I remember when playing 192 tracks in the edit windows a high pitch whistle would occur for about 2 seconds and then silence on the forte output.
96,88,44,48 sample rates were ok.
However as mentioned playing back the 192 file in itunes was fine.
Maybe Im getting mixed up on the declick, would it be the riaa filters that are slightly better at 96 rather than 48?
If not then yet again it could be a figment of imagination and I need to ABX again!
