Got one of these from JoshB; recently noticed the tweeter was disconnected. Hooked it back up to find it's a hissy little thing. I searched here & HC to find some complain of the hiss, others seem not to notice or care. My question is this: Would replacing it w/a better-quality tweeter be worth the effort? I've also considered adding a pad; a slightly-more-electronics-&-sound-engineering savvy friend suggested that having a certain portion of the highs coming through all the time might be the problem. BTW, I did search before starting this one.
