Upgrade from WIlson Sabrina

There’s no need for more stuff fat daddy. All that’s needed is the right stuff to effectively remediate the problem. Curb your sarcasm. 

I have Sabrinas and they produce enough bass to overwhelm a small room. The way I mitigated it was by placing GIK Limited Range tri traps in the corners behind the speakers in addition I have 204 bass traps. I also changed interconnects to Nordost Tyr 2 that are better balanced top to bottom without emphasis on any particular frequencies. Bass is right on at this point. 
Take a look at my system pictures. 

Ozzy62 thank you sir!

Gjohns - I sold the PSM 156. I found it limited dynamics even with just the DAC and preamp connected to it. Sound was pinched/too tamed.
Tried several power cords on it. No bueno. It might work in someone else’s system if that’s the effect they’re looking for but in mine I prefer the sound with all components plugged direct into wall. I am using Furutech GTX-D NCF outlets. Good power cords is all my system requires.
This is just my experience.

I would highly recommend running two dedicated lines - one for amp(s) and preamp, another for all digital. If possible. 

Sid…your 244 traps are full range. They are on the wall behind speakers and are not in the corners. You still have your corners accumulating bass and you still have standing waves. Your GIK panel placement is not effective as far as bass traps go.
What I was talking about is GIk tri traps with limited range. They go directly into corners and eliminate that extra space where bass accumulates, in addition to trapping bass and not affecting high frequencies. 
Your 244s will be more effective at first reflection points but don’t do a lot for bass trapping. 

you need two of these for each corner floor to ceiling 

@j-wall exactly what I’m telling Sid as well. Those 244 aren’t actually corner bass traps. 

Oh man that was funny as hell! 😂
