Black Discus - Free Sample Alert


I recently requested a free sample of Mad Scientist Audio's black discus tweaks.
They arrived from New Zealand in a week! I was rather hoping that they would not work since cash for tweaking is tight, but, alas, they were remarkably effective in doing what they claim to do. The pucks were placed on the positive speaker outputs of the amps and were held in place with a dab of blu-tac. There was an immediate increase in apparent soundstage and the perceived 'air' around the instruments. I also felt that some low level details were more clearly resolved. I have no idea how it works. The web site has some info, but the fact is that it did work for me. Now I just have to figure out how to rob the cash from the budget to fund getting the full on product. As a side note, Mad Scientist states that the samples are a scaled down version of the actual product to facilitate mailing via letter post to hold down costs. That seems reasonable to me and I'm hoping for a greater result when the real deal Black Discus products arrive. I'll post a follow up, then. In the mean time, order free samples at your wallet's risk.

I requested a sample as well. Thanks for the heads up. I'll post my results here too once I receive the tweak.
I got mine yesterday and will report back later this weekend. I'm looking forward to see if this free version of the tweak is effective enough to warrant getting the big boy version.

I've yet to see or hear of someone who's willing to give out free samples until now so my curiousity is peaked.

All the best,

Just ordered my free sample.
Will also report back with my impressions.

This is the hardest thing I've had to write about. It's made me doubt, for the first time, as to whether I'm susceptible to placebo. Being consistent in my preference with the Black Discus in place I'm inclined to believe it works for the better but there will be those who say I'm imagining things.

Sitting down to what at first appeared to be easy enough to do (they go on and off quickly and easily), differences, or lack of differences should be easily observable. They weren't. The effects were all too subtle for me to reliably say one way or the other. It was only when sitting off axis, at my iMac that I really enjoyed the sound. It was more analogue in nature, more relaxed, yet it lost nothing in the way of detail.

Imagine being able to shift the focus on a lens of a camera. All the detail is still there but the equivalent of a tonal shift of the music occurs. A kind of glassy, leading edge is toned down ever so slightly allowing the balance of the note, or music, to rise up ever so slightly.

This is not to say that some kind of digital artifact is being negated. I've had bigger tonal shifts that amounted to actual smearing with ICs, SCs, and PCs. This is a different animal we're dealing with here. It could be that there is no actual digital glare in the actual signal (freeing the medium from most of the blame) but rather, technology catching up to the way it should be properly transmitted, adding further to the debate about cables being all they can be.

I don't know how it's done. In my system the results were subtle but welcomed. An ease of presentation leading to a better balance making it seem less digital and more analogue could only be noticed while not paying serious attention to it leads me to believe that something is at work here. I've never experienced listener fatigue with my system but this seems to be a more relaxed version of what I thought was fine to begin with.

I've yet to experiment with more recordings and may even change my mind about the discs efficacy or I might go and order one of the bigger versions to see if they have a more pronounced effect. This one's a puzzler.

All the best,
Nonoise
