Power conditioner types

Knowing very little regarding
power conditioners...
they improve sound but do they protect equipment should
a power surge occur or are they
possibly damaged as well?
Appreciate your input regarding
the above mentioned Decware

Check for UL 1442 rating. If yes, then they are actually tested to protect against AC surges. If not, your guess is as good as anyone else’s.

Most surge protectors have limited lifespans anyway, so eventually they will wear out over time.  ZeroSurge/SurgeX/Brickwall are rare exceptions.

PS Audio's line is famous for doing just that.  PerfectPower was somewhere in between, storing enough energy to correct the waveform without necessarily being able to recreate missing waves.
