I don't have familiarity with any of the three models you (OP) mention. I'm using a Panamax MR4300. It's in the same price range as the other pieces mentioned. Panamax offers a monetary guarantee more than enough to fully reimburse the owner should anything happen to your equipment as a result of a surge.
Surge Protector - Brick Wall/Zero Surge vs SurgeX
I am planning to buy a Surge Protector for my audio equipment. I have shortlisted the following:
Brick Wall PW8R15AUD ($259.00)
Zero Surge 8R15T-I ($286.00)
SurgeX SA1810 ($355.00)
I have heard that the Brick Wall and Zero Surge are clones and they claim to have isolated (duplex) receptacles to prevent interference and cross-talk. SurgeX claims to have better filtering.
Do they have any detrimental effect on sound? Has anyone heard them and compared them?
