I can't speak to the IC's, but I love the Mapleshade speaker wire. Its more dynamic than anything else out there, or at least the 10-20 that I have tried in my system.
Problems with Mapleshade cables
In june of 2013 I bought two pairs of Excalibur I/C's and speaker wire from Mapleshade audio. I've used these before many years ago and realize how delicate they are. On arrival one of the two meter pairs didn't work, was sent back, repaired and told that I ripped the conductor. They reluctantly fixed it for free. Now one week ago the one meter I/C (connected to Oppo-105) suddenly stopped working after being in place for 3-4 weeks, but would function on another piece of gear. It's now being repaired for $45.00. The two meter I/C they repaired is now playing games and dropping the signal intermettently (connected to Odyssey amp), requiring a mild crimping. My question is, has anyone else had this type of problem with these I/C'?
