Well DeMagical disc arived in the post last night and I gave it a whirl.  Listened to a few tracks of a couple of CDs which I know well and rate and also same with the olde worlde black disc spinner.

Ran the DeMagic.  Its not as horrible sounding as I'd been led to believe - a sort of polyphonic test tone with a very obvious high frequency element and a sort of throbbing going on in the upper bass - in fact if you found it on some avant garde electronica album with a title like "Polyphonic Throb" or something equally pretentious, you probably wouldn't bat an eyelid - tho you might get bored   Anyway I digress.

Then I listened again.

Didn't make any difference at all so far as I could tell.

When this is all done, we're gonna need to set up a poll of some sort:

a)Made no difference

b)Made it better

c)Made it worse

d)I really like this band, when is their new album out

The results are looking interesting though.  The suggestion is that it does make a difference in some circumstances/some systems - presumably systems which are more susceptible to whatever it is this things supposed to fix - but not for most.  I'm still mystified how this could possibly work.  Having heard it I doubt its the "maybe it shakes your speakers cones about" theory.

Next up - Bob McCluckie - I'll PM you to remind - send me your address and its in the post.
