My experience after lost of 20k$

Amir57bs-you don’t have $20k in that digital setup and those pieces you described are far from the best. You can get a much better digital setup for 1/2 or even 1/3 of $20k. Actually, IMO, you don’t want to go with a pc/Mac front end or using usb to hook up an external dac.

Roon Nucleus with a WD 2 tb USB drive to a streamer of your choice.  I recommend a Bryston Bdp 3 to a BDA 3 DAC.  Even with some snazzy cables that rig runs in way under 10k.  No PC, no Apple.  Rip files via db poweramp. Ripping does require a computer with a drive.   Add Tidal and just listen to music.

Maybe all he needs is to burn in his USB cable a little more. Lmao. 

There maybe a valid point underneath everything here.  PC Audio can be very good, but at best, it may equal, but not exceed, the best disc based replay.  Frequently, it doesn’t meet the standard of disc based replay.  I would put the cash in the increasingly difficult task of finding a good CDP, and use file based replay as a less expensive and perhaps more convenient alternative.

I stream from my Mac mini to an Ayre QB-9 DSD and am extremely happy with the performance.  I listen to ripped hi-res music as well as Tidal streaming and haven’t turned on my Esoteric DV-50 in almost a year which tells me all I need to know.

PC audio is the present and future.
