The fallacy of ac treatment


I see a lot of threads related to managing and tweaking the ac powerout end of electronic systems. Much has been said about dedicated wiring, termination and even the right kind of extension cords to use. I work for an electric utility; and that's the extent of my credibilty here. The majority of you will no doubt be far more erudite wrt music hardware. Just a thought, though: domestic ac distribution goes thus: power station-step up-city-step down-subdivision-final step down. As far as the utility is concerned, you and all your neigbours are collectively the load for the step down tranformer. Any inductance/capacitance created by your neigbour running motors/tubelights, etc is felt by the lot of you. Additionally, the voltage frequency will almost always move around a tolerance from 50hz as the whole country turns on the air, off the lights - changes all the time as peaker plants ramp up etc. Nothing can change that- the frequency of the grid supplying your city is the frequency in the mains at your house. So what's my point? Well only that how much difference can the last 10 feet of cabling, etc make when the other hundreds of miles are outside of your control? And more importantly, frequency is one of the most imp parameters for measuring electricity quality (your expensive hand-coiled toroids are entirely subject to the f in the primaries) and nothing other than running an f generator can shield you from that. Methinks all the improvements you see from ac cord treatments are pyschosomatic. But that's cool.

Onhwy61, I agree that power cords around US$250 are very adequate for most systems. As to the ones costing 5 times more, I agree I would not buy them on 'spec and would probably not even try them - without a credible recommendation. I have always found it interesting that the US scene seems to be over-hyped on cables, yet the British scene is the reverse. A good example was the recent TAS that recommended systems where some included cable recommendations that rivalled the cost of the components.

Early last summer I had 4 dedicated outlets put in for my stereo system and also a dedicated ground-- one ground system for the 4 outlets. It cost $850. for parts and installation by an electrician. After doing this, music in my system became bright and grainy. I learned from Redkiwi that a dedicated system WILL be excessively bright and grainy, as that is the "sound" of the stock AC cords. So I auditioned seven different power cords and ended up purchasing 4 Syn. Res. Master Couplers. The improvement in music quality with the HQ AC cords was dramatic. This change took a system that was nearly unlistenable to one that is highly enjoyable. I should add that the dedicated AC and ground system noticeably lowered the music's noise floor and was definitely worthwhile-- BUT it needed the good quality AC cords to complete the upgrade. I paid about $225.- $275. each for the SR M/Cs (a couple had to be special ordered, ie one w/ 20 amp IEC plug, and one with a right angle plug) and feel no need to even try the obscenely expensive PCs. I'm a believer in good quality AC, and good PCs are just a necessary part of a good system. Cheers. Craig
Garfish, I don't blame you for not wanting to pay a grand or two on a PC. I never thought I would either but I did. It was the best audio upgrade I have made in years.
Brulee; got to admit to being very curious about the high bucks Pcs, and if I can get a few "on trial", I'd like to hear them. Cheers. Craig.
Brulee REf the ps power plants. If they benefit from improved ac power cords then I would suggest the stock cord impedes the flow of current. It would be interesting to hard wire from the wall direct to the unit with a dedicated circuit to avoid any weak links. Have you by chance tried this. Sorry if I repeated this message but it did not transmit first time. Steve
