Pure Class A and Single Ended Triode with zero feedback design, for the ultimate in lush musicality, but are surprisingly dynamic when playing large orchestral pieces.  The Bass Drum in a dynamic performance is wonderful.  The impact on the drum, the vibration of the skin and the echo from the back of the room are what music is all about. These are great amplifiers and a perfect ultra musical amplifier for the discerning listener. They have power, authority and bass control out of all proportion to the relatively modest rated 28 watts per channel.

They are not designed for inefficient speakers or people who want to play heavy rock, or big drums at a high level, but they have a delicacy, transparency and natural musicality found in few amplifiers. Vocals are smooth and rich, amongst a huge, open soundstage. These are a top seller, and no wonder.

 

A face mounted bias meter for easier monitoring. Flat black finish.
