I have not tried Primephonic. I have a large collection of LPs CDs, tapes, some SACDs, and quite a few BD discs of mainly opera. I also have a large collection of concerts on my DAW, from broadcasts. I can get the BBC via VPN, and their quality is fantastic.
I do, do a lot of streaming, and subscribe to a number of top quality streaming services. These include, The Berlin Philharmonic Digital Concert Hall, Medici TV, the Metropolitan Opera Player, the SPCO concert library, the Detroit Symphony Orchestra. Recently the DSO have added a subscription Digital Stage. The Philadelphia Orchestra started streaming about a year ago. You have to buy a ticket for their concerts. They are $17.00 per concert. The Minnesota Orchestra has also started streaming it's concerts for the last several months. The Metropolitan Opera in addition to Met Player, has had artist recital concerts, which a $20.00 each, over and above the yearly Met Player subscription. There are a number of others also, but those are the ones I use on a regular basis.
All of those I have mentioned give you picture and superb sound. Also don't forget YouTube. There are lots of great offerings to be had there. One of my favorites since this pandemic began, is the concerts, nearly 30 now in lockdown, given by the
Scott Brothers Duo. That is one you absolutely should sample.
There are others out there, but the ones I have mentioned are ones they are really well presented with good AV quality. The BPO have a vast archive going back to the Karajan years.
I have to say, that I think a good HTPC, is by far the best way to navigate, explore and enjoy all these fine productions.
