OK, let's get real for a moment: first off, anyone can fabricate an 'official' email that he has received from some representative (and if not fabricate, then at least doctor that email). So I wouldn't put too much stock into the quoted email. Secondly, and assuming that the above quoted email is legit and unaltered, are you honestly that naive to buy into the assumption that a Bryston representative would openly admit that the product they're building is less than perfect? Why would a marketing department ever do that, admit that a super expensive product they're selling is shipping with certain sub-standard components? It is only natural to see them deny that any improvement to their flagship product could ever be achieved in the aftermarket. If Bryston is shipping amplifiers, they're than expected to claim how all the parts are as good as they possibly can be. They will never, under no circumstances, admit that a power cable that ships with their amp is a terrible plastic piece of shit. Nor would they ever endorse a product that is being offered by another vendor on the market. If this fellow Chris Russell indeed wrote that email, I'm sure if were to put him on the lie detectors, those needless will be going off the charts like crazy! -- magiccarpetride ------------------------------------------------------------------------ magiccarpetride's Profile: http://forums.slimdevices.com/member.php?userid=37863 View this thread: http://forums.slimdevices.com/showthread.php?t=93210 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/audiophiles
