Are these a decent upgrade to make. Anybody have any experience with something like a Nordost QV2 or something like it?

Depends on the rest of your system? What are you using right now?

Sim audio integrated, clearaudio table, b&w speakers with all nordost cables and a ps audio power plant. Just wondering of they're worth $350 a piece??

Don't you already have the same topic going already?

That depends on who you ask.

I have not used the Nordost, but I have tried the PS Audio things with the "blinky" lights. I could not really tell the difference. Given you have a PS Audio conditioner, I would say that you would be better off spending the money getting a dedicated 20 amp line, along with isolated ground for your system, IMO.

I heard a difference when I listened to the Nordost demo at Taves. Made poorly recorded music sound a lot smoother and palatable. Not sure if it also changes the sound of well recorded music.
If a lot of your cd's sound harsh or are otherwise not good. Then this product is well worth the money.

I have never tried one but I stay clear of device ads that have a bunch of mumbo jumbo, and hocus pocus that will make your system sound better.

“introducing a carefully calculated range of pulsed frequencies, clocked from the original 50 or 60Hz waveform” why not show me the AC signal before, and after.

“mechanically tuned high-tech housing” tuned to what, and the benefit is?

The “mechanically tuned carbon fiber housing” must make a huge sonic difference, I am sure…

Why not try one, because no one can prove that you can or can't hear a difference....

That sure looks like a capacitor in a fancy enclosure to me. If it is it will work, though there are far cheaper ways to do the same thing. A bunch of us are using a $5 capacitor to do the same thing and it is amazing how well it works. You can do a search for "caveman power tricks" under the forums.

Gotta say the bafflegab descriptions they use are annoying. How much are they asking for that capacitor in a box?

Looks like $350.00 in Canada.

Wow, that is some crazy marked up price. I am electrical engineer, so I can decipher the garbly gook. All it says is that it is a high frequency filter. The thing about the “introducing a carefully calculated range of pulsed frequencies, clocked from the original 50 or 60Hz waveform” has to do with your power company's generation and nothing at all to do with this capacitor in a box.

So what is it worth? However much the plug and capacitor cost. Thats all. If your paying full retail on audiofool parts I would say $40 on the upside. There are so many products that use a simple, quality capacitor between hot an neutral as power conditioner. The famous shunyata hydra does this with capacitors worth about $3 each. I actually have a capacitor installed directly behind an audiofool outlet in the box, in the wall. i couldn't source the same one as the hydra, so I went a bit upmarket and spent an entire $5. That said it is amazing how well this works, the description they give for results is pretty accurate. I tried the capacitor right before the power cord and as the power enters the unit; it works much better right before the power cord for some reason.

I'll trade you my capacitor for your power plant. I'll even make up a nice box for it. Not sure what tune I should hum while I make it, but I'll make sure its a nice one. (I think they are just saying the resonant frequency of the box is well below that of being able to interfere with the capacitor- but so is plastic)

Will C1 do the same thing?

Doesn't Blue Circle make something similar to the Nordost ? It doesn't have the nice carbon fiber housing but it cost a third of the price.

When I see a device that looks like it was made in someone’s garage, regardless of how well it worked I would pass...
