Finished it yesterday and been listening to it in the solid state 2ch/HT system for about 8 hours on and off.
I bought the magnets off ebay, and boy are they strong. I used the Leviton plugs from Home Depot, mostly because the spacing between the wire inlets are further apart and lines up better with the magnets.
The Rain Bird funny pipe tubing I had is a bit thicker than the standard, so putting three together wasn't a easy fit into the 11/2 inch pvc, so I used a piece of radiator hose from Auto Zone. This made a nice easy fit for the magnets in the funny pipes.
I used the largest nails that would fit in the plug after enlarging the holes a bit and some filing on the nails. I also left the heads sticking up to make more contact with the magnets.
The magnets are so strong that they practically suck the plug into the hose with them.
With the rear open, I could check continuity with my meter, then I just plug the holes with some little round feet I found in my grommet box.
It's not that pretty, but I could just put a nice big heat shrink over it.
So that's it, as for the difference it makes in the system, I am still waiting to hear any. I have it plugged into the spare receptacle at the wall that feeds the whole system, and I can't honestly say I hear any difference yet.
Maybe it's system dependent, or so subtle I can't hear it, but you will all have to try for yourself.
Maybe it's the type of surge protector you have downstream that blocks the effect, I am using isolation transformers. Maybe if I plug it into one of the outlets in the protector itself . Who knows, but I don't expect much.
Well I certainly don't hear anything negative either , so I will keep it there for a while, then try it in the tube system.
Follow Ups:
I have rebuilt the ones I made so I can open them and switch the polarity of the magnets and test the results in sound. However I still plan more experimentation.After many experiments, my results on my system are:
1. Magnets all need to be in the same direction of polarity.
2. The south pole end is the contact end.
3. On my system, these rules are a must.The magnets will be very difficult to keep aligned as the poles of same likeness will be repulsed from each other and will want to push each other out to it's opposing pole.
To find the north pointing end of the magnet, tie a thin string in the middle of the magnet and let it float. The north end will point to the earth's magnetic North. Then mark with a marker or scratch tool the different poles. Once one is identified you can just match it up to the remaining.
Same poles are repulsed. Opposite poles are attracted.Some interesting traits of magnets and metals are.
1. Stainless steel: has very low magnetism, depending on the mixture of metals.
2: Copper is non magnetic and in fact is almost the opposite of magnetism.
And exhibits a repulsion of magnets.
A fun experiment is to take a 1/2" tube of copper pipe and drop one of these magnets down it. See what happens. Don't ask me. Go look on U tube.

I like the idea of using the radiator hose. I use to have a few laying around when I owned American cars but that was 30 years ago.
After plugging in, I let the system run at low volume for a day or two before I did any serious listening.
I'm working on the RCA version now, between all my other projects.
Thanks for posting. :)
Any update?
Well, it's been in the system for five days, and I have noticed a improvement in the bass. It's a bit deeper and more defined, and a sense of ease to the music flow.
My plan is to give it time to let me adjust to it being in the system, then removing it to see what difference there is.
I think I will stick to just one per system however, because as the late Duster noted about a similar product, creating too many magnetic fields may be undesirable.
I would respectfully disagree with Duster's statement. To my knowledge he did not experiment with magnets in this way, so I would take that as anecdotal evidence. The main thing is to use your ears, see what they tell you. In my case I had magnets (thru not on) connected to power cords, speaker wire, IC's, and wall sockets--it was too much of a good thing. I still have a number of magnet/connections in my system, the good thing is that you can easily remove. Good luck!
Spot on. Even one genuine High Fidelity device will barely move the needle. As my friend has noted, you have get 4 or 5 in action to hear a substantial effect. Plus this also assumes the "clones" can match the actual HF plug-ins in performance.
What exactly is in the HF plug-ins, is it just the magnets?
Yes, as far as I can determine.
Sorry, again I disagree. I bought two of the MC-0.5's thinking I would send them back. With just two in the system-huge difference to my ears, I did not send them back. YMMV!
No need to be sorry. Different systems, different ears, different results....his sweet spot remains at 4 devices. With all that said and to further confuse, another friend sold all his HF devices a few years back, (and he had over ten) because he felt the Add-Powr plug-ins were more effective. So when it comes to tweaks, there seem to be no hard, fast rules.
I think you'll find many have had to use more than one unit to get a noticeable effect. Now maybe someone who has experimented with both DIY versions and the real thing (High Fidelity) could chime in.
Un-believable.
If you're truly interested, post your comments to folks who own and have actual experience with the High Fidelity devices. (or clones they've fabricated) Or better yet, info@highfidelitycables.com
I don't own/have any. I've just been relaying the experience my friend has had with said HF devices. No horse in the race here.
I use and own both (mentioned in a previous post) and yes, to my ears there can be an overload somewhere around 4 devices. Not sure how Ric Schultz does it with his huge magnets--avoiding over saturation.
For simplicity as well as safety's sake, I recommend using the rca method I described in an earlier post. I have one set plugged into my zen mini, as well as two unused inputs on my integrated amp.
One device is sufficient, but as in all things audio you need 1) sensitive ears and 2) sensitive equipment. The first time I got my High Fidelity adapters, I was ready to send them back, it does take a while for the magnets to break in.
Also, as I said, if the sound is diffuse, reverse the magnets. BTW, I own a pair of the older rca adapters by High Fidelity. Upon notifying them about one being iffy (not making a connection some of the time) they sent me the upgraded version--FREE! (worth about $500!!!) Thanks Ric! Great customer service!
Quick follow up. I just reached out to friend who I remembered having about 5 of the original High Fidelity devices. He said (and this in regard to his system) that the sweet spot was 4 devices plugged in as close as possible to his main system. Plus on that same circuit of course. A 5th device didn't seem to further enhance. One opinion, one system....so YMMV.
