I did most of them at one time.

Mapleshade recommends trying one at a time. I did not have time for that. I wanted to just enjoy the sound. I did not want spend what listening time I have trying to figure out if I hear a difference.

I rearranged my systems, had the brass lying around, and decided to use them.

I was inspired by the brass screws in your amp, and the fact that the current production has a heavier plate.

Yah, I have a bit of a love affair with brass myself. I upgrade Carver C9 units. This includes a great paint job and brass screws, besides the circuit upgrades. I just think that brass looks classy, and is worth the cost. FWIW, Lee Valley sells brass discs that are intended for tracing. I have used them for anything but that. And they are relatively inexpensive.

As stated, I am reporting on the effects of the 'Mad Scientist' Black Discus in my system. First of all, I haven't done that much listening since yesterday, when the shipment arrived. My initial listening has first been with the samples that were sent, and I did in fact, hear a distinct difference in the presentation of the music. This  involved mostly the bass and treble. Treble being less sibilant, and 'digital', and bass being a bit more defined.
So now that the purchased discs have a arrived, I can only hear a difference, whatever that might be. More specifically, the two areas touched are the bass and treble. And again, much to the same results. Having said that, I think that there is a line not to cross when it comes to devices such as these. I am already thinking that a little is good, but more, not so much. This may be premature, and I will add comments to this as it develops. I suspect that certain recordings are more in need of these effects than others. Fortunately, I finally have a system that can bear out the differences made.

 This is not a conclusion, but rather an update for my experience with the discs. I have used these for a short time now, and though I appreciate their effect, I am still of the opinion that one or two of these devices is adequate for my system. I do however, have a new CD player on the way from Emotiva. This may change my experience with these discs. I actually hope that it does not. If the new player sounds better with them, then it might cast a shadow on my expectations of the new player. I will keep an open mind and post my experience at a later date.

Interesting!

You know, it will be interesting to see if the discs improve your new player. That might be because the player is more revealing? So it could mean that it's a better player?

Isn't this crazy hobby maddening sometimes!?

Well, I am doing things a bit backwards. I have placed the disc on the new player's power cord. I am using a Pangea 14-SE, 1/2 meter cord. What I am noticing immediately, is the background detail in music that I knew was there, but now is separated into more specific instruments, or ambience, or whatever it is that was homoginized before.

 Here is a little update that might be helpful to those that want stepped attenuators for the Rachel. In my experience, the stepped attens were not the best answer. Two reasons are that first the model that I use has only 21 steps. That is too coarse for fine adjustment in my opinion. Next is the fact that the model that I used seems to have some issues with balance between the two controls. I have seriously looked into this, and realize that it could be a different problem all together. Maybe the input tubes or something. I have on order a set of volume controls made by TDK. It will be good to have something with infinite adjustment. To be clear, the stepped volume controls on the amp were installed by me and not Decware. They were Ebay specials. I will know a lot more when the new controls arrive.

The TDK volume controls came in today. Maybe I can find the time to install them soon.
 Here is a bit of truth the statement "There is no free lunch". Remember a bit back, I was talking about a BSC circuit (baffle step correction) that I was using for the ZOB speakers? Well, there is, of course, an insertion loss of about 3db when using the circuit. At the moment, I am running Rachel near top speed. I didn't seem to be getting the drive that I wanted. On top of this, one set of interconnect cables was 2 meters from the CD player to the BSC circuit, and then an additional meter from the circuit to the amp. Lets just say that things weren't sounding like they did before. It didn't occur to me at the time that I was cutting off my nose to spite my face. Taking these two things out helped regain the sound that I was missing, but wait, yah, there's more. Because I can't leave anything alone, the output RCA jacks in the back of the new CD player are not reliable. What I mean is that i plug in and unplug connections far more often than the regular guy, so these connectors have loosened up quite a bit. No problem folks, I just got some new RCA jacks from Manley that are pretty beefy, so there is something else to make time for. You know damned well that the original RCA jacks are circuit board mounted, meaning more effort than Decware stuff to change something out.

This Might be a conclusion,,,we'll see. Ok, I installed the TDK pots today, the comparison is that between them and the ladder style stepped attenuators, I will never look back. Something just wasn't quite right with old attenuators, and I will never know. Now these TDK pots are not only more revealing (I thought that I would NEVER be the guy to say something like that about a volume control!), they have physical smoothness to their operation that reminds me very much of video tripods that have fluid damping. These things turn easily and even feel elegant to the action that they have. The sound is no comparison to the old ones, since the old ones even seemed to vary in resistance or something. Drove me nutty.
 Interestingly, I didn't have to change out the RCA jacks in my CD player because they also have a balanced output. The easy solution to this was to use quality adapters from balance to single ended right on the back of the CD player. Dodged a bullet there man.
