Hi David! I remember you were pretty high on the Mapleshade cables a while ago. Are you still pretty much a fan?
While not having dealt with Mapleshade, I have returned a Stealth silver speaker cable in the past. Sergui was a nice guy, but seemed shocked to find out the cable did not work in my system. Claimed it was the only time he had ever had someone tell him it wasn't the best cable they've every tried. Told me my system was "extremely unusual and different from most 'normal' people's". Of course, I laughed, my system is about as conventional as anyone else's.
The speaker cables were about as dead and lifeless as any I have come across. Dynamics, soundstage, and even volume was worse than $1/foot stranded OFC 12 gauge cable. For those who don't believe that cable can make a difference, I say that cable sure as heck did, but for the worse.
And, I don't have anything against Stealth, as I was using their flat ribbon silver interconnect between my preamp and power amps with very good result. However, I can't complain enough about the Neutrik RCA plugs that terminated the cable. One of which had a pin break off, and get stuck in my preamp's jack. My only complaint with an otherwise competent cable.
