Help on power conditioner upgrade

Currently using PS Audio 300 with m/w. Equipment consists of Sony 333ES, Perp Tech P1 & P3, Bel Canto Pre-1, Bel Canto 200.2, and Legacy Sig III speakers. Everything except the amp is plugged into the 300. Looking at the following. All are priced around $1600 for used or demo. Auditioning is not an option.

Shunyata Hydra, Equi=Tech 1.5 or 2.0, Exact Power 2000, PS Audio 1200.

Not displeased with the 300 but I regard it as an entry level piece and I would like to plug in my amp and maybe even a second 200.2 down the road. Thanks.
