So are you suggesting that we all forget about any digital processing in the 1572 and use the analogue outs for all our equipment? That's not really an acceptable solution.
Also, this is NOT a handshake issue. It happens with the USB input. It happens with an optical cable. When the 1572 makes sound it is quite fantastic. But if I lose the first second of every track of an album I am playing off my iPhone then what's the point? They need to fix this and they need to make it a priority. The big features of the unit are the 10-band digital graphic EQ, the extensive DSP, the front USB input. These are the features that distinguished the 1572 from it's predecessor. What's the point if you use only analogue inputs? what's the point if it creates this repeated annoyance with every digital source? All pleasure is dissipated by the repeated annoyance.
No, I am not suggesting the analog inputs. I am suggesting outputting digital PCM via HDMI from a blu-ray player. There is no loss since every format (TrueHD, Dolby Digital, DTS, etc.) is converted to digital 2-channel or multi-channel PCM in order to apply digital bass mangement, EQ, etc. The only difference is whether it is converted in the player or in the 1572.
My suggsetion is the delay in the 1572 may be due to the 1572 searching for or switching to the correct decoder depending on the format. By inputting only PCM, the delay has vanished (at least in my unit). However, I grant you this may not work if using an optical digitial input (although you can also set your player to output only PCM via optical or coaxial as well).
