TMR has a Bryston BDA-3.14 streaming DAC. The Manic Moose interface is a POS but the Bryston is Roon ready. Load Roon on your home computer and use the BDA as a Roon end point. Bryston DAC sounds smooth, laid back and has plenty of warmth. Exactly the sound signature you seek.

However, you have a bottleneck in your system - your schiit preamp. May be worth ditching your entire low-fi front end (BS, Schiit and Glass) for something like the used Simaudio Moon 390 which is an all in one DAC/Streamer/Preamp here.
