I never thought the sound of the OEM EH 6922 was bad. Nothing jumps out at me, brittle highs, weak bass etc. It's just I have no basis for comparison. FWIW, Keven Deal from up scale audio gave high marks for the new EH 6922, but he's in business to sell tubes. Shannon Parks is a real nice guy. He always answers my emails about the Budgie. I think I may be better served putting the money for NOS tubes towards adding to my record collection. I think sometimes we go nuts over the gear and forget about the music !
That's what all this is about in the end.
Cheers
