I just found this thread and read with interest. This thread along with almost others of this kind, refers to prime Luna VS rogue an awful lot. I am wondering why these threads virtually never mention quicksilver audio? USA made, great reputation, same price range as the others already mentioned. I am in the market for good reasonably priced tube gear. I think any true comparison of reasonably priced tube gear should include this company and I'm not sure why that is not the case. Because they don't advertise?
