It sounds to me like a room thing. I find speakers sound MUCH different in different locations, especially in the bass. My guess is that the mids and his aren't recessed as much as the bass is overwhelming them. Are the speakers closer to corners than they were before? Is the room smaller? Both of these things can boost bass. Also, check to make sure that none of the drivers (individual speakers) are damaged. Maybe you have a midrange or tweeter that isn't working. Maybe you were so excited about the new amp, you cranked it to 11? Or maybe damaged in the move? Put some music on QUIETLY and listen to each driver up close to see if sound is coming out. By the way, many of us listen to various types of popular music. I understand the stereotype (pun intended)- boring middle-aged guys closing our eyes to see if we can picture Diana Krall standing in our living room (which we do), but most enjoy a wide variety of music.
Also, what you describe is not what many people would call good. Most audiophiles value a clean, articulate, non-fatiguing midrange over all else, and would prefer weak bass to booming thumpy bass that obscures everything else. So, No, this is not what "good" sounds like.
