CR:
OK and all is good. I'm really pleased with them as well but you knis, reading about an even better driver, makes me curious... thanks for your answer, and the PM
Pstrisik: I only have one extra set of the 6V6, currently using a Genalex gold Dragon, and the ones which came with the amp as backup. The Genalex wasn't to expensive, $50 or so. But I want a few extra pairs so any recommendations are welcome. The opportunity to roll tubes in the MT is almost to big, five different tubes on both sides makes a lot of options... Had great success with the mullard 12au7 and tesla ez80 instead of standard ez8181but really need to read and learn more about tubes.
Btw , any one here have experience with transcendse otl amps, want one for my audeze LCD2s..
