Mapleshade "CLEARVIEW DOUBLE HELIX" speaker cables

I'm using Mapleshade's Clearview Golden Helix in a second system and was impressed enough to try their Double Helix Plus version in my main system (Classe Omicron -> Transparent Ultra -> Thiel CS7.2). The Double Helix Plus in this setup had a sweet lilting musical quality lacking in my Transparents. Less hi-fi sounding. Subjectively I (literally) felt the Double Helix Plus had deeper bass extension. Treble also had more air, cymbols for example had a more realistic quality. The downside was a lack of overall weight to the presentation, most noticeable in the mid-upper bass, and the sense that the music lacked the weight/power/energy of a real performance. In this regard the Transparents work much better in my system and offset some of the finer qualities of the Mapleshades. I'm returning the Mapleshades, however I would still recommend them. One other consideration is setup. They are tweaky in that you have to 1) keep them off the floor, 2) keep the +/- runs separated by at least 6".
