Better sounding alternatives to Blue Node Vault 2i

I would like to re-store my roughly 750 CD library into one spot tp play via my existing system. The CD’s are on my computer already but digitized using iTunes default settings, so not exactly hi-rez and I expect to have to replay them for higher rez digital storage. I don’t need a new streamer since I’m happy with my Cambridge CXN V2 once I got an appropriate power cord and cables, vibration damping and so forth and spent the time to find stations to my liking.. The Blue Node Vault seems to do everything I want except really needs an external DAC and I’d rather find everything in one box. Existing system is an Audio Research LS2B MKII (with remote) feeding two Sumo Andromeda IIA power amps driving a pair of hybrid Acoustat 1100 electrostatics in bi-amp mode. Sony SA5400 ES SACD, Classic Sansui TU-9900 (max modified) tuner and the Cambridge for sources. Room is fully done by Acoustic Sciences with traps, drums and panels and the imaging is really something with good recordings. System runs balanced from the Sony to the Sumos but single ended for the tuner and Cambridge to the preamp. Single ended RCA would be OK for what I would like to add which I would prefer to have it’s own built in CD player, adequate storage for more than 750 CDs at hi-rez..... workable with a phone or tablet app and of course not be a weak link in the system. Any ideas?  Could go a couple to a few $K for the right piece.
