Stupid Power Conditioner question but...

@OP
+1. The whole house surge protector is the best way to safeguard against power surges, not only for your stereo equipment, but your computers, as well.
@erik_squires @jea48 ,
Always great advice.

“I would plug the amp directly into one of the receptacles of the dedicated 20 amp circuit’s duplex receptacle outlet”

Please don’t do this without installing surge protection at your main breaker box. 

Whole house OR Zero Surge plug in.

Well....

Whole house surge protectors usually have a rather high activation voltage. 350V or so and they take time to work. On the other hand they since they are close to the ground / neutral junction they have a good chance of working well vs. using MOV strips far from the panel.  I think every home owner should invest in them, they are relatively inexpensive and placed in the right spot, but best?  Not to my mind.

Zero Surge / Brickwall clamps under 200V and has no activation time.

The best solutions IMHO are a combination whole house + series mode protection, followed by whole house + Furman.

I think the OP did say he/she had a whole house surge protector in place.
already. If so, I think any downstream surge protection would be superfluous.

IMHO, putting an amp behind a surge protector that is not a whole house one is a potential way to diminish sound quality. And, especially so if you have a high output amplifier. So, considering my monoblocks put out more than 100wpc, is there any power conditioner/surge suppressor that will allow them to perform without limiting their performance?
