Recently in Stereophile there were articles by Michael Fremer about how adding a generator transfer switch degraded sonics. The article included commentary by Garth Powell around some of the causal reasons. Fremmer "solved" this with a PS Audio regenerator.
I have two transfer switches. There is one for the primary whole house generator that kicks in 15 minutes following a power failure. There is a second smaller hospital-grade 240v 200kva regenerator unit that powers my critical automation systems, audio, and theater gear. The second unit is a battery based "always on" inline regenerator that bridges the whole house unit. There is a second transfer switch to take this unit offline if the whole house generator fails (this prevents the unit from going into permanent alarm status).
Downstream of this is a large 240v isolation transformer that provides 120v balanced power to all my critical systems, and that feeds a Shunyata Triton/Hydra setup. Less critial digital power supplies, etc. are further isolated with a Sound Application unit.
What additional steps might I take to avoid or mitigate the issues Fremmer experienced?
