  1. The most musical tube is the Tung Sol 6SN7GT round plate. It's simply the best balance of everything a tube can offer , what else can I say? Exquisite detail, strong bass, glorious midrange and extended highs ,thank you Koray for these RARE JEWELS.

  2. Alkis Papadas, i don't think i could describe the wonders of this glorious tube better than yourself.

    Thank you Koray, it's surely a delight to listen to. I think i'll buy another and keep it as a spare.

  3. I just received mine! Excellent tubes, after so many years, they are still in such good conditions. Tubes made in their prime years! I use a pair on my wooaudio wa22 and wa5 headphone amp. Sonic quality excellent.

  4. These tubes are something else. They are highly musical and they add enormous detail to the music. Have I mentioned the detail they brought? Can't mention enough..

  5. I just received the Tung Sol Black Glass Round 6SN7GT today and even without them broken in yet, they sound fantastic.

    I also want to say what a great experience it was working with Koray. All emails were replied too immediately, shipment was made the day that he received payment, and I received them two days later in the U.S.
