Generally I'm extremely happy with the sound of my system. I've recently been listening to an old favourite of mine, Fleet Foxes' Helplessness Blues and the close harmonies and complex instrumentation sound sublime, I'd forgotten what a fantastic sounding and moving album it is. There is, however, on occasion just a hint overly ripe bass bloom or overhang. It's not enough to make me consider any major changes - I think my amp and speakers are great and most music I hear with them sounds very well-balanced. The speakers are also just right size-wise for the space. My stands, however, are not fillable and I was wondering if filled stands (and maybe a heavier model of stands) might give me a more rigid platform for the speakers and help tighten up the occasional bass bloom I'm hearing.
