Monster Regret!!

You should try it both ways and use what sounds the best.

I bought into all the Monster cable hype. I even went as far as purchasing their Monster Power AVS 2000 voltage stabilizer and HTS 5000 reference power center.

Why is it hype? Is there something wrong with the product? It maintains 120 VAC has surge protection, and a singles PS cable is taking care of ground loop issues, with multi outlets that are protected....

I'm sure a lot of  monster cables are just fine.. Speaker IC.. You might want to look around a bit..

I'm all for what sounds better, but cost the least.. MC said it, try it both ways, but "just because", someone else said PS  make everything better (sound) you may be in for a surprised... it should sound the same.
If they are both doing their jobs.. 

If you were using products with crappy power supplies, (not yours),
PS or even the lowly monster product, would show a marked improvement, bottom to top... That has been my experience over and over and over...

I'm a safety first, protect second, THEN, sound..
A lot of folks will disagree, but their not retired mechanics either...

EX: Mac.... Crappy little PC on any of their old Valve amps, if you replace it with anything other than what they use.. It's a waste of money.

Why, excellent Power supply design...

I wish you well, enjoy the learning curve..Spendy, though.

Your mileage may vary, though I was using a power conditioner, I decided to purchase a good power strip, just surge protection. That’s it. - hospital grade. 
I plugged my amp straight into the wall. The rest into the strip. 
I immediately noticed a much more open airy sound. 
I live in the land of dirty current of the 5 boroughs of nyc. Obviously components, synergy, and location determines if a Power conditioner is necessary. 
Shindo makes a nice power conditioner for under 300 usd. If I had to try another one. That would be my choice 

best luck

Simple age-old advice from @millercarbon.

I’ve been recommending ZeroSurge for years for high quality surge/rfi protection. Single outlet all the way up to whole house. They’ll even build you a custom device if you want...
