It is because of the analog nature of the ASRC chip, it is behaving like a DAC and therefore sensitive to input jitter. The ASRC will be good sounding if you feed it a very clean low jitter data stream. I agree with you that there is no difference in sound whether we're feeding 44.1 or upsampled 96K tracks once you have a clean input. For us TacT users, this thread is pointless. So it seems you're using the 2.2x on the effect loop on the Transporter? I'd be very careful not to rely on the 2.2x as volume control in this configuration. The 2.2x volume control on digital domain does degrade the sound slightly. -- Kuro ------------------------------------------------------------------------ Kuro's Profile: http://forums.slimdevices.com/member.php?userid=16701 View this thread: http://forums.slimdevices.com/showthread.php?t=69145 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/audiophiles
