Audio System Enhancer

Rega-BRIO-R.jpg
 
First off I have my doubts. I just emailed for free pair. If I don't hear a difference what am I out? Time will tell.
 
I have received 8 total of the Black Discus so far. I am only using 4 of them right now. On my Exposure amp I have one stuck to the top of the power transformer and one each on the positive speaker leads. Also one attached to the inlet power plug on my Bifrost DAC. I think that is the most I want to use at this time? I tried using all 8 of the Discus at once and found that too many of them suck some of the life out of the system. So only use these things sparingly.
 
OK, need to do this update!

Received replacements for the can opener size ones that went to an old address (thanks Kay) and another set of samples.

Now, i placed the retail ones on the positives of the speaker outputs on my amp (valve) and the samples stacked on the power plug at the output of my phono stage, NOW before I had an issue with the transformer buzzing in the phono stage, clearly audible from the seated position during silent passages.....was annoying as hell.

Guess what, no more buzzing transformer! not even with my ear 6" from it!

These definitely do something and definitely there is no placebo at work here.
 
OK, the buzz is still there at different times from the transformer, but reduced a lot, and some hum from the speakers i was trying to address, and did to some degree is less also.
 
Hmm...wouldn't the pins be orientated different in the US, and they might not like a constant 250v like I have.

I still don't know what actually is causing the buzz, could be DC on the mains from switching PS and inverters from various sources like solar power systems, as this will cause a buzz in the transformer.

Will be loaning a DC blocking unit in the near future to test this aspect.

This was more an interesting observation with the discus in this position in my system, it wasn't expected......but now you have showed me these I might look for similar that are compatible with our mains plugs and voltage levels here :thmbsp:
 
OK, they are rated as such

Voltage Rating: 100-250 VAC, 50/60Hz
Plug Styles: North America (NEMA)/Europe (SCHUKO)Voltage Rating: 100-250 VAC, 50/60Hz
Plug Styles: North America (NEMA)/Europe (SCHUKO)

They would be getting a constant voltage at there max limit, maybe a tad less at times, maybe a tad more at others, and not compatible plugs.

I'll see if I can find something like them.
 
OK, I'm over obsessing on that buzzing transformer, so moved the samples to the positive sockets on the phono, and the can opener type are still making a nice difference on the speaker binding posts on my amp :)
 
Best thing

Oh my god. . .they have the best explanations ever ! VERY, VERY FUNNY !

One of the 8 explanations.

"The Alien Technology Explanation : While I was walking my dog one night, I came across a UFO that had broken down. I helped the aliens "change their space tire" and before they left, they asked what they could do...I said that if they knew any cool ways to make my sound better..and the result is BlackDiscus"

Pretty funny. I suppose it could be true. :scratch2:

BTW, is there any consensus from those who hear a difference when using these as to the best placement for them. So far I haven't heard anything so where are you sticking them.

[I know what some of you are probably thinking. Don't say it.] :no::nono::D

When I had my original samples, I had them on the positives or the speaker terminals of my amp, now with the retail ones I have them in that position also, the retail ones are more obvious to discern.
The other pair (samples ) I have only just placed on the positives of the RCAs of the phono stage, but I haven't really been listening for more since.

Must have a listen over the next few days with those ones on and off.

I have all tube amp and also phono, and both are low part count relative to what most are...if that makes any difference.
