High end UPS for Expensive audio eequipments

Much depends on where you live.
Here on the East Coast, our power is pretty stable ( though I am now typing this on UPS supplied current due to an unexpected power outage).
Some parts of the US have more variable power and a power conditioner is of greater value.
As far as adding something in front of an amp, the guys at McCormack said, Nay-nay.- Just turn it off should the power go out.
I have had the power go off and on a few times while listening, and the amp was fine. (My other equipment was behind a power conditioner).

I have installed a whole house surge protector last year. I believe that it protects surge that comes from the outside power line. But it does not help if the surge is from within your home (start-stop of fridge, aHVAC unit, washing machines, etc). My power amp is direct to the wall, which is a 20A dedicated power line. The rest of the electronics are connected to Brick Wall PW8R15AUD surge protector, which is attached to another dedicated line.

If we’re talking purely on the basis of investment protection, Series Mode Surge suppressors are the only one’s I truly trust.

The technology is licensed by PS Audio, Surge-X and Furman, but Furman tends to have the lower prices.

A UPS often introduces more problems than they solve, and they are no guarantee of protection from surges.

Without prejudice to the performance degradation issues from the insertion of the surge protector unit and its filtering effects, High-end audio gear usually already has high-end quality build power supplies that do not benefit from any intermediary plug-in surge protection or power conditioners.

if surge protection gives you added peace of mind, then only add it as a quality build system-wide insertion by a licensed electrician at the Electrical panel rather than ANY wall plug-in accessory.
