Retro Matic owns a number of CDs from that library, which you can check out on his personal website.
I still say that someone has to sponsor him for him to prioritize sharing what you need
In fact, I often sponsor him so I can get what I'm interested in.
I don't think anyone on this forum owns some of Davenport's CDs.
Or some online shopping platform owns some CDs
BTW, I have purchased a piece of music from the Davenport Music website and they only offer MP3 320KBPS
