Electro Harmonix tube opinions

I have a pair of the EH6922 gold pins. I Like them, but they don't get along well with my preamp. So - I'm not able to use them. In my preamp they caused a distortion at certain high frequencies. I'm sure it's some sort of odd occurrence. They'll probably work well for you.

I have their 6922 non-gold pins, and I like them much more than Phillips JAN NOS and Sovtek. In particular, I found the Sovteks harsh. The EH were much more fluid and relaxed with more details.

Good luck.

I have a set of the 6550's in my Graaf push pull amp and think they sound great. That being said I just got the amp pretty recently and haven't done any rolling yet, so we'll see. Still I think for the prices I've seen they're excellent tubes and they appear to be well built.

well, this might not be directly related as my experience is with the 12AX7EH whereas you want info on the 6922EH. However, FWIW, I like the 12AX7EH tubes in my CAT preamp. It lends a certain richness to the sound that the Ei12AX7 tubes do not. In my particular case the Sovtek 6922-12AX7EH combination works quite well & I've been happy with it for about 2 years. Overall, after having spoken to a number of people I know who use the 6922EH & reading the forums, I think that the EH tubes, in general, are very good no matter which one you pick.
I have *heard* that the 6550EH has a certain boom-boom quality in the bass. By 'boom-boom' bass quality I mean that the bass tends to show some over-hang & that it might be tending towards a 1-note bass character. This is 2nd-hand knowledge so weight it as much as you like. YMMV.
