Dedicated line questions

Hi Korn and Craig. Craig has covered most of the points well. Note that if you put a dedicated AC in you will have to get good AC cords for ALL of your components. You need the AC cords to provide some common mode rejection, and you may even need to use a filter. Using standard cords with a dedicated AC can be excruciatingly bright and grainy. On the subject of breakers versus fuses - I have found the old style ceramic fuses to sound the best. Craig found the reverse was true, which could be a difference in the power supply, or could relate to Craig using a different style of fuse to the one I am using. Craig is right to emphasise the value of good grounding.

Hi Korn. Albertporter has covered the ground arrangement. I have found that the results vary. In one case we found a dramatic reduction in noise, and an improvement that was more significant than the dedicated AC feed. In another case we heard NO difference at all by putting a dedicated earth in. Don't risk getting the directionality wrong or you will be disappointed in the results of your efforts and investment. As Garfish suggests - get enough AC feeder cable to do the job and then just run it from your board through your house or outside (ie. not installed in the walls just yet) and listen to what it does. Then run it the other way. There will be a difference. I have found that one manufacturer's product sounds better when run in the same direction as the writing on the outer of the cable, while anothers' sounds better in the opposite direction to the writing. You have actually got quite a lot of useful information in the above posts if you read them carefully, and all of it gels with my experience. Beware that the end result will cause your system to become a lot more lively and will much more transparently reveal any problems in your components. I am sceptical at Audiowhore's suggestion that the PS Audio makes the AC feed irrelevant. I have not tried a PS Audio unit but the comments I have heard indicate to me that it suffers at least some of the problems of all filters - ie. that it is a trade-off between lower noise floor and compressed dynamics. With a dedicated AC feed and good power cords, I find the benefits of a filter are small and the downsides are unacceptable. When PS Audio have a 240V version I will give it a try.

Thanks Audaibnjad. I remain a sceptic since similar claims have always proven to be false (such as jitter elimination etc.), but I will see if I can get my hands on one to try.
