Ac cords or power conditioning first?

What is approach if you can't do dedicated lines. I live in a 1953 all stone house, running wire is impossible, (the walls are stone block).

Mlapenta,

If you can't run dedicated lines, I would go with the best power regenerator with battery backup you can afford. I can't say enough about the PurePower, and they have the science to back up their claims. Many like PS Audio as well.

FWIW if you have a wall that is out of common site areas you can run lines through the roof and down side outside of the wall and drill through the wall.... just a suggestion....

i dont have any exp. with other mfgs. but i started with a ps audio power director, then moved on to cords , most recently the perfect wave line, and ran that through a power port wall outlet. as a reformed cable doubter i can say now without a doubt that it does improve upon the sound. i will also note that i started out with pretty clean power to start with.hope this helps.

excuse me..what is the mean of "dedicated line".

Gmahler2u, dedicated line is one power source from your electrical panel directly to one outlet. Nothing else shares this line in the house. Look at the isolation transformers too. Hospital grade Tripp-Lite transformers. I have two dedicated lines but still use these coming off the two lines. Re-generators may be better but I could not afford to keep the Exact Power EP15 that was loaned to me. If I could not run dedicated lines and had to start all over it would be transformer or re-generator, Oyaide outlet and then power cord. The power conditoners I used dulled or closed the sound. The transfomers also have surge protection.
