I guess no one has seen this issue. I'll revamp the wiring. Maybe I was shortening the wire too much and put too much pressure when bundling it. Probably my bad. I'm very, very pleased with the Plus and EX I purchased. Fill the 2500 cubic room nicely and still need to do more research and get the SMS-1 calibrated properly for different sources(movies vs. music vs. video games). Only used the quick setup for now. And then comes the 978! Woohoo! Toward the end of year of course... ;-) Nice Christmas, then amp for Feb. birthday to upgrade the 750 I've had forever! New and improved is coming together quite nicely....
