@highend64 Yes, switching to low level, or a line level, would resolve the hum problem, but as you point out Rel much prefers the high-end connections. In some testing I did, it was apparent that the high-end connection sounded more responsive, faster. I didn't want to spend that much for a sub and not take advantage of it's full capability.
Same with going with a wireless connection, would fix it, but degrade its performance.
Thanks
