TBC: If it doesn't have a UL listing as a surge protector (I think that's UL 1449) you can't rely on any conditioner to have any surge protection capabilities at all.
Several high end conditioners don't even mention surge protection, for good reason! Trying to get as close to the transformer outside your home also make for direct connections of your equipment to the noise and surge. The last thing I want is a perfect conductor between my gear and the outside power, but so many invest in trying to get just that.
