A signal from a record player (and that's all they are) has to be filtered through an RIAA response pre-amp to account for the output voltage being down to the frequency picked off the record. This is the biggest source of non linearity as no analogue filter can ever 100% represent the inverse of the magnetic cartridge due to manufacturing variations. An often overlooked fact as few understand what L.di/dt means. Rate of change of signal is lower at lower frequencies and has to be compensated for by an analogue filter. Michael Faraday worked this out. They may sound different, but none will be accurate. Digital audio has no such limitations. -- Waldo Pepper ------------------------------------------------------------------------ Waldo Pepper's Profile: http://forums.slimdevices.com/member.php?userid=39029 View this thread: http://forums.slimdevices.com/showthread.php?t=85590 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/audiophiles
