recommendation on power conditioner for mc452

+1 for jwpstayman. 
A whole house surge protector would be the best way to go. They aren't very expensive (not counting installation), but will provide peace of mind.
Remember, these are sacrificial, so if you do get zapped, you need to replace the unit.
I just bought a couple of these, https://www.corepowertechnologies.com/
, but haven't gotten them yet. Lots of good feedback here on Agon.
You can call Mark and give him your needs. I am sure he will point you in the right direction.  Telephone – 720.317.9141

Need something for surge protection which doesn't take away from current. Also cleaning /conditioning not required.

Come with $10K insurance, If you don't like it, just remove it from the outlet!

^^^Contains chokes. How do you know it to be non-current limiting imhififan?

For $22.15, is it worth a try actually you can hear any different?
