I owned a Raven Audio Osprey with best quality tubes and also Raven Audio Corvus speakers and was so happy with sound stage that it produced for 5 years.
But decided this year to step up to Raven Audio Reflection Amp .
A lot more money but they offered trade in on Osprey after 5 years and I had to at least see if my 73 yr old ears could hear that much difference...
At first I thought I made a big mistake but after the unit become broken in approx 6 weeks the sound stage is super wide and the instruments so much more punch and dramatic... But the cost was a hard sell but I am not sorry, for every time I play this Reflection and hear notes in music I have heard for years and never heard instruments and cymbals & drums like I do now...But the Osprey for approx 6k is a Amp that made me happy for years and you get to try it for 45 days from Raven..
Wish you all good luck in your search for best sound stage you can afford.
