Something to consider with a new streamer is Dirac Live.
Dirac Live resolves the soundstage with improved clarity and intelligibility with all instruments and vocals. With the room correction aspect you'll experience deeper and tighter bass free of resonances throughout the listening area, with greater transparency and the removal of distracting artifacts.
The miniDSP SHD Studio is a good example of a streaming high definition digital audio processor for users who wish to retain their existing DACs.
Dirac Live uniquely combines frequency response correction as well as impulse response (time domain) correction in the digital domain. Fixing time domain anomalies is an impressive advancement for any audiophile system.
The downsides are the increased complexity and effort needed to fully integrate Dirac Live, and also you may prefer he Bluesound NODE 2 user interface.
