Tube Rolling for TAD-150

Love the TAD125. It is better for my current system than the 60. Livlier, more detailed, richer runs cool. The 60 was a bit warmer but, the 125 is a better match for my system and the music that i listen to.... How did the groove tube X7s stack up against the competition?

I really liked the GTs. But they were a little more "in your face" than the Telefunkens. But, the differences are not stark, just noticeable. IMHO the GTs have been a little better suited to rock but I listen to mostly Jazz and vocals. The Telefunkens to me sound clearer, crisper and more detailed focused. The Telefunkens seemed to refocus the sound stage. I could have lived with the GTs or the RCA 5751 black plates easily though, they would have been my second and third picks if I were forced to rank them. GT has a new tube (can't remember was it a 12au7 or 5751) but I thought it might be interesting to try (would a little less gain in the GT make a difference?).

Hoop,

Did you try Siemens-Halske X7's or Sylvania T7-WA's (3 mica). If so...thoughts?

Fishboat,

Siemans, No. Sylvanias, yes (may have been double micas though). I would have to dig to make sure. The Sylvanias I thought were very good. Nice detail but a little less body than the Telefunkens to my ears. But, I could have lived with them. I guess the reason I liked the Telefunkens was becasue they seemed to strike a balance between detail and body. I have not tried Valvos either and would have been interested in them as well as the Siemens. Bugle Boys seemed pleasant, but ultimately too bright after extended listening. Gosh, I just finally had to stop somewhere with the rolling-my wife threatened the UPS guy as well as me! she became much to aware of a potential box that may have a pair of tubes...

I ordered a pair of the Tung Sol reissues from Doug. I will review after I have had a chance to listen to them.
