DSD dsf:dopwav transcoding issue

[gregi]

Hi,
dsf:dopwav - transcoding problem.
when i try to stream DSD file, dsf format from minim server.
it comes to my player Onkyo C-N5070 or Hegel H160.
and it shows format 24bit/176.4kbit/s but no sounds from players. like no D/A conversion.

but when I convert:
2) flac:wav24;176
3) dsf:wav24;176
everything is OK,
means players/renderers support 24/176 format.

does anyone has similar problem? is dsf:dopwav correctly supported by minim server?
thx in advance for any help,
