2 Bryston 7B sst2 and PS Audio PS-15 Power Plant Regenerating Power Conditioner?

My gear is 2 Bryston 7B SST2 and 3 7B SST amps a Marantz AV 8805 with a set of Wilson Sabrina fronts and Wilson 3 center, good rears a CD and a Apple streamer etc. All my cables are Transparent Audio Reference Gen 5. My problem is that I’m stuck living in a condo until my home is built. Living in the condo forces me to draw power from one 20 amp breaker. I’m always running on the edge of how much electricity I can draw from that breaker so I’m looking for a work around because I can’t add a dedicated circuit in the condo. That’s due to being a renter. I have read a # of recommendation for Bryston amps and most state they should not be plugged into a power conditioner. But in an attempt at gaining a bit more “headroom” on the breaker and more control of the power coming out of the wall I’m considering buying a PS Audio PS-15 Power Plant Regenerating Power Conditioner.
I’m unclear if it would really help in my situation or not and I don’t want to spend money and the end up with an expensive unit that really doesn’t help.
Thanks.
