Tubes for Lamm m1.2 Reference

Hi. I just wanted let everyone know I just replaced my stock tubes with the Amperex pinch waist 6922 PQ. Ok, was it exspensive? Yes, but the tubes are rare and getting harder to find. I paid $650.00 for the pair. Lucky the Lamm's are hybrids and I only needed 2 of these! All I can say is WOW! Timpany drums use to shake my music room, now it just destoys it.Please note, it is crytal clear destruction. Vocals are sweet but definite. sax and piano and acoustic guitars are right there and very revealing. I have been a bass player since I was 10 years old and have recorded in the best studios.I did the whole record label thing. This is the first time i feel as though I am listening to the two inch master reel. CD's really do suck.The Amperex are also quieter which is nice because the Lamm's have such a high gain. I post this thread for all the Lamm owners so they can make their amazing amps even better. I purchased my tubes from Agoner tas_audio. Alan is a great guy.
