I have been thinking seriously about changing from a hybrid to an all-tube integrated amp, and the Raven Audio Osprey at 30 Watts seems to be the ticket for a fairly sensitive (90db) speaker. I like Dave the owner, and have spoken to him at the NY Audio Show, and corresponded with him by email. (His company is now moving into speakers and cables.) But, I only know what I read from the Raven website, and the few "professional" audio reviews who have written about their "Avian" amps on-line or in magazines, all of which has been good to very good. What I would like to know is what is the reputation of Raven among the tube cognoscenti? And what do you think about its: (a) Quality? (2) Sound? (3) Customer service? The fact that the Osprey costs around $5K is not a main issue, considering the cost of other tube amps. I realize it's moderated expensive, but I want to put together a long-term excellent system. Thanks.
