Luxman’s new Class A amps are nice as well, and a direct competitor to the Accuphase in Japan and similarly priced over there.(Accuphase gets a huge mark up when it crosses the pond). and of coarse the Pass Labs. I’ve had a Luxman Class A amp and was very surprised how nice it was from top to bottom and very musical. (Living Voice Speakers 94db).
I would go for separate DAC as it is the one component that does get out dated quickly with the ever growing digital tech progression.
I don’t think anyone does Class A SS like the Japanese they seem to have perfected it decades ago. Not to mention the attention to detail that they have.
