Do you use an upgraded power cable to your 2170? Have been told this makes a genuine improvement with Class D amps and am getting a Nord in a week or so. Will not, btw, be buying a $3k power cord...
As your post suggests, I am very, very tired of cable connections. Have 15 large boxes of cables in the garage (neatly categorized, LOL) and still have to get an additional premium cable every time a new component arrives.
Did you decide on the HDMI or USB connection from your server to the Langdorf? Found with the Emotiva XMC-1 that the HDMI connection to the computer was significantly more linear than the USB one. But this might be the results of the XMC-1's architecture.
Enjoyed your noise comments -- thanks.
