@lanx0003 The dealers typically allow customers to test the new unit at the shop, and provide a 7-day return period. I spent a month listening to it and was confident that it will work fine afterwards, given the reputation of Accuphase products.
Given the price parity, I took a gamble as it would be painful to send the unit back for repair. The warranty period is one year.
By the way, it is a custom that the retailers there quote a price at 15% below the MSRP, even before you negotiate with them. Promotions with further discounts are common. I rarely get that in the U.S., which is a big reason I buy used or order online. Perhaps people in other areas have better experience than me..
@pinwa Thanks for the comments on the A-300 monoblocks. Will audition them along with the C-3900 preamp when I get a chance. Heard the power amps will operate in pure class A at 60 watts or under.
Another end-game option to consider is CH Precision C1.2 + M1.1, at an MSRP of $95k.
