Music Server Advice

I’m an analog guy moving up the digital path and I’m asking for some help from my AGon colleagues with my next move. I currently use an Intel NUC/Rock to run Roon feeding an Esoteric D-05x. It really sounds good! If this sub $700 NUC sounds this good, I’m keen on discovering what can be had in the $4K to $7K range (New or Used) to replace the NUC/Rock. (I’m not letting go of the D-05x!) I’ve used Roon since its inception but I’ve tried other apps from time to time, most recently the Aurender App as well as Innuos, JRiver, and Audvirana.

Recently owned/auditioned:

Aurender N10 - Loved the sound, hated the App (to be fair I was comparing to Roon)

Innuos Pulse - Lots of detail no soul. Couldn’t listen to very long, fatiguing

Auralic Altair G1 - Mid Fi. traded in for Esoteric/added NUC Rock

Under Consideration:

- Go back to the N10 and get used to their app

- Aurender N200...get used to their app

- Antipodes...

I’m open to suggestions!

Digital: NUC/Rock - Esoteric D-05x - Esoteric F-05 - Wilson Sohia.

Listen to 95% Jazz.

Appreciate all responses in advance!
