I do believe that dedicated circuits will give a nice bang for the buck.
My amps and powered sub-woofer love being plugged directly into dedicated 20 amp circuits. After that, you want to isolate your digital
equipment from your analogue. IMO, this is why many people report hearing improvements after adding filtered power cords to digital equipment. Digital players will pollute your system. If you can provide a dedicated circuit for each of your components, you could get away without a filtered power cord on your digital components -- or AC conditioner [and ISOLATOR] in your system. But IMO, it is more cost effective and effficient to plug your amps and powered sub-woofer into 20 amp dedicated outlets and then plug an AC Conditioner and *ISOLATOR* into another dedicated 20 amp outlet and plug everything else into that. Make sure your AC conditioner also ISOLATES each component plugged into it. This keeps your digital from polluting your system, keeps your components isolated from each other, keeps noise from bad electricity out of your source components, keeps them from transmitting that noise to your amplifiers. I would start with dedicated circuits. Then, I would add something like a BP-2.5. I orginally bought the 3.5 with the idea that I would plug my amps into it. Since I've learned that my amps would rather be plugged directly into dedicated circuits, I probably could have been fine with the 2.5. But -- I still like having the 3.5. It is probably overkill, but then -- most people would say my whole system is overkill, so why split hairs?
