Well I'll be darned! I read the below review (see link) and decided to give this a shot. Furutech NCF Clear Line AC Power Line Optimizer Review A skeptic gets his comeuppance. Review By Paul Schumann For $250, it didn't break the bank, unlike some of the other high priced power products. I do have a dedicated 20 amp line right to my main power box and a FIN outlet. My amp is plugged directly into the wall and my equipment goes to a fairly inexpensive power strip from Furmen, a PST-8. This device is a passive unit that simply plugs into a spare outlet on the strip. Easy as can be and even easier to pull it out for A/B comparisons. Does it work? LOL. Yes it does. Not only with audio, but with my video picture as well. Go figure. Going back and forth with it in and out, one can hear the differences. With it in (after a 24 hour break in), the soundstage gets deeper. Everyone seems to move back, and the ambiance cues are fleshed out with greater detail. Musical passages or voices that were somewhat forward and hard and now just as dynamic, but opened up on larger stage. Playing the same passage with the NCF out of the system collapses the soundstage to a somewhat flatter dimension. This was evident on my UK Abbey Road, MFSL Muddy Waters, and other darn good recordings. And as I mentioned, something was going on with my TV as well. My TV is older, and lately I've been noticing some "pixilation" on the screen. It's hard to describe, but it was there. Now, with this device plugged into my power strip, the pixilation went away after a brief warmup of the TV set. I haven't seen the picture this nice in quite a while. Wow, some visual evidence as well. All I can say is that for $250, this device is staying put in my system. As I said, it's so easy to do a comparison for yourself. Maybe someone who has already invested big bucks in AC conditioning won't hear a thing. But with my basic power strip, IT DID make a difference, and I just want to share that with you.
