Aurender.
After years of iPods, iPads, Macs and PCs I finally bought an Auralic Aries G2, then an Aurrender N100, listened to a N10, and bought their flagship W20SE. Aurender understands how to build streamers. So does Linn. I recommend one of these. The best you can, then over time you might consider a Audio Research DAC. I used to own a sonic Frontiers CD player (with an SF DAC)… nice tone but short on details (very short)… the ARC will give you natural sound with tons more detail.
