I just went through something similar. I switched to Roon + Tidal. I purchased a Roon Nucleus( they are may other servers option to use Roon) that is feed into my Oppo 105 via USB, Oppo feed Into my Marantz SR7005 via analog. Very happy with results.
Almost embarrassed to ask, but...
I’m seriously considering a high(ish) end used pre amp as my next upgrade. Currently using Marantz AVP, and looking for the next step up in sq for 2 channel. I have an Oppo UDP205 for discs, but also use a lot of streaming music. The Oppo has the DAC, but I’d need to get the streaming music into it. From the Oppo I’d take analog out to the pre amp. I can use a tablet, but I’d prefer a stand alone unit plugged into the Oppo. Also, what is the best connection for digital output of the streamer to digital in on the Oppo?
