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?

Hello all that are reading this....  I am the President of Zero Surge.  I came on this old post to clear up two points. 

1. Rudy Harford (our founder) is the originator and inventor of both forms of series mode technology that is used by us, Brick Wall, and Surge X.  Don't believe me? Read the patents.

2. We are not offering a new customer discount at this time.  New customer discounts make sense when there are going to be many repeat purchases but our products will outlast all of us.  It is more likely than not that this will be the only purchase you need for your audio equipment.  We make all of our products in our Frenchtown, NJ facility and if you want us to keep Americans employed (I sure do) then we need to keep the prices where they are. 

Unlike most companies these days when you call us, you will be greeted by someone who knows our products well and have the ability to explain our technology until you are comfortable with your decision.  We performance test our products.  There are no other surge protection technologies that can say that.  An MOV company can't send surges to their products during production or it will degrade their life.  Since our products do not degrade with use, we can make sure that everything is working well before we ship out our products. 

To this day, we receive emails and posts on other social media telling us how their sound systems have improved sound quality using our products.  One recent Facebook post even said that he didn't have to purchase upgraded cables because the sound was so good when he plugged in his turntable into our product!

Thank you all for the loyal fans! - Jim
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.
I have the Brickwall since 2005. But the Zero Surge 8R15T-I looks so similar. Either of them should work in a nice system.
Looks like OP is not active on these forums anymore.
Thread resurrection! I've used the Brick Wall for a dozen years or so and wouldn't hesitate to purchase another if need be.
Panamax uses MOVs so they will wear out and eventually stop protecting. That is why they have to offer replacement money (which is likely secondary to you having to file a claim with your home owner's insurance first and pay that deductible).  There is no way to know when it will fail.
