Another Next Best Tweak

This does work, and I noticed an improvement in sound. I used a larger (stronger) Neodymium Rare Earth magnet on the Transformer side in My amp. I had it on for two weeks and can say it is an noticeable improvement, compared to not having the Neodymium magnet.

But being the Audio tweaker that I am, I put a similar size Neodymium magnet on the other side of the outside chassis of my amp. What happen was the sound became much cleaner sounding. The over all sound was louder, especially voices. But in away I liked the sound , but something was missing in the fullness area. So I tried a smaller Neodymium magnet and everything snapped right in place.

The nice but to lean sound was gone. The fullness was back, but better than with the one Neodymium magnet on the Transformer side. Dynamics were better as was the bass. So this combo of different size Neodymium magnets works in my current system. Power amps are the only place I have tried the magnets.

I used the Neodymium magnets on both of my Emotiva UPA-1 mono-blocs amps with great success. I only used one Neodymium magnet on each mono-bloc near the transformer.

Wish I would have thought to try the two magnet combo on each mono amp before I sold them.

Thanks for the additional information. Jejaudio, are you saying that I can just place the magnet on the outside chassis cover?

Ozzy: Look at my system pictures. I just took some pictures of the Neodymium Magnets I use.

Yes you can place them on the outside chassis cover. I have posted a picture of a handful of the Neodymium Magnet that I have. They are all taken from computer Hard-Drives.

Some are larger than others, but they all are super strong, like you said. I have dozens of these Neodymium Magnets.

BTW you can cleanly break the Magnet from the steel plate by using two channel-locs pliers, and bending the steel back plate on each end to separate the glue holding the Neodymium Magnet. You will hear a slight pop

I like to leave the steel back-plate on, because the flat magnets are to much work to remove. But you can slide them on the chassis of your gear. I guess most would not want to do that for fear of scratching the equipment.

Jeaudio, Thank you for your response. I'm going to give it a try this evening on my Amp.

Back to my original post, and to respond to Rrog comments, I have taken the magnet's on and off the speaker cable as you suggested. The result???
Well, I'll be "dogg on" if there isn't more dynamics to the sound with the magnets.
Now, my speaker cables are DIY with only oversized Teflon tubing used as a dielectic so perhaps that is why the magnets seem to work so well.

Ozzy,
I have tried neodymium magnets on all components that have a transformer -- on the outside of the chassis. The results have been uniformly good -- as well as on the MPCs. There are forums that talk about how people magnets in their systems. If you look for these forums you may find some useful information.
