I've been shopping around my area (Thailand) and have found two amplifiers that I'd like to choose from: The Marantz PM7001 and the NAD C351. However, I'm having a hard time finding the speakers I want. So far I went into the B&W store, but found that they are asking a lot for the 686's ($900). The only other brands that I've been able to track down are Marantz, NAD, JBL, and Yamaha. I've also found a pair of PSB B-15 and B-25, but I don't know a thing about them. Can anyone be of help?
