any other part of the signal path, is designed to be immune to any conducted or radiated source of interference. Well, that assumption turned out to be false. With Dan’s help, I learned to appreciate the importance of RF hygiene... Read more...
Audio Bacon Reviews PGGB!

SRC•DX Celebrates Its Four Year Anniversary!
The arrival of the Chord Electronics MScaler in 2018 heralded the beginning of a revolution in digital audio. Rob Watts showed the world that better signal reconstruction was possible through extreme application of the theoretical. Improvement in signal accuracy (no matter how small) was audible and a wider 'Sinc' filter (more taps) benefitted transparency and staging. MScaler also cemented the role of Dual-BNC (DBNC or DX) as being Chord's internal interface: two streams of digital coax (SPDIF) using a 'dual data rate' (AES) protocol to support up to 768kHz sample rates. This... Read more...
Extreme Upsampling Blu-Ray with Topaz Labs & PGGB
Thanks to Alex L., New York City, for providing an informative summary! My passion is watching Blu-Ray movies and I have a large collection stored on my server. Yes I have ripped the discs using 3rd party software tools but I own originals of all my content, so I've done this for convenience. My playback is from a Windows system to an AV receiver using HDMI 2.1 transport. My TV did an 'okay' job upsampling video but for the utmost in quality, I use Topaz Labs Video AI to software pre-process 1080p/24... Read more...
PGGB•IT! Integrates a 4-Band EQ
PGGB•IT! already supports EQ using the import capability built into Remastero PGGB (using the PGGB-EQ tab). In this case, a measurement file is imported into PGGB_EQ and converted to a high precision internal format for use in PGGB•IT!. The imported file (convolution wav) requires a microphone and external program, like REW, to adjust for loudspeaker/headphone frequency response or to accommodate room correction. Alternatively, a file (parametric txt) can be sourced from a database of measurements or manually created using RoomEQ or AutoEQ. While this method allows for absolute equalization control, its somewhat complicated for ad-hoc... Read more...
A Pragmatic User Finds AudioWise (and Mojo2!)
Thanks to Nikhil O. of Brooklyn New York for this testimonial! When it comes to my headphone listening, I focused on maximum musical enjoyment per dollar spent. Guided by extensive forum research, I chose products from Gustard, Topping, and headhones from Drop. Forum discussions praised the benefits of upsampling, so I experimented with HQPlayer and PGGB-RT, experiencing subtle changes that didn't align with others' significant improvements. Suspecting issues with my power and digital delivery, I invested in a separate network endpoint, power conditioners, and grounding boxes. Despite some improvement, I... Read more...

Mojo2 with Amplification
When driving Mojo2 to my PMC MB2S studio loudspeakers, I tested a variety of amplifiers. Overall, I'm incredibly happy with my class AB Accustic Arts Mono-II's - both direct from Mojo2 or through my companion Preamp-II Mk2. However, I wanted to broaden my recommendations for more affordability and customer choice, so I tested class A (Allnic Audio), class D (AGD Productions) and various solid state class AB. All were 100W or more - sufficient to be able to drive my PMCs.  Mojo2 direct to headphones is the GOAT (Greatest of All Transparency) and... Read more...
Mojo2 Magic in Four Easy Steps
Here you go. These steps essentially reproduce and explain my setup at the Toronto Audiofest as described here to get you endgame transparency. I know my ears but I hope to solicit owners of high end DACs to corroborate. Since the effects of RF/EM noise are cumulative (interference of frequencies), application of substantially all recommendations is where you hear the most benefit - but you can certainly take it step by step as your budget allows. #1 Input Use a low noise source. I personally use a modern Windows laptop (Lenovo) with... Read more...
Magic for the Masses
If you have been following my posts about Mojo2 but are still skeptical that it can be the basis for the best DAC... then this is not for you; or if you prefer subjectivity in sound over the absolute, you can stop here; or if you wish to remain spellbound by the pervasive misunderstandings about digital audio then, again, please move on. When I started AudioWise in 2016, I heard hints of 'magic' transparency in high end systems and I became obsessed with wanting to understand it and I explored means to recreate... Read more...
Mojo2 at Toronto Audiofest
At the most recent Toronto Audiofest Show, I had a stand displaying both Dave and Mojo2 systems. The Dave setup was not powered: just a show 'n tell mockup of isolated signal and power using my kit and battery power. The Mojo2, however, was live for headphone listening as per the attached drawing and pricing. My stand was busy and the response was very good; look for press and media coverage to provide show reports. In this blog, specific to the Mojo2 setup, I will convey what I recall of... Read more...
Breaking the Spell: An Audiophile’s Testimonial
Thanks to Evan S., Boston USA for this amazing testimonial! When I first contacted Dan at AudioWise 3 years ago I was running Chord Electronics Hugo TT2 + MScaler and my source was an UltraRendu+Roon playing local (FLAC) and streamed content. My speakers were ATC SCM40A (active) and everything was on well conditioned AC power with a full loom of high end cables by Synergistic Research to the tune of $75k. I was quite pleased with my system, but always looking for ways to further improve the sound. So I... Read more...
