Ok....These tweaks work!
I've had these for a while now....about two months I'd say. After they arrived after a second request, I stuck them on the + post on my power amp and didn't really notice a change. But I must admit, I wasn't really paying attention as I before hand wrote them off as mere snake oil. (sorry JoeESP90) After they had been in place for a few days, I removed them from the post as I was doing some moving around. Afterwards I took a weeks vacation, so I was visiting in anther state. Upon return, the Black Discus never entered my mind, until a few days ago. So as music was playing on the rig, I stuck them on the + post of power amp and sat in the sweet spot...playing on the iPad...not really expecting, nor looking for any effect. After about a minute, I noticed something in the sound of the music. I heard the music changing! The normal flow of the sound was like being interrupted...some sort of disturbance to the flow of the song...as subtle as it was. I kidd you not...it was faint and sort of mysterious to me....but it was subtle in effect as it was doing something right before my hearing. I continued to listen and noticed there was a suck out. Before this, my system sounded fantastic, but a system can always be improved upon. The suck out I heard was noise I never even knew was there! How do I know???? Because all of a sudden I had a blacker back ground! I was like....Dang! What the heck just happened! I continued to listen and started noticing things like rig has better focus....better detail....bass has greater punch....mids became richer and pronounced ....and overall staging and depth was also stronger. I assume because of the blacker back ground, it seemed to enhance everything else.
Now If some of you have not experienced this, I have no explanation why not. I've read through these posting and a lot of you are on record at least as saying its doing something. I dont know if how resolving a system has to be, has anything to do with it. Every thing I mentioned above, my system was doing already, but I do feel the blacker back ground from the Black Discus has enhanced what was already there.
Call me crazy...say its all in my head, but if so, what is in my head has me on cloud 9! It's my conclusion.....the "Mad Scientist" have hit a home run! If you believe you have a good resolving system, and have a trained audio hobbyist ear, go for the free samples and sit and listen.
From the experience I've had over the past few day with this "free tweak" I will be ordering the paid tweak they offer.
Happy listening fellas!
