New spreakers sound great But

Moving either your speakers or listening position (or both) closer to the wall will often increase the perceived bass. For a quick test, go stand up against the wall and see if the bass improves.

If that's not feasible, then you might consider adding one or more subs.

How new is "new?". May be a break in matter. My home speakers were very muffled on the bass until about 200 hrs of use.

What speakers are they?

Get a sub woofer.

i went through a similar not-enough-bass crisis when i switched from a parasound amp to the rotel rb980 to power my naim arrivas (which actaully extend quite low). the after much experimentation and a lengthy forum thread, i ended up adding a sub, which improved matters; however i still suspect that the rotel is just not a good low end performer and i'll probably replace it one of these rainy days.
