Last year i bought the very excellent LessLoss Dynamic PowerFilter powercords. I use them them on my cd player (AMR cd 777), amp ( Musical Fidelity Nu-Vista pre and power) and on my Blue Circle power conditioner. My system is very transparant (Von Schweikert VR5 speakers) and these cords are the best i heard ever. And i heard and own a lot of different brands and types. But LessLoss decided to upgrade this cable for a Signature version, and this cord is even better! A grand combination of tube like smoothness with extended detail, openness, detail, bigger sound stage tighter bass and more color. A must have for everyone who wants the most of his system and far more interesting: wants to be toughed by the music. Adding the excellent service of Louis Motek makes it a very good offer i can recommend very much indeed!
