Yeah, I personally would not buy that unless I could inspect the internals. I’m strange like that. Furman crap made me that way, so blame them.
We already have a very good thread on this, by the way. Many of your answers might be there already. Power/Line Conditioner
Honestly though, I don’t think many people need much more than this https://www.amazon.com/dp/B0002QPC28/ref=cm_sw_r_cp_apap_1X1kzFUp77Aqo
If you get wild voltage fluctuations, a good power conditioner/regenerator that can step up or down the voltage as needed might be useful. They are crazy expensive though. @ValentineLuke linked one that seems pretty good. That UltraLink thingy won’t do that.
If you get noise beyond what a good filtering strip (like the one I linked) can eliminate, then I would suggest you hire an electrician. Something is F’d up in your house. Don’t bother with an isolation transformer because the real ones are 4 or 5 Focal Utopia’s MSRP in price.
Oh, and don’t run your air-conditioning / refrigerator / garage door on the same circuit as your audio gear.
