Too many times, I've found a change in cables to be the problem solver. And three times, this has happened with a pair of speakers that I was resigned to sell. Twice with speaker cables, and once with a pair of interconnects.
You will find a lot of exasperated owners of Soliloquy speakers during the break-in period. It all depends on how far you're willing to go to try and make it work. Personally, I think it's a shame to write off any component before I've allowed it to work to its potential. That could be via a change in cables, tubes, maybe even the orientation in the room. But hey, that's just me.
