Isn’t anybody going to mention that any old PC or Apple computer could act as a streamer? If your preamp doesn't have a compatible input, you could buy an inexpensive DAC that would take a USB input from the computer. The DAC would then be connected to your preamp / integrated amp.
You’d need software, that would run on the computer, that would supply the appropriate data stream to the DAC. I use Roon. Roon is equipped to receive the digital stream from Qobuz, and pass it along to the DAC. You could copy, or "rip", your CD files directly to your computer’s hard drive.
You can do it!
