OK, so no one's reading this stuff except perhaps those of us who own the little amp that could. Well, for those few of us here's the latest:
Rolled out the Sylvanias (I had made some other changes in the system and lost some of what I had come to tap my toes to). Rolled in a set of Mullard ECC83s. Oh my. The soundstange came back, the imaging improved mightily and the layering of the musicians/voclaists became instantly (and I mean within five minutes of powering up) was really improved. It likely helps that I took an extra fifteen minutes to set the bias on the EL34s in the unit too but that probably accounted for the complete removal of sibilance more than anything. I'm looking now for a set of JJ Tesla E34L blue glass just to compare to the Svets which are already really nice. I'd get more Mullards for these but the price on the truly good ones is way up there.
IMHO for the 12AX7s that I have: Mullards are No 1 by a longshot with the OE ElectroHarmonix in second and the Sylvanias trailing by a lot. The recommendation I got that caused me to jump on the ECC83s was that the Jolida really likes Euro tubes (something to keep in mind).
I'm putting in a new PC tonight for the unit and in a couple of hundred hours I should have a read on what this does.
