Thank you Clay, what´s your opinion about the W3NQN-7 filter?. Have you compared it to other filters or power conditioners?.
Juan,
I think any of the Array Solutions filters are likely a bargain, but I've only used the custom model, designed to operate at a higher frequency than normal audiophile filters.
The filter definitely improved the sound of my system when used between computer and AC, but I've not compared it head to head to other filters.
I also use Audience Adept AR1Ps (which I bought used, as I don't consider them great value when purchased new), in line with the Array Solutions box
I've also heard great things about PS Audio filters like the Ultimate Outlet and it's replacement the Duet, which is supposed to be even better. Note: I recently picked up a B stock Duet from Parts Connexion at a great price, but haven't listened to it yet.
These are the boxes I use for the computer side of the setup.
If money is no object, perhaps the Ayre LX-5e would be a consideration. Charles Hansen knows a thing or two about isolation & filtration.
Note: I never plug anything else into the same filter as a computer, or the same duplex, for that matter.
