Is this for real?

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
