In your case, it should be easy to prove beyond any doubt whether or not a power supply change on your MC200 will make an audible difference to your 861/ID40

If you use a network sniffer such as wireshark, set up a playlist to send to 861zone. In wireshark etc, create a filter to only capture UDP packets between MC200 and 861/ID40 that contain the bytes AESDATA (iirc) - you will probably need to use a network hub or a switch that supports port mirroring.

Start the capture then start playing the play list. On completion, stop capture and save.

Repeat above in alternate configuration.

Compare the captured packets. If the content of the packets are identical, then there is absolutely no difference between the two configurations playing to your 861/ID40.
