Thanks for a lot of help. I didn't buy a streamer yet, but I note that the Bluesound Node is most recommended.
I guess I'm on catch-up with streaming, perhaps because I've got kids home or perhaps because I've been playing saxophone recently.
My current plan is to use the DAC in the Rega CD player. Run 100' of CAT8 cable from the upstairs FIOS box to the (as yet) un-purchased streamer and Kimber DV30 coax from the streamer to the Rega DAC.
One problem with this setup is that my amp will still have to warm up before I can stream. But, I don’t see myself moving away from my old Audio Research valve amp which still sounds real good.
