IMPRESSIONS OF DAN's REFERENCE SYSTEM

An incredibly high ceiling and sense of space without any noise or hiss. Everything sounds so smooth and supple ...no harshness or fatigue at all.  The individuality and nuances of instruments and vocals are quite identifiable.

Nicki N, Canada. Singer/Songwriter, Sound Engineer

The music sounded as pure as a live studio experience ...truly present and immersive with incredible detail and dynamic range. If sound was water, it soaks you wet.

Steven J, Canada. Music Teacher (Strings, Vocals)

The sense of space created was unique to my recorded listening experience. I could hear exactly what instruments were in what position and with excellent timbre. The impression was of a live performance ...a wall of music would engulf me and I would listen to the little intricacies as I never have before.

Michael K, Canada. Classically Trained Pianist

This is silky smooth conversion with crystal clear transients and spatial cues. Sounds like the bass amp is in the room! I find myself fully enjoying the music while also able to easily discern the mix effects and recording techniques used. Nice shit! This is as good as I have heard.

Mike B, Canada. Sound Engineer, MuchMusic, CityTV (Toronto)

OPTO•DX User Testimonials

When it comes to isolating your digital chain from your analog chain, there is nothing better than an optical air gap.

Ray G, USA

Timbre and transients are off the charts. I'm picking up ambience that I never did before. OPTO•DX is un-muffling the f*ck out of the music. It certainly feels endgame.

Michael D, UK

The best way to eliminate the RFI issue completely is with OPTO•DX. It is one of the most significant upgrades that I have ever made to my Hi-Fi system.

Neil VM, Ireland

...much larger soundstage, better separation, better dynamics, more vivid sound ...it's the best I've heard my system.

Bernard H, Austria

...the reduction in noise is profound. I’ve never heard a background this black. I honestly can’t believe the sound coming from my speakers

Ken B, USA

I find it's just so easy to listen...lots going on in 3D too...the sound from OPTO•DX is pretty astounding!

Alfie M, Canada

OPTO•DX is a fantastic product...more depth and holographic representation of the music. I have truly never heard such good sound.

Steve A, Australia

OPTO•DX is lifting up my system very nicely. The degree to which I can hear the benefits on instrument resolution is striking.

Cedric W, UK

It was really hard for me to believe that there was still that much more information being blurred by RF noise. The optical isolation of OPTO•DX just takes things to a whole different level
