Yep ! The guitar amplifier and the "golden ears" tube-type stereo guys go "ga-ga" over these things.
I have a brother-in-law who's one of the "golden ears." I gave him a handful of 12AX7's -- he was able to describe how each different tube favored different musical instruments -- claiming he could clearly hear the difference. Of course, these guys invariably fail "blind testing" generally claiming that the rest of us just don't understand -- Amplifier guru Bob Carver challenged the "golden ears" of Stereophile magazine to tell if they were listening to multi-thousand dollar amps or his much more inexpensive one in blind tests. They couldn't. As a result, he was banned from ever advertising in Stereophile magazine again. Check it out at http://en.wikipedia.org/wiki/Bob_Carver . For best results, align the plane of your output tubes with the North Star -- And these guys are real!!
