Simaudio versus Accuphase?

While Simaudio makes some fine gear, Accuphase electronics are in a completely different league as far as their build quality and performance. Of course they are priced accordingly, but much more reasonably in Japan as noted. I don't have any personal experience with your speakers so I can't comment on them directly.

Thanks Bill, i believe i can get the A-70 and the c-2420 for the same price i paid for the sim gear at japanese prices. I am getting the same impression. I just never heard Accuphase, but looking forward to. The other issue is fitting in the quadraspire rack, hmmm.

Harris, I heard the Serblin Ktemas in my Dealer's treated showroom 3 weeks ago paired with a Vitus RI-100. The sound was relaxed, yet dynamic, effortless, smooth and articulate. The Ktemas are good sound stagers. The latest generation of Accuphase instrumention type amps are beautifully built and have good power and control (which has always been the achilles heal of earlier models). Very nice eye candy as well!

You might have guessed i'm more of a Vitus fan, and own Vitus Signature series gear. If you can access genuine (non-gray market) Accuphase gear in Japan at good prices, that would be a safe bet as it has traditionally had good resale value.

Defintely go out and listen. I have had many listening sessions with Accuphase units. Believe me, it's some of the best out there, and at the Japanese prices, it's a no brainer. The only stuff that could possibly beat it is FM Acoustics and Boulder, at a million times the price.
The A-70 + C-2420 is a dynamite world class combo. I can attest to this. I have heard said combo, and it'll do all kinds of neat things sound wise. Plus it is transparent and dynaimc. Unfortunately I don't these superb units at the moment, but hopefully in the near future I will. The stuff isn't cheap here in the US!
