Best sounding 6SN7 VT231 for amplifier input


Any thoughts on the best sounding 6SN7 (VT231 or Mullard) to be used as input tubes on an amplifier. In particular, which are the most romantic sounding? I have heard good things about the RCA Vt231 and the Mullard ECC32. Any other suggestions? To be used on ASL Hurricanes. Thanks!

Jeff;
Please add to your list Ken Rad Vt 231 & NU 6sn7 (both black glass).
Those are most romantic and sound awsome in my BAT amp.

Regards, Jack.
I'm using Sylvania in my SET amp. They sound great. I think Sylvania has the most transparent and twinkly high end.
in my amp:

--Kenrad (vt231) black glass = BIG, lush sound (but still open, unveiled), bass bloom, music full of weight, the BEST in my amp (but NOT in my preamp!)

--sylvania vt231 = sparkling (like TWL said... "twinkly") up top, crystal clear, extended

--sylvania 6SN7W (NOT the metal base) = also transparent, a little thin, tight bass

--tungsol, blackglass round plate = neutral, balanced, SMOOOTH (perfect in my preamp)

RCA grey glass vt231 = lush, but also veiled/dark

national union black glass vt231 = very similar to kenrad, but a little more veiled (still very good)

GE 6SN7 GTA = good all-around neutral tube, much better than stock/chinese tubes, nothing totally outstanding about it
