a signature on the main wire bundle, and infinities on the main breaker, circuit breaker and then possibly an infinity on an outlet.

Thoughts?

I got my Signature filters after I had installed the Infinity versions in my breaker panel, so I don't know whether the Signature is better than the Infinity at the incoming wires or those going to the audio outlets. Trying one of each is the best approach.

You will need to decide whether you want to take the cover plate off the breaker panel to install the filters. It would be more realistic to replace the cover plate for evaluation than to leave it off. In my case there is a utility company seal on the part of the panel where the wires come in to the meter, so I put a filter instead across the wires that go into the main breakers.

I have one of each type of filter on top of my Wadia. Adding a Signature to the Infinity improved performance at this location. I've also installed Infinity filters on the satellite receiver/DVR and at the power filter box for that cluster of video gear. As bartc said, there are outlets where the filters make no discernible difference, so it is possible to go overboard with these things.

I believe these filters work well in conjunction with parallel (line-to-neutral) filters. I don't know how much effect they have by themselves.

  Hi Al,
  
  I don't see a "Signature filters" on the product list at the Alan's site... Is that a new product that we can expect?

    Alan is evaluating sonic results. Contact him for more information.

I have only the original 1, but some observations. When I moved mine around, the most profound effect was with the first one, and with that on the specific breaker whence my audio is fed.
When we moved that one around Al's house, I liked the same position there, but he prefered either the main bundle or the audio room outlet.
So it's clear to me that those 3 places are the strongest impact.
We did find that one on the transformer (over the case) on his CDP gave a nice, but more subtle improvement. It works there on mine similarly.
So I can safely say that one is fantastic, those 4 spots are continued improvements. This was pretty much Alan's original advice, as I recall.
Al has many more all over the place, but we did find that every outlet was not effective in his home, so there are limits, less on the number than the specific location and its relation to EMI perhaps more than RFI.
It appears that Alan periodically announces a free extra deal on an order of 4 CBFs. If you can handle the cost of the 4 and wait for the deal, you get one extra then to play with as well. Not bad!
