I have an Accuphase A48 and I must say it is quite an articulate and powerful amplifier. Build quality is impeccable. I love it. Going up the "food chain" to their more powerful Class-A or A/B amps or their integrated amps I don't think would get really notable performance improvements over their lower powered counterparts. I find it disturbing that the US importer has to mark these up so much. Getting a Japanese market unit with step-down transformer could be an option however why have to go through this when a more modest upcharge would most likely sell more of their great equipment.
Also, there are many well regarded amplifiers and integrated's out there and personal taste prevails as to which is best. Pass Labs, Accuphase, Bryston, Coda, Sugden, and many more are all good, reliable products.
