Your post makes pretty hard to figure out what you are asking. I recomend setting up your new system before buying anything. See if you still have issues, which is hard to comment on because your question is so non-specific.
I have a Panamax 4300 which helps clean up broadcast tv and FM reception(antenna filter) in a remote location with weak signals. Tripplite is recomended as affordable professional grade surge protection by some pros. In my understanding the whole line conditioning issue is largely dismissed by experts in most circumstances.
If you have particular circumstances that would create problems I suggest you spell them out. If you expect some kind of audio magic in general through line conditioning I think you are about to waste your money.
