***Is It Me Or Have Todays Modern Tubes Gotten REALLY REALLY Good***

About 3 years ago it was the Quad VA-One EL-84 amp that won my ears & heart.Almost 3 years I ran that amp night and day and never felt the urge to roll any of the tubes,which I believe were E.H...A user interface problem forced it’s sale and now it is the magical Cayin CS-55a with factory KT88’s,AU7 & AX7 small signal tubes..Once again I find absolutely no reason to start rolling tubes.Maybe,maaayyybbbeee I could squeeze a drop more liquidity outta the upper mids and possibly a hint more shimmer on top but at what expense?I hate gambling.Anyone else noting the quality of today’s new issue tubes?

Have an Atma-Sphere MP3 preamp with New/NOS setup. I use the  New Shuguang Treasure CV181-Z  to replace the 6sn7 and nothing NOS sounds better (and it's not even close).

For the 12au7 I use the old Amperex 7316 long-plates, which in my mind is the top 12au7. Have not tried any new 12au7 because I've been totally satisfied with the 7316's. If anyone knows a new 12au7 that could be better, I'm all ears

I think there's probably a mix in the New/NOS scorecard. Ease of availability/cost is a definite + for new tubes

I think the new production Gold Lion KT88s provide great bang for the buck.  So yes, I agree with the OP.

We designed all of our stuff to work with the garden variety of available tubes. Why saddle the customer with the need for a tube that is difficult to get?
My experience has been that the Chinese signal tubes are pretty good but for power tubes the Russians or the JJ (Slovakia) tubes are the way to go- depending very much on the tube type however- the Chinese are making some good power tubes as well.
