6SN7 Tung Sol Reissue Mullard 12AX7 any comments?

I have been using the Tung-Sol re-issue 6SN7s now for several months in my Supratek Chenin preamp. This weekend while listening with my wife I decided to swap the EH tubes back in to see if she and I would notice the difference. It was very apparent that the tubes were different. The EH tubes were more pronounced in the bass and MUCH hotter in the highs than the Tung-Sols. We both preferred the sound of the Tung-Sols, mainly because the EHs made our ears hurt due to the over-emphasis in the highs - I actually preferred the EH bass, but not so much that I would accept the highs. The Tung-Sol mids were clearly superior to those of the EHs. Neither is perfect, however.

OK Gang after a few years of experimenting much time and re$ources . . . I arive to soem clear conclussions.
There si no reissue that will take teh place of a good NOS.
Though must confess that Tung-Sol reissue are decent, they're not great nor wonderful.
I have bought tried tested and played with dozens of NOS types too many to list here but it shall suffice to say that i will list them in order of my personal prefference granted that every tube sound different in teh context of different gear even interactions and synergy (or lack thereof)with the otehr tubes in the system, be power tubes, driver tubes and pre tubes, phase splitter tubes, etc. also rectification tubes also influnece greatly.

So here we go:
1- Tong-Sol round plate black glass (1940's)best overall
does everything right tube

2- RCA gray glass (1940's)very close to TS sweeter mids
slight softness in the bass but lots of detail.

3- Ken Rad parellel plates ribbed clear tops 1940's does
everything right more and tighter bass than TS.

4- Raytheon ribbed plates extra support rods in front of
the plates unknown year but presumed early 1950's.

5- Sylvania chrome domes and bad boys 1950's

6- Tung-Sol tall bottles black plates black bases top halo
getter or harp shape getter.

7- just as good as teh Sylvanias and teh Tung-Sols tall
bottle come the Russian 6H8C NOS 1950's only the NOS
tubes they present an absolute wonderful bass celar and
airy top end a slight forward mids nto as sweet as the
Tung Sols or RCA's. Warning: newer tubes are same as EH
8- GE 1950's and early 60's (GTA GTB)not as refined as the
RCA's and TS but definetely not a sloucha dn will easily
better any new production tube.

Recent production tubes TS better than CHinese recent production tubes older production tubes sound pretty decent actually this is true for the 6SN7 only.

Interesting post, Gonzalo. I agree that I prefer old tubes to the new EH/TSRI, alhtough I would rank them in different order than you have them. In reality, though, I have found a mix of types sounds best. One other to try is the Shuguang Treasure tubes. They are as good as any old tube I have used. That's not to say they will sound best in any application, but they are certainly competitive, performance-wise. I am using early blue-glass tubes, not the final black-glass types. Supposedly the black coated glass are better. I suppose I'll hve to try them at some point, but they are very expensive.

Thanks Gonzalo, man, that you were back with your impressions make this thread realy special, thanks again! I am not like you, never tried any re-issues, except one time when I bought PrimaLuna Prologue Two, where the stock KT88 tubes seems to be a copy of Genalex. Well, let me tell you, they arent bad, but when I upgraded to NOS GEC KT88, there were NO WAY BACK to it, period.
I dont see Tung Sols Mouse Ears in your list, but also ECC33 Mullards are not there, so, if you still use 6SN7 based amp, try them out, best out there...love this!

I agree that the older tubes do sound better. Have not heard the new Shuggie Treasures but from what I am hearing they are awesome. Not sure I can afford them but maybe one day I can catch a good deal. I agree with Gonzalo with his list of favorites. For the most part as I have not heard some of the tubes he has but the RCA grey glass are my favorites so far. The TS round plates are crazy expensive and the Bad Boys are quickly getting there. Not sure if the Bad Boy is worth it as I have found a Sylvania that is close at a fraction of the cost.
