Given what you’re looking for, some brands I’d look at off the top of my head would be Coda, Atmasphere GaN, AGD, Bryston, and Ayre. Best of luck.
Persona B Amp Recommendations
Looking for solid state amp recommendations for pairing with Persona B speakers. I prefer a neutral sound, or only slightly towards warmth. Price range up to about $8000. AR LS17SE pre also in the mix and this is a relatively neutral piece. Something not too scarce. New preferred. Music is a mix but leans toward rock, some jazz and vocals.
