Marantz NA7004 & Hi-Res FLAC

[simoncn]

As MinimStreamer is not installed, you are definitely not doing transcoding.

Regarding 1), there might be some interaction between the audio data in the file and the more aggressive compression performed by level 3 and above. For each level, FLAC has a number of alternative compression strategies and it compresses each block of audio data using the strategy that produces the smallest size. Depending on what is in the data, different strategies might be used for different files.

Regarding 2), are you sure Asset is not doing any transcoding? Another possible explanation is that the timing of sending data blocks from server to renderer is different with Asset and MinimServer and this different timing could be triggering the Marantz issue.

Regarding 3), I don't understand this as when you removed update 126 from 0.8.5, this should have been equivalent to going back to 0.8.4 update 114 (the last update to 0.8.4). Are you sure you didn't have transcoding enabled when you were using MinimServer 0.8.4?

The next step for diagnosing the problem would be for you to produce a debug log when the problem occurs. I will PM you with instructions for this.
