After I purchased some power cables and began experimenting with them, I noticed that things which 'tightened up' the A/C power's waveform made the Bass 'thinner' sounding.
Do you use any powerline conditioners?
And if not, borrow one to try on your amp... it may help tighten up the Bass.
But I think your real problem is the room. A carpeted concrete floor is usually Bass neutral.
