Shouldn't it be crisper/cleaner/more vibrant?

why don't you share what it was?

@cwhoward yes do tell - what was the solution?

@patrickalston Klipsch have never been known for having deep bass. They may have lots of bass but not really deep.

I read the manual online.  It has a section on placement that I’m sure helps + also addresses isolation from floor as needed. 
 

That should cover it.  After that I’d say on to DSP/EQ/room correction as needed. 
 

All par for the course. 
 

Or one can jump on the gear change merry go round and spend a fortune there while leaving a lot on the table still if the basics of setting up for good sound are not addressed first. 

Yes, what did you do to correct the problem!!!
