I don't think it's that Sean has a negative attitude to criticism - quite the opposite, in fact. I think it's just that, given a detailed technical knowledge of how the equipment works, he can't see any reason whatsoever for the behaviour you're claiming. Nor can I. (And thank you Sean, it's nice to see actual science used in a hi-fi discussion for once!)
I'm sure we can all agree that the sound that exists in your room depends on the electrical signal that comes out of the back of your Squeezebox - yes? So, for that sound to change, the electrical signal that comes out of your Squeezebox must also change. Agreed? Here's the difficulty. Sean has explained that 'switching the Squeezebox off' doesn't really do anything but change what's displayed on the screen. The hardware that drives the SPDIF output continues to do so, it just drives out zeros rather than music. There's no subtle internal change that occurs. In fact, given that you're using an external DAC, there really are very few variables that the SB could possibly affect even if it were designed to do so. - it could transmit a different pattern of ones and zeros. This would be a bug, and a dead easy one to spot simply by recording the SPDIF output digitally and comparing before/after. - the electrical characteristics of the driver could change, giving more or less noise, jitter, overshoot or other recognised degradation of a digital signal. These are defined by the choice of driver, PCB layout and clock source - hardware parameters that are set when the SB is manufactured. Fiddling with the remote won't change those. I don't think anyone's saying that you don't hear a difference - only that it's virtually impossible for the Squeezebox to actually be behaving differently when it sounds 'good' vs 'not so good' to your ears. -- AndyC_772 ------------------------------------------------------------------------ AndyC_772's Profile: http://forums.slimdevices.com/member.php?userid=10472 View this thread: http://forums.slimdevices.com/showthread.php?t=36503 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
