I think I've made a grave mistake.
You see, I picked-up my Indeed Hybrid at the post office early this am and I have been experimenting with only 4 of my tubes all day. I have 4 more in route, but I doubt that I'll ever listen to them barring a tubular disaster.
Stock tube: "Decent" is a great descriptor. From separation to freq response to overall presentation, "decent" comes to mind. This is after only 3 hours of burn-in on the 6N11.
NOS Mullard E88CC/01: 1 hour of burn-in produces very warm-sounding, great music. Everything is there, but there isn't any "preciseness' to it. If sound can be "too smooth" to show any real definition, this is it. I can see why Mullards are cherished as music tubes, but it's too dark for me. I may cook it for a day or two while I am at work to see if it changes any, but for now it's back in its 40 y/o box. My cMoyBB2.02 sounds similar, but cleaner.
Amperex Holland orange & white label (no globe / used) 6dj8: No high end, no low end, but very clean mids. Sterile sound, but extremely clear. One for the display case, but it's kinda ugly, too. Probably awesome in old military radios.
RCA 6922 (Made in Germany): My grave mistake. I don't think any other tube could ever sound this good. WIDE and spacious with incredible tight bass, sweet mids and crystalline highs. There is definition to every sound/note/effect. It makes my Zune sound like a stereo system from Patsy Cline to the Transformer soundtrack. I can see why these tubes go for ~$100. My 440s have been on my head for over 2 hours and I just hope that no one has burgled the house while I have sat here watching football and listening all afternoon. I don't know if it is a Siemens as I originally thought. The top has a large cross or X and there appears to be an 11 molded in the glass between the pins.Anybody got any idea of the maker? May be the best $20 I've spent in a long time...
I can't wait to try it with the S4s, but I don't want to get up, yet.
