Just a few observations... If you have decent kit (Linn, Naim etc) then the power cord will make no difference whatsoever as the PSU will have a decent design to reject mains born noise. Linear voltage regulators internal to the amp can remove noise on the input.
A good switching power supply won't make much difference as such devices imported into the EU are certified to an extremely high standard in terms of conducted and radiated emissions. You think different then you have a dodgy power supply. Having spent a fortune on a mains cable will convince yourself that it sounds better. To save face more than anything. As for mains transformer resonances... You have coils with millihenries of inductance combined with nanofarads of capacitance. They will have such a low Q factor, they will not be a problem. The psycho-acoustics of music is a vast subject. It doesn't take much change in mood to alter perception. What is constant is the science which is often misunderstood and misquoted. As for directional speaker cable...This can be rubbished by school boy maths. -- Waldo Pepper ------------------------------------------------------------------------ Waldo Pepper's Profile: http://forums.slimdevices.com/member.php?userid=39029 View this thread: http://forums.slimdevices.com/showthread.php?t=78938 _______________________________________________ Touch mailing list Touch@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/touch
