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

User Experience:

Hello Sue and Richard,

I want to take a moment and thank you for building wonderful sounding and beautifully built 300B mono amplifiers! We manufacture a high sensitivity line source loudspeaker system (Arion Audio Apollo System) and needed high quality mono amplifiers for our showroom. After doing our research we chose the Sophia Electric 91-01 Signature 300B Single Ended mono amplifiers.

I purchased the pair of your Sophia Electric 91-01 Signature 300B SE mono amplifiers about six month ago and couldn’t be happier with their performance. The sound and performance of the main system in our showroom which includes our new Arion Audio Apollo speaker system and the Sophia Electric 91-01 Signature 300B SE mono amplifiers have impressed everyone who has heard it. The system sounds powerful, yet detailed and delicate. The amplifiers have impressive high frequency extension but never sound harsh or piercing. The ever-so-important low midrange / upper bass is well articulated and musical. It’s easy to follow bass lines. We will enjoy our pair of Sophia Electric 91-01 Signature 300Bs for many years to come.

I must add that working with both Sue and Richard has been a great experience. Thanks!
