Hififile, without being crude, they suck big time. Compared to NOS 12AX7 tubes, the JJ's sound broke.

New Tung sol 12AX7's are excellent. Best I have heard even over NOS in several applications, and yes they have that big warm but dynamic sound like good NOS. Only ones as good are the Telefunkens, MAZDA's, & Baldwin/Sylvania tubes running between 200 and 300 per matched pair. So you can get these at like 40 per matched pair well worth it easily the best buy today in current production in my opinion. JJ not nearly as good from my experience, of course I think EH sucks too so maybe its just taste at the end of the day.
Thank you for the information Teajay and Apachef1 and Undertow. These were recommended to me by a customer service rep at one of the big online Tube vendors. I wanted to do my research first and fellow A-goners usually have good advice.
Thanks again and keep the info coming. I will be interested to see if anybody had good results with the JJ Gold Pin Black Sables.
I agree with the few who have said that the JJ 12ax7 don't sound very good. I much more enjoy both the early Siemens 12ax7(Ecc83) with the dual support on the getter and the infamous Mullard late 50's with the "D" getter. However, the new JJ EL84 power tube is very good in the right amp. There is more input on the tube asylum from other users of the JJ 12ax7:
