Very recently took delivery of a single ended pentode Class A, a Ming Da Piccolo Mk2.
It is an integrated amp with selector and remote control volume, KT90 output operating in ultralinear.
It has already been upgraded with Audyn coupling capacitors by Mark at Ming Da UK and sounds very good.
However it now sounds spectacular after fitting direct input sockets and completely bypassing the cheap volume control.
I am extremely pleased with the performance into my Quad ESL57's, it's a great match.
