Distortion using OPPO 103 w Streaming and CD's, but not with DVD playback

Hoping someone can give some advice before I tear the rack apart.

Have an OPPO 103 for CD/DVD and streaming from Tidal.  Have owned the unit for years and happy with it.  I really liked the fact that it not only played disks but also had the associated app that allows me to stream from Tidal.

I hadn't streamed for quite a while and when I streamed today there was tremendous distortion (unlistenable), playing a CD seems to also be distorted, but not as bad, playing a DVD doesn't seem to have no distortion at all.

All connections are RCA / Single ended. 

There is one new variable and that is the introduction of a Schiit Freya preamp.

However, vinyl sounds great through the Freya and as I said above DVD playback seems perfectly fine.

So if someone has trouble shooting ideas before I start tearing down the rack and rearranging things I would love to hear them.

Seems weird that some functions sound fine and others are a mess and I would think that a bad wire, connection or even EMF would effect all of the playback media the same way.

Thanks in advance.

Phil-

you mention using single ended rca’s for connections to the preamp- have you tried  going coaxial to the preamp and switching the Oppo’s settings to coaxial out? I run this approach with my 105-D and adjust the internal volume control for matching.

Hi designfx,

My 103-D only has single ended outputs so that's not an option for me.

I have played with the Oppo volume vs the preamp volume and didn't see any difference.

I also ran a speedtest on my internet connection and that seems fine.

And someone else suggested rebooting and I did unplug the unit for maybe 20 seconds and then tried again, but no change with any of these attempted fixes.

I have occasionally had problems with my 105 that went away with rebooting, but sometimes it requires a few reboots.  Seeing as how Oppo discontinued these products a few years ago, and now the problem seems confined to Tidal, it’s possible that perhaps a Tidal update is causing a a compatibility issue.  Practically speaking the Lumin is what you will want to use for streaming anyway

Hi Phil-

I was just looking at the BDP 103 manual and there should be a coaxial audio output near the toslink output. This will allow the 2 channel audio to be sent from the internal dac to your preamp. Tried to send a screenshot from the manual but this sight seems to like web links only.🤔
