As usual, soix has the best advice :)
I owned an Innuos Zenith MK3 and thoroughly enjoyed it. A used specimen goes for around $3200-3500 nowadays -- maybe even less since they have introduced the Pulsar line. Consider what you're getting for the money ...
- Built-in Roon Core server; can easily switch back and forth between Roon and their proprietary Sense software. No need to buy a separate Roon server.
- The SQ of their proprietary Sense software, IMO, is noticeably better than Roon.
- At least 1TB of SSD -- great for downloading hi-res or DSD music; no need for a separate NAS
- Built-in CD ripper which is fast and easy to use
Lastly, I know there are folks who are very skeptical of tweaks, but I can speak from experience that replacing the stock fuse with Synergistic Research Purple fuse was quite a shocker. The jump in SQ was phenomenal. It's only $200 and comes with a 30-day money back guarantee. Don't ask me how a mere fuse can do this, but you have to try it to believe it.
