I have a pair under Legacy Aeris speakers and think the Townshend's have many positive attributes. Most dramatically, they cleaned up boomy bass - or resonant bass, which had the audible effect of making the mids and highs clearer. I also feel due to the vibrations being dampened, it isn't transmitting all of that to the equipment, which can only help.
In overall perception, I can see where someone might feel there is less bass because bass is no longer generated into the floor and creating thick (but muddy) sound. However, bass is faster, more accurate, and less "one-note" sounding, so I highly recommend them.
