The OP has picked an interesting price point at $1.5K. In a Roon world, $1.5K buys a Roon Nucleus. You can further improve on that with another $500 for an Ethernet-to-USB renderer like the Sonore MicroRendu, and perhaps upgrade later from the mR to a SOtM renderer and USB conditioner.
But to support Roon’s impressive DSP engine, you need $2.5K for a Nucleus+ with an i7 processor. Alternatively, for around $1.5K you can install the Roon core with full DSP engine functionality on a QNAP NAS with i5 processor and expandable RAID storage. I’m using a QNAP TVS882 with one SD slot hosting Roon core(with sufficient computing power to fully support the Roon DSP engine) and a second SD slot to cache the music library stored on multiple disk drives in the RAID slots.
You pay a premium for the shrink-wrapped Nucleus, which may or may not be worth it, depending on your ability to set up and maintain a NAS. It’s not that hard to do, and it adds extra value as network storage and back-up for files unrelated to music.
