Вот интервью Стива Мккормака о сетевых шнурах а он для меня больший авторитет чем ........

PD: You are an advocate (at least a gentle one) of decent power cords for your products. Given we’ll never explain to everyone’s satisfaction why cords should make a difference, what are your thoughts on how the power cord impacts your products?

SM: I believe that everything we can do to improve the quality of the power driving our equipment is well worth the effort, and for me that definitely includes the AC cords. I have heard a lot of theories about why they should or shouldn’t have an effect, but the simple truth is that I hear significant differences among them. They have become an important part of my equipment mix, so I encourage others to experiment with them. As you know, I do not include an AC cord with my VRE-1B reference preamp because I do consider it an important part of the final result and I want my customers to reach their own conclusion about which is best for them. If I could be certain that a particular cord would give the best results in every situation, I would either include it or make a specific recommendation, but that’s the weird problem with all cables – you just can’t predict how they will behave from one system to the next. I suggest that people work on the basics of their AC power system first. Spending a few hundred bucks with your local electrician to have a dedicated AC feed installed goes a long way. Use “hospital grade” outlets at least (easy to get and not very expensive) and if you want to get more esoteric, fine. A relatively small investment here really pays-off in improved sonics and reduced noise (what we often call “blacker background”).

After that, experiment with some audiophile AC cords and see what you hear. Everyone gets to decide for themselves what works and what doesn’t, and how much they want to spend. Powerline conditioners fall into this category, but my suggestion is to do the basics first. If you can add a dedicated AC line to your audio system and find a power cord you really like, you may find a power conditioner unnecessary. On the other hand, if your situation does not allow you to add a dedicated line or improve the outlets, an AC conditioner may be helpful. In any event, your ears should tell you what works and what doesn’t.
