and if you really want to improve the sound of your system check out the Townshend podiums they go underneath the speakers and they stop the vibration from going from the speakers into the floor and back into your speakers and into your other equipment they isolate down to three Hertz the improvement is so great It's as if you upgraded your electronics it'll take your system to a whole new level and you won't even have to spend another $50,000 on another amp this improvement will be far better and they definitely don't cost as much as an amplifier but the improvement will be better than adding another amplifier.
