Before we go any further on this subject I think it a good idea to learn a little bit about the man himself. From what I read head-fiers are under the impression that peter Belt is a snake oil merchant but that's not the case.
I received an absolutely whopping bundle of papers and articles from Mary Belt this morning and was quite stunned to learn that peter belt produced his own electrostatic headphones, orthodynamic low mass diaphragm headphones and a range of revolutionary light plastic film loudspeakers back in the 1960's, 70's and 80's.
He was at the forefront of the Hi-Fi scene and revolutionised the orthodynamic headphone market with his diaphragm consisting of a thin polyester film bonded to a thin foil of aluminium instead of the usual copper. Mary Belt even sent me one of the original diaphragms along with the bundle..... see picture:
I wish I could upload this bundle as it's packed with extremely interesting stuff and informative articles but to do so would take many mega bytes of space on my website!
Once I've finished fully reading this bundle I'll be more than happy to send it to genuinely interested parties as it goes toward explaing rainbow foil and much much more in depth.
Just to let you all know that Peter belt is not someone who's just arrived on the scene, he's been researching and designing Hi-Fi products (including headphones!!) since the 1960's so I think he knows a thing or two about Hi-Fi.
Certain people here have suggested that the rainbow foil be "measured" and that one persons opinion in not a good enough measurement.... well for me, I use my ears and they are a good enough measuring tool for me
The same can be said with everything... just because one person likes the sound of the sennheiser HD600's doesn't mean the next person will like them and no degree of "measuring" will change that.... only your own ears can decide and, considering you can a free sample of this stuff then why not use your own ears and give it a whirl?
I'm serious on the bundle and if anyone is interested I'll post it over once I have finished reading it. it contains some quite mind opening articles
In the meantime, some interesting discussions can be read at : http://groups.yahoo.com/group/PWB/
I just wanted you all to know that there's a lot more to Peter Belt than Rainbow foil.
An original PWB orthodynamic low mass diaphragm
I'll be reporting back on the rainbow foil shortly once I have fully evaluated it along with a helper who will be blindfolded on a chair with his head facing away from the CD player (seriously!) I've got about 22 rainbow strips left so I can try them out on a variety of objects as well as CD's. If it turns out they do nothing then the exercise will not have been wasted time as I've learn't a lot about another Hi-Fi manufacturer and have read some interesting stuff......... if it turns out that the rainbow foil does indeed work for me then that's an added bonus.
One way or the other, I'll report back with my honest impressions of the rainbow foil and I hope the other head-fiers who ordered a sample do likewise.. comments from those who have tried it, whether negative or positive, are a lot more useful than comments from people who have only seen pictures of it.
Subjective V objective... plausible V implausible..... science V magic...... whatever, I'm willing to let my ears be the final judge.
