Audiophile Surge Suppressor (and nothing else)

@whart +1 on ZeroSurge. Similarly Brickwall or SurgeX

@zlone  You're correct even if you have whole home surge protection (I do) the electricians still advise other surge protection at the equipment.  I've had lightning strikes powerful enough to take out the whole home suppressor at the panel 3 times, though it did its job preventing any damage to the panel or otherwise.

check out Tripp Lite isobar has only noise canceling 

I second Trpplite. I've used their surge suppressors for years, after a whole-house unit at the breaker box. Make sure to follow through on your excellent idea of metal boxes, because T sells both metal and plastic.

ALL electronics in my house are protected by Tripplite or an isolation transformer. Tens of thousands of $ protected by some hundreds of $. Makes sense to me.

@zlone call Jason at the cable company. Ask about the wireworld matrix 2 power strip. 

Brick wall  , they used to be class B in stereophile recommended components.
