Can a California Audio Lab Delta D/A be used with a FLAC USB music collection?

Yeah it'll work but the BluSound persistent queue is a PIA for playing local files.

 If I remember correctly, the Delta was a transport. The Alpha and sigma were the DAC units. I had a Delta and Alpha pair way back when. The Alpha was an good DAC back then. The Delta was a mediocre transport. The problem is that neither the Alpha or Sigma have a USB port. You would need to buy a converter to connect it to your computer. I would just buy a streamer or modern DAC.

 I use modern DAC with USB input that is connected to a laptop computer. I simply use Fubar2000 to play files. If you decide to get a modern DAC, check to see if it needs USB drivers. A lot of the newer DACs don't need drivers. And driver availability for new versions of your operating system could be a problem.

Thank you, LostBear,
Thank you for writing.  You are correct, it is the CAL Alpha that is its D/A.  So, I COULD use the CAL Alpha, but I would need a converter. Is this simply a cable with USB at one end and RCA for the Alpha at the other end?  So, I would plug the USB which has the music collection into the converter which would get the digital infor into the D/A of the CAL Alpha, but how will I be able to choose albums, artists, etc. since no screen will be available? Your assistance is much appreciated
