MacIntosh Power Amp: What Power Conditioner Can Handle Peaks?

I have been using a PS Audio P15 "power regenerator" since it first came on the market, and very highly recommend it.  I have my entire audio system plugged into the P15 (McIntosh MC452/McIntosh C2500/PS Audio DAC & transport/Roon server and a pair of JL Audio F113V2 sub woofers) and I'm using about 1/8 of the AC power the P15 can deliver.

Wow..that is impressive.

Do you find an improvement with the power amp plugged into the regenerator vs directly to the wall?  I ask because the other advantage is evening out the power load on the house electrical circuit.

Dedicated line to your listening room. Be done with the gadgets. 

I believe that I would want four lines..a mix of 220 and 120.  It would require over 100 feet of buried power cables to reach my second garage and then probably add 220 to garage for future electric vehicle..but I prefer V8s..so I'm guessing a secondary panel in the finished double garage.  My listening room is above the double garage.  How do I educate myself as to how to do this for audio?  I'm pretty sure that the easiest approach preferred by the electrician is not the best approach.  I bet the EMF from the electric car recharger would be pretty wicked.

Thank you all for you input.  Have since read that multiple dedicated lines are tricky and can have unintended issues.  I opted for a Shunyata conditioner as my initial step.
