Odd question. Bestbuy are a large US chain that often import hardware from the US. So if I buy a Yamaha AV amp - I'm thinking of the RXV667 here - from Bestbuy, will it be UK-tuned or US-tuned? I.e, do Yamaha tune the sound of their amps, like Pioneer and Denon do, IIRC, and if so, will the amp I get from Bestbuy be so-tuned?
