User Feedback for S.E.T. Princess™ 300B Carbon Plate Tubes - from Decio, Brazil (February 2007)

Dear Richard,

I had in my life, a good number of speakers and amplifiers (both, tube and transistor), but I fell in love instantly, as never before, with my first Avantgarde Acoustic, a UNO ... I was already in my second one, a DUO (much better) when a friend came to demonstrate his Audio Note Conqueror, which I ended up buying from him (it had several goodies, as Black Gate capacitors, etc; he was going to a newer Audio Note version). Initially I was skeptical if a mere 8 watts would be able to drive them, but it worked...

And now, with the Sophia Electric S.E.T. Princess carbon plate 300B tubes, the sound is simply incredible. It has all the "beauty" and "clarity" that only a 300B single-ended amp is able to show, but ALSO the best qualities, that are usually associated with the best transistorized amps., like SPEED, and a correct and defined low frequency, that goes VERY deep!!!... (Actually I don't remember hearing such a good bass, from ANY amp)

Note that I am comparing the Sophia Electric S.E.T. Princess carbon plate 300B tubes to the much acclaimed "Western Electric". These don't come close. They don't have the speed or the bass in the same category… With the Sophia Electric S.E.T. Princess carbon plate 300B tubes, you have everything, the "complete sound package". Nothing is missing…

I would like to congratulate you for a magnificent product: The "State of the Art", Sophia Electric S.E.T. Princess carbon plate 300B tubes!!! It couldn't be any better.

Best regards,

Decio
