Mswlogo, A couple of points: 1) you have left/right channels reversed at your soundcard input - hence the crosstalk of -6dB! 2) You and I are applying completely different methodologies... you are using the Meridian to apply make-up gain when you lower the TP volume. I'm not, so I am recording at a lower input level to the soundcard each time each time. If you really were using the digital volume control as a volume control, you wouldn't alter the Meridian level! You would set the Meridian to the loudest volume you wanted to ever use and then alter day-to-day vol with the TP level - for critical listening rather than background playing this would almost certainly be in the 0-12 range of adjustment. 3) I've just realised we are both making a minor schoolboy error in our use of RMAA :-). When you play a redbook file (16/44.1) via TP or Touch DAC, the DACs are being driven at 24/44.1. Therefore, to accurately capture the test we need to record the playback at 24/44.1. The differences are slight as you would expect. I've repeated my tests at 24/44.1. +-------------------------------------------------------------------+ |Filename: CropperCapture[1].jpg | |Download: http://forums.slimdevices.com/attachment.php?attachmentid=9877| +-------------------------------------------------------------------+ -- Phil Leigh You want to see the signal path BEFORE it gets onto a CD/vinyl...it ain't what you'd call minimal...
