I don’t know your speakers but another thought might be a Rogers High Fidelity EHF 200 Mark II integrated amp. Rogers is selling directly a used one w/ their full lifetime warranty for $8500 or best offer. I own one & it’s substantially better than a Prima Luna in build & sound quality..His amps are hand made, all pint to pint wiring w/ top quality components. It’s pretty big, puts out some heat as if offers over 100 watts / side operating fully in class A running a total of KT - 150’s. Big, full rich sound w/great dynamics & bass & beautiful mid &top end.
I believe in & like to support , smaller independent, American made products & Roger is a very smart guy who designs & build his products in North Adams, MA.. check out his videos on YouTube or on the website.
