Detail Magnifiers by Econotweek

The web site says you have to use them for a while, and then take them off, to hear how much they do. They say it is like having a heavy woolen Burka lifted from in front of your speakers.
All kidding aside they are RC networks which do have a positive effect on many speakers. The seller compares them directly to Walker Audio Valid Points.
I know people who have used them but for unexplained reasons take them off and sell them.

Mechans, Thanks for your comments.
So, far they have about 1 hour of playing time and they were quite cool when I installed them (directly from the packing box).
It did seen like they were getting better towards the end of that hour.
Tommorrow I will play them much longer.

A speaker "snubber". Essentially, a high pass spike filter that's supposed to absorb RFI/EMI as advertised. Don't think so. Behind a Pass X350.5. WTF?

Ngjockey, Please explain a little more...

Update: The Detail Magnifiers now have about 12 hours of playing time and already the sound is improving.

I don’t know why I am surprised though. Past experience has shown that Resistors, Capacitors, silver wire, silver spades all need some break in time. An when I first installed the Detail Magnifiers they were quite cool to the touch (straight from the packing box).

What I have at this stage is deeper richer tones in the vocals, extended clearer high frequencies and a more defined bass. The Soundstage is getting deeper and it seems to be progressing by the hour.

Even at this point they are keepers.
