Hi pchan,
I have a pair of HS8 and the GNS-MS01 for the Genos in the middle of a room size 11 feet x 20 feet. The Genos main outputs are connected to a 16-channel mixer, which outputs to a Radial ProD2 stereo direct box, which connects to the HS8 speakers with XLR cables.
I tried different combinations of HS8 placements, and found that they work the best at ear level, slightly facing inward for optimal performance and stereo separation. HS8 placement on the floor affects stereo image, separation, and complicates sonic characteristics, does not justify their high cost. I did not purchase the subwoofer HS8S because the HS8 pair already have decent bass. I purchased a pair of heavy duty speaker stands with adjustable height for optimal placement of the pair of HS8.
With some tweaking of main compressor values on the Genos, the GNS-MS01 performs admirably, with the advantage of space saving, and heavier bass than the HS8 speakers, which are known for their flat frequency response.

Thanks,
