surg protection / high output amps

If you own your own home, I suggest a whole house surge protector.
They are self sacrificial, and don't cost much, though you do need a licensed electrician to install it.
But it does give you peace of mind, as well as protecting all of your electrical equipment throughout the house.

interesting thought ... and not one I would have thought of ... thank you ....

If you can’t go whole house, I second a Furman product... particularly in the Elite realm... they have many options.

I just bought this old old Power conditioner,

a desirable feature, besides protection, is the sequenced time delay, turns accessories on first, then 10 secs later powers the amp(s). Turns off amp first, delays 30 secs then turns off accessories.

probably too small for you, just thought I would mention that feature.

A friend has this currently available one, big enough?

I like the whole house idea too, 

new/used

after I bought mine, I read that IF they have dealt with spikes, repeatedly, there may be damage ... to parts within, never occurred to me, just passing what i read along ..
