a while ago it was suggested to add magnets to black discs and see the result on a set of headphones. I got no result but gave it another try today. I have a set of small rare earth magnets from a Radio Shack closeout and set them into holes I had drilled into my Black Discs. I set them on my phono preamp and had one of those experiences where you go to listen and you think somethings broke because there is no sound at all ... till the music starts. ... so, that is what a black background is, hunh?
The phono preamp in play is a Yaqin MS-22B

unclestu, something like this?

Wherever you go there you are.
Weirdly while reading your response, Stu, I saw an ad on the very same page. Might be of interest to you.

cool site, what I like about it is that it ells you how the magnets are polarized: very important for me.
Now to scrape out another 10 hours a week for experimentation.....
sigh..............
unclestu, would you keep us up to speed on your experimentation?

Haven't played with magnets on BD stuff but have on other stuff. On MSA Kegs I like to sandwich the kegs with two copper sh=foil sheets on a MU metal foil disc.
This, placed on B+ leads from a power transformer, before the diode bridge) is one of the greatest and most cost effective tweaks I have employed. S/N floor drops dramatically giving a huge dynamics and fine detail.
I 've also employed the kegs on AC lines of my PLCS to similar effect and IMHE it pretty much blows away ALL the major contenders. I use the older Vans Evers and Tice units as my base, but believe me I have ried many others. Of course adding them on to the other PLC provides similar improvements but perhaps are quie so cost effective (I'm a cheapskate).
One of the craziest implementation of magnets is on the legs of metal equipment racks. Important caveat: do NOT do this on a rack holding a TT. The magnetic field induced will affect the cartridge and very negatively.
I use a ladder styled rack, custom built to hold my components and digital gear. I place a magnet, and even an el cheapo refrigerator magnet will work, on all the cross pieces of the rack.
Better detail and dynamics are the result. I've been too lazy to pull my gaussmeter to measure, but I believe the power transformers on your components are entering the metal ( usually ferrous) legs of the rack(note I haven't used an aluminum model). They are inducing a current which will permeate and rotate within the legs, particularly if all are interlocked. I believe the magnets limit the extent of their inductance, ad certainly I gain performance by placing magnets closer to the corner wher the power transformers are located.
Any some foood for thought and playing around.
