I’ve had the 3 x MC1 Pro Helix+ units in the system for about 5 days now. I have them all plugged into one wall outlet with the supplied piggyback cables, right next to the outlet that feeds my SR PowerCell. This seems to be a good place for them.
So far I like them a lot. They do have a very pronounced effect, and my initial impressions seem to be confirmed. They add precision to imaging and soundstage placement. If they are removed, everything is blurred slightly in an audiovisual sense. They add depth, dimension and refinement to image placement. They do not seem to enhance air and bloom in the way I noticed with the MC0.5. Each model has a slightly different strength. MC0.5 for detail, air and value for money, MC1 Pro Helix+ for soundstage precision and refinement. The effects are complementary and additive.
