Sophia Electric 91-05 300B Dual-Mono Stereo Tube Amplifier

 Sophia Electric 91-01 vs. 91-03 vs. 91-05 300B Single Ended Amplifiers  User Reviews 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 Sonic Purity * Super Quietness * Sonic Magic and Musicality  Sophia Electric's competitive advantages come from superior propriety output t
