Sophia Electric’s Richard Wugang redesigned/modified 91-03 stereo amplifier and made the 91-01 in steel chassis for those who wanted for mono-block and at lower budget. The standard version was an instant hit in the market place. Read Jeff Day's Review below:
Positive Feedback Review: "The Sophia Electric Model 91-01 300B mono amps are audiophile dream amps, they have great sonics top to bottom, bass articulation that is the best I've heard, and the SE 91-01 nails all of the nerdy audiophile things like soundstaging, imaging, sense of space, and transparency in such a beguiling way that even music lovers that don't give a rat's ass about audiophile-type sonics will appreciate its prowess.
I recommend these amps heartily, and I'd give them my normal 'two thumbs up' endorsement, but that just wouldn't capture what these Sophia Electric Model 91-01 300B mono amps are capable of, so I've invented a new rating, the 'two hard nipples up' recommendation, which is the highest award I've given out to date." ––– Jeff Day
