I think some of the Accuphase integrateds are class A up to a wattage that would drive those Heresy IVs pretty loudly. Prices in the States are a bit steep, though.
Pass Labs INT-25 or equivalent in another brand
I’m interested in a Pass INT-25. I want to try a class A amp but I’m open to A/B. I currently have a push/pull tube amp and run Klipsch Heresy IV speakers. thoughts?
