DSD on OPPO 105D

[maikeru]

Hi, I've read through the forums but no luck with my issue.

I'm dipping my toe into DSD downloads.

I am comparing SACD's I own with identical DSD downloads (e.g. Analogue Productions, so, to be clear, the masterings and data match).

Bottom line - I think there's a problem the way I'm getting the DSD to play on the OPPO.

When I play the files direct on a USB thumb drive, it sounds good.

But not in my normal config, which is:

Synology ds214Play-->MinimServer-->BubbleUpnP-->ethernet-->OPPO
all controlled with the LUMIN iPad app

I do have the OPPO config'd to force DSD playback.
I also have HDMI audio turned off.

The files play, but sound noticeably inferior to SACD and USB Thumb drive.

Any help greatly appreciated.

Kind regards,
Michael
