Streamer Recommendation.

Budget 7000US$.  (+/-)

System: Amplification: Luxman L 509X.  Speakers: Joseph Audio Perspective.  DAC:  PS Audio Perfect Wave.  CD/SACD PS Audio Perfect Wave.  Streamer:  BlueSound Node 2.I

I am limited to WiFi, due to my router location.   I would like a high quality streamer without DAC that will provide a noticeable improvement over the entry level Node.

Any assistance would be very helpful.
