Mixing Line Conditioning

I am using a Seakay Linerover parallel line conditioner (A box that plugs into an outlet and conditions the power of all the outlets on that circuit) that does not have surge capability.I bought a monster cable HTS1000 power strip for the surge capability only.It also has power conditioning circuits.Could the two different types of line conditioning actually be degrading the audio and video or can it help by using both kinds at once.
while their are exceptions , mixing line conditioners can definetly hurt, to many connections , cascading filters , its easy to over do it.
