Power amps into surge protector/Conditioner or DIRECT to wall? Final verdict?

I once plugged a power amp directly into the wall.  Did not sound good.  In fact, it made no sound at all.  The resulting hole(s) in the wall had a very low WAF.

there is really no point in plugging amps into surge protection powerstipes, etc since sonics are effected. Best bet is probably make sure equipment is well insured

I didn't mean to make such a blanket statement. A high quality power strip will not degrade or restrict the sonics of an amp. I believe some Furman models claim that an amps sonics will not be affected. But I have found that an amp into a passive conditioner does affect its sound in some manner.
Check out the Furman line of power stations. Try one that has a 30 day return policy.

Many power reconditioners such as PS Audio are built to accept an an amp since they are taking AC from the mains and generating a new clean signal for the components.
 

A unit like the Surgex has a lot of circuitry that prevents a clean signal from reaching the components. Compare that to a Furman. A Wiremold power strip has nothing internally to delay or colour the sound.

From the FWIW department, I use a balanced power conditioner that provides surge protection but can also provide enough power for transient spike demands with dynamic music. I have no degradation of sound plugging the amp into the conditioner. It has specific outlets for amplifiers. I suggest a bit more research.
