User Feedback for Sophia Electric™ 45 Mesh Plate Tubes - By Mr. Yannick Mahé, France (May 2005)

I listened Sophia Electric 45 triode on my own system ( 97dB 420A + Ribbon supertweeter on a massive maple open baffle ).

I also listened them on a friend big 116dB horn system. ( with a Supravox field coil 15 inch woofer with an hybrid power amp for the bass ).

Both 2A3 and 45 amplifiers have transfo coupling, Black-Gate capacitors and high quality output trans.

We compared them to several 2A3 and 45 tubes.

The Sophia’s is clearly the best. Power increases subjectively, even in comparison with 2A3. Amazing! Better balance, definition, soundstage, dynamics, sweetness (everything, in fact)...something like true.

"organic realness" said Dr. Gabbard. I totally agree!!

Perhaps the best tube I ever heard.
