Amp Recommendation for Vienna Acoustics

I own a pair of Vienna Acoustics Mozart Grand. Currently using a Conrad Johnson CAV 50 Controlled tube amp. I love the warm sound of the CJ and VA , but the bass can be a bit bloated and ill defined at times. I really like a nice clean,extended tight bass.
I was wondering if a different type of amp would help tighten up the bass - More power, solid state with a high damping factor?
I tried moving the speakers away from the wall an extra two to three feet and it helps , but does not solve the problem.
I have heard the Vienna Acoustics in show rooms with high power tube amps, different speaker cables,interconnects and still heard the bass issue.

I was curious if there would be a amp that would help this , or if I just need a different speaker to obtain the nice clean , detailed bass extension.

I have also tried subwoofers to see if it would help. It did help to a point . but did not solve the problem.
