Best steaming DAC with room correction
I'm looking to upgrade from my current streaming set up which is Google Chromecast audio feeding into a McIntosh 6700. My speakers are the Revel 228 Be. I listen to 100% streaming content; most Amazon HD. Budget is 5K or less. I really like Amazon HD over Tidal so that feature is a must. I also have a suboptimal living room set-up; hence the need for room correction. I was leaning towards the NAD 658. Thanks for any suggestions audiophiles!
