Luxman L-590AX II or L-595ASE. Recently out of production and limited edition, respectively, but maybe you can find a dealer with stock or just buy used. It’s hard to get the richness and body of Pass Labs, but Luxman Class A comes close and is preferred by many for its sweetness and clarity. There’s also McIntosh autoformer amps but they are not as refined sounding as the Lux, higher WAF though.
