This is the 6N6P vacuum tube cryogenically treated. The sonic quality enhancement of this is no small thing. The 6N6P when cryo treated rivals the 6H30P-DR, and many have felt it sounds much better. We mark these tubes on top with an orange tip, this way you/we won’t get them mixed up with other 6N6P vacuum tubes.
This price is per tube.
We are a small company that prizes innovation above most everything else, if someone else does it better then unless we did it first we are not going to make and sell a product. We have enough repetition in this industry. We also cherish honesty, we won’t sell something that doesn’t make a sonic difference, in fact we want products that make a very real and noticeable difference. No guessing if things sound better in some way, no scam products that don’t do anything.
