I want to start out by saying that I am very content with the NOS Sylvania
6SN7GTB's 1960 tubes in my Modwright Oppo 83. There was a couple posts over on the Audiogon forum that got my curiosity about the Sophia Electric tubes. These are new production tubes and have a coke bottle shape. They also offer three classes of this tube, which I thought was odd. They offer Class A, B and C ($100, $75 and $50 each). I decided to order a class A matched pair of these tubes and they arrived today.

So these are my initial impressions. This tube takes 300 hr. to fully break in. Right out of the box, I could tell these were something special. These are NOT euphonic tubes. They are totally neutral and linear. There is a slight increase in resolution from what I'm used to hearing. What strikes me most though is the wider soundstage and music sounds more 3D. There is also more separation between instruments. On the down side, there is a slight tilt towards the treble. This is subtle but noticeable. Reviews say this is normal and that it balances out as it breaks in. Bass is tight and extended.

I'm sold on these Sophia Electric 6SN7 tubes. :biggrin: Check out this review I found on them: http://www.avguide.com/blog/giant-killers-new-tubes-sophia-electric

I'll give an update after they are totally broken in.

    What other 6SN7 tubes have you compared the Sophia's to?

    I have watched the marketer's do what they do to fully exploit the vacumm tube resurgence into more mainstream audio enthusiast products. There are differences in tubes, however, this 100 percent mark-up in identical tubes seems over the top to me.

    Thanks for the review Ern and glad you are digging the gear.

    I've rolled in about a handful of different 6SN7 tubes into my Oppo. I found the nos Sylvania GTB's to have the best synergy with my rig- that is until yesterday.

    I am interested in trying out the Shuguang Treasures CV181's and hearing how those compare.

    Life is too short to not have great sounding tubes.

    100+ hours break-in update: Well that tilt toward the treble is gone now. It sounds warmer now. There is noticeably more bass too.
