I don’t have the long term experience owning many tube amps like some here have, but I’ve done a bunch of research and listened to quite a few systems.
My 2nd tube integrated (which I own now) is the Raven Audio Osprey at around $5K. They sell direct only so no dealer margins to pay and offer a 45 day in home trial for a nominal restocking fee. Service is exceptional.
I like the sub-out with 80Hz filter/bypass feature - it drives my 2 RELs.
I’m so impressed with Raven I’m trying to upgrade/trade-in the Osprey this year for 100% of it’s purchase price to the $15K Refection.
My system is detailed in my profile.
