User Experience on Sophia Electric 91-01 300B Signature Mono Block Amplifiers

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!
