Klimt The Bluesound Node has an acceptable DAC built in so it has both digital and analog outputs.
The analog outputs would work with your Denon.
When/if you get a new integrated that has a DAC in it, you can use the digital outputs on the Node to utilize a better DAC.
BTW, I replaced Emotiva separates with a Parasound New Classic 200 Integrated amp and haven't looked back. I'm enjoying it's many features and excellent sound quality. It has a better DAC than my Node so I use the digital outputs and it has a phono stage that supports mm and MC cartridges. At $1300 it doesn't quite compare with the $3000 integrated, but it leaves you some cash for a turntable, cartridge and some better cables.
