I am gunning for chewy/spongy feel, with a rich mid content (upper AND lower) with a somewhat limited bass response and smooth top end. I'm NOT looking for aggressive tones. Also, are you using these tubes in a Super Lead / 1959 / 1987 style circuit?
The closest I've found to that in recent production tubes are the Winged Cs, so far. But I'm itching to put in a set of NOS Mullards soon.
Also, don't overlook the effect of preamp tubes on what you're describing. They make a big difference, as my experimentation with NOS BRIMARs showed in my DG30. The BRIMARs were so much more classy sounding than the JJs in the same locations, it wasn't even close. In fact, I'm planning on trying some in my HXDA.
