PS audio or Moon

The interesting thing about the 390: its ROON endpoint capability.  You could do a ROON trial on a PC.  If you like Roon then build up a Small Green Computer Sonic Transport i5 to run the core and have a setup that could be better than a BS Node, depending on your goals.  The interface and Meta Data of Roon will open doors like never before.

Budget Solution: 

Rogue Audio Pre can be had for ~$1.2K , used

Moon Mind2 streamer $2.4K, new

Schiit Modius DAC ~ $300 new

Less than $4K your in with respected components

Negative: 3 boxes

Positive: You can upgrade each as disposable income allows 

I do a plug for PS Audio.  They operate less than a couple miles from my house and i have been through their facility. First rate. I have met Paul and he is really a nice person. I had the  S300 amp and had really good service out of the unit.   I wouldnt hesitate to recommend them.
