Absolutely none of the above would prevent you from bringing the MS600 into the main listening room and connecting it to your G61 (for the moment).

Use MConfig to add the MS600 as a Source leave the C15 as a separate Source for comparison's sake.

Connect the MS600 to the same Network as the C15.

Select a Track on your C15 and choose the Output as the C15 Zone.

Then play the same Track using the MS600 Zone.

See what you think?

After that, you can then try cabling the MS600 Directly to the Front DSP pair but maybe consider that as a slightly longer term project.

All of the above would likely take about 5-10 minutes to set up and listen and it's well worth doing as you can see from all the similar posts here encouraging you to try it.
