Thanks dhite71. That is great information.
I have a second system in my lake house where I am using a Node N130 into a Border Patrol DAC into a Mcintosh MA6500. I think I am going to sell the N130 and BP DAC and get an Icon for that setup.
I won't need the Icon there until spring so I will be able to test it in my main setup and see if I can notice any difference. I will report back with my findings.
