dsf to wav : what CPU power ?

[simoncn]

Thanks bubbleguum for this information. I think the results can be explained as follows:

"dsf:-/dopwav" plays DSD64 files as PCM24/176.4 and DSD128 files as DSD128
"dsf:-/wav24;176" plays DSD64 files as PCM24/176.4 and DSD128 files as DSD128

There are two streams. When playing a DSD64 stream, BubbleUPnP is playing to the non-OpenHome renderer. Because of the compatibility check, BubbleUPnP selects the second (transcoded) stream. When playing a DSD128 stream, BubbleUPnP is playing to the OpenHome renderer. Because there is no compatibility check, BubbleUPnP selects the first (untranscoded) stream.

<empty, no values> plays DSD64 files as DSD64 and DSD128 files as DSD128

There is only one stream and BubbleUPnP is playing to the OpenHome renderer. Because there is no compatibility check, BubbleUPnP selects the single (untranscoded) stream.

The problem with this explanation is that it isn't clear why BubbleUPnP would select different renderers for different stream types and/or the one-stream vs two-stream scenarios.
