User Feedback for Sophia Electric™ 6SN7 Tubes - By George from Chicago, IL (July 2009)

Dear Sophia Electric,

I own a Viva Solista 845 tube amplifier that uses 6SN7 tubes as driver. I ordered two 6SN7 tubes from you ten days ago.

My first reaction to these coke bottle 6SN7 tubes was positive. Looked at the workmanship, brass base and gold pins, it was quality in detail.

I have owned several NOS top brand 6SN7 tubes: Sylvania and RCA, etc. After I bought Solista 845 amp, I even pursued to get a pair of the highly regarded and high rated NOS Sylvania 6SN7 from a dealer’s private stock. It was the best I have heard at that time.

However, when I plugged in this new Sophia Electric 6SN7 tubes, immediately, the sound stage opened up, the sound became fuller and the drive capability to my 845 amplifier became much more improved.

After ten days (about 30-40 hours later), it is even better. Now I can conclude these Sophia Electric 6SN7 tubes are clearly better than the NOS Sylvania and RCA 6SN7 tubes I have been played with. The soundstage is so much larger, I can pin point the instrument on stage. I feel as if I was there. It is 3-dimensional and it is sensational! This is one of the biggest upgrades in sound in my system.

Anyone who own tube equipment requiring 6SN7 tubes, definitely should try these incredible Sophia Electric 6SN7 tubes. They owe themselves to hear the very best 6SN7 from Sophia Electric.
