i have playback DTS audio 5.1 CD( wave file ) like: enigma, pinkfloyd ecc.. without problem.
Correct, if you actually play the original WAV file, the information is sent to the AVR and the DTS MultiChannel is decoded properly. However you should be able to change that WAV file into a
lossless Flac or ALAC (Apple Lossless Audio Codec) file and the AVR should
still recognize that the audio stream is a 41,100 Hz DTS-encoded Audio stream and decode it properly into 5.1 sound. Both the Dune Players and Popcorn Hour players successfully do this since they either passthrough the original lossless file to the AVR or they decode the lossless Flac or ALAC files into straight PCM without any processing. The AVR then sees the DTS encoding and plays the files correctly. I am basically implying that the Q10 Pro does
not losslessly convert those FLAC files to PCM, but actually modifies them somehow (changing the volume or sampling frequency) so the AVR no longer recognizes the DTS 5.1 encoding.
Now back to the original discussion in this thread... the Q10 Pro current cannot decode DSF files (from SACD's), nor can it passthrough the original DSF files to my AVR untouched. Yes, you can convert the DSF files into lossless Flac. My conversion software's output sample rate is set to 192 kHz to make the conversion as close to the original as possible using the encoding power of my MacPro. But if the Q10 Pro cannot send the Flac file losslessly (or a PCM lossless copy of the Flac file) to my AVR, but processes it on-the-fly, it introduces enough sonic differences that make a difference when I hear them, and certainly causes the receiver
not to recognize the stream as a DTS 5.1 encoded CD.
