The MP-301 series is the most popular Musical Paradise tube amp since it was first released in 2008. The Mk2 was introduced in 2011 with many improvements and the most recent Mk3 continues the ongoing enhancement process to bring the MP-301 series to a new high performance level.
The MP-301 ships with standard tubes. Optional tubes are strongly recommended in this excellent review here.
