Stupid Power Conditioner question but...

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?

Check out Audience, they are non-current limiting and provide excellent power conditioning.

Do you really have a 20-amp dedicated circuit? There are three things that rate the circuit at 20 amps: a 20-amp circuit breaker, a wire that handles 20-amps (#12 or #10) and a 20-amp receptacle.

A 20-amp receptacle (Nema 5-20) can accept both a 20-amp and 15-amp plug. A 15-amp receptacle (nema 5-15) can only accept a 15-amp plug. The 5-15 is the most common receptacles installed in houses. This limits your circuit to 15-amps and is the reason why the Panamax unit is rated at 15 amps (because it has a 15-amp power cord that only fits in 15-amp receptacles).

The difference in the receptacles is a 5-15 has the hot and neutral parallel to each other because the plug blades are parallel. The 5-20 has a "cross" in the neutral because the 20 amp plug has the hot and neutral perpendicular and the "cross’’ enables both the 15 and 20 amp plugs to be used.

If you buy a 20-amp power strip it will have a 20-amp cord and will not fit in a conventional 15-amp receptacle. You will have to replace it with a 5-20 receptacle and the electrician won't do it if the other two conditions are not met.
