Vintage tubes vs Current tubes?

although i prefer vintage tubes, the tube circuit is critical in revealing or not revealing the differences in performances between current production and older tubes.

i just spoke to lyric hifi regarding the mcintosh 2102 amplifier. i am looking for an amp, cd player and preamp--all tubes, and have been considering mcintosh products.

i was told that the 201 does not change its sound when the driver tubes are replaced. i am also considering the c 220 preamp. it may be relatively insesentive to tube changes as well. certainly, my bat vk d5 cd player hardly changed sonically when i used amperex and mullard 6 volt tubes.

the bottom line: a difference makes no difference if you don't hear it. many of the current generation of tube products are designed around current tubes and are not responsive to changes in tubes.

So far the Cryo'd tubes I have tried I like...
The cryo'd ones i've tried are Svetlana el34 ( quads )
E.I. 12ax7( pairs )
GE 12bh7a ( nos cryo pairs )

These I like but it is a crapshoot wether it be nos,cryo or just plain new tubes.What works for some may not work for others...

Which tubes work best with different system depends upon the system and the ear of the owner. I have tubed rolled many different new stock and old stock tubes in various applications, using myself and other audiophiles as judges. I have yet to find any new stock that outperforms good old stock, even new cryoed tubes(they are an inprovement but tend to be fatigueing over long listening periods).Tell us what equipment you are using tubes in and what tubes you have used
