My streaming and vinyl are very close. I believe the reproduction is quite good. I also know some on this board have better systems than mine and find vinyl and digital to be very close. The good side of this for you is that upgrading digital is far less expensive than upgrading analog. BTW..your system is extremely impressive..
I’m a bit confused as to what you use the computer for. Does it function as a music server? You said that you don’t use Roon…which I missed the first read through.
