Is this for real?


After flipping through the latest Musical Direct Catalog last night I saw some "system disc" products. Prices ranges from $19.99 to $109.99. These discs are suppose to send some sort of demagnetizing frequencies to clean out your system (speakers, components, and cables).

Has anyone tried these products and do the work? I wonder what will they think of next?

It is good to be skeptical. Cardas deas have a good ear though. If there was no difference/positive sonic impact, he would not be selling of have his name attached to this disc. I was skeptical at first, but I figured that for $20, it is worth a shot. Additionally, Ayre would not be promoting this disc if they did not think it had a positive sonic impact on performance as well.

My friend Joe in Tennesee said his top of the line Denon/ Paradigm Reference 100 home theater was lackluster in sound and " missing something" As I was on my way down, I said I would bring something that might help him out. I took my Sheffield Labs MDMS system conditioning and degaussing cd. After initial listening, we popped in the cd and left the room as the " magnetic domain matrix signals "did their job on the system and not our ears. Afterwards, he was amazed at the results, which were basically a cleaned up,i.e. more detail out of blacker less muddy background livelier as a result sound. He wanted one immediately and I referred him to Music Direct as they have a degaussing cd for $20 or so,and I haven't seen a Sheffield for sale for a number of years. I run it on my system every week or so and have always found it to be beneficial, to the point where I find myself thinking " Ok, something is wrong here. Oh yeah, get the cd." $100? If mine breaks and there isn't something available that's effective for $25 or so, I would do it. Don't know why or how it works. The vinyl version works as well, in my opinion. Have fun.- Gary
I also have the XLO disc and it has been stored without any use for the last few years. After seeing this thread I sought it out and put the system through the test tones, etc. After using the so-called demagnetizing sweeps I put on a CD and low and behold the highs were clear and precise. I recently thought I might need an EQ to fine tune them and bring them out more but now I don't think I do. Sounds really improved. It will stay out front and in regular use. I was sceptical also and just forgot I had it. Thanks for the post.
Is an engineer out there somewhere who could explain just how a test tone can "demagnatize" copper? If the explaination is feasable I would be a believer.
