A single Z sleeve is not quite effective as running one per channel of course, but you gain about 90% of the gain of running a split z sleeve
Original design alternated ERS with brass shim stock. I find that using copper foil is significantly more effective and that less layers are needed. Mark originally would run three or four layer of ERS and then a the brass. I simply alternate the ERS and copper, with very good results. I run perhaps three to four layers

Thanks a Lot Stu, you're very helpfull!
On another subject i'm trying various place for your coal tweak and I can say that's an amazing one!!!
I have 400grs briquettes sticks I disposed on ac plugs, on opt and ht Coils, on spkr cables and every time this is a big improvement. Effects make me think about black discus (on top of xformers) but with better results! And for 3 euros coal...
But the best of all is you: I'm new on this forum and try to read everything you wrote for years!!! Lot of time to read but lot of years spared to access the audio graal!
I post many very weird non orthodox tweaks. Bu generally I try them out in various systems and use them for a while before posting.
The charcoal blew me away: results were totally unexpected. You can crush the briquettes to juggle the amount to get the right tonal balance.
one of my friends told me I missed the bot there. I should have placed a couple of briquettes in beautiful wooden box and sealed it , selling it for $300 a pair..... LOL!!!!
Just glad you're enjoying the tweaks. Wish I could go back to France. spent a week in Marseilles and a couple in Paris and thoroughly enjoyed my self. This was away back in 84....
I Stu,
Marseille is 80km far from my place (I'm living not far from Avignon)
If you travel once again in south france, tell me!
I'm looking for brass nickel plated plumbings but in France it seem there's no tubes for water service made like it... Each time it's zn plated.
I'll probably buy nickel foil I'll wrap around a red copper tube: hope it will work!
Check out American Ebay
There is a seller : hipp-modern-builders selling a lot of them. Average price about $6 but the postage is up there. If you buy a lot perhaps you can negotiate a lower shipping price. Be careful not to buy the plastic ones: you want the brass chrome plated (actually nickel) models.
There should be something available in the more boutique plumbing fixture stores as the tailpieces are usually visible, unless in a cabinet.
Good luck
Hi,Is it that?

MR French is very rusty but i do believe it is chromed, right. Probably is ok. Take a file when you get a sample and file the end to expose the base metal. should be brass
In North america 1 1/2 inch is standard diameter I have trouble finding 1 1/4 to slide into the 1 1/2 tubes

So I think I previous didnt't understand your whole design.... You mean you use 2 of this brass chrom tube to make one Sleeve?
And your french is not so rusty it's brass and chrom! By the way I didn't know that chrom meant nickel!
The more layers of mu metal the better the EMF isolation. Now the plating is basically pure nickel is a mumetal without the cryogenic treatment. SO rather than use mumetal ( expensive and you know I am cheap) I slide the 1 1/4 tailpiece inside a 1 1/2 one. You can use o rings to center the inner piece or washers.
While a single tailpiece works, two concentric ones work even better.
File the edges to base brass metal and essentially you make one tailpiece present a double layer of mumetal to the EMF . No extra cost, just a few minutes of work with a bastard file (yeah that's what they are called in the US)
Well Stu,
What you said about nickel (absorb magnetic fields) and brass or copper (reflect electric fields) made me understand why so many people say that they prefer not shielding theyr IC's: most of the time the shield is only a copper mesh with an aluminium foil and the lack in magnetic field absorbing must create bad things you hear as a veil...
So I think it would be a good idea to shield my IC's with that kind on brass chrome plated thing...
Is it right?
For sure it will clean and rinse electrons :)
Apologies for my bad english!
Your english is far better than my French
Yes the tailpieces will work superbly on IC's. The lower the signal level, the more the gin ( think Phono IC's)
Remember with any AC ( read signal)both a magnetic and electrical field are generated. Most cable shielding addresses the electrical field and ignore the magnetic.
The situation is more complex than shielding though. The magnetic field induced generates an electrical field across its surface too. That's why you need the copper foil layered on the tailpiece. Actually i forgot to mention that I use 3M copper tape to line the tailpiece before starting the layering of ERS, etc.
Doing this copper lining actually speeds up the magnetic field and adds dynamics and top end, as the nickel in inducing current will meet some resistance, which the copper relieves.
Key is low resistance: Hard to beat Mu metal magnetically and copper of course speaks for itself
a photo of a sleeve I made 10 inches long: one layer of ers but copper tape on the tailpiece and another over the ers
Hi Stu,When I look to the picture the inner of the original tailpiece is of brass
which seems to have carbon conductive paint scratches...kind of little carbon covering...
Audiocom who sells this product in UK says that the new ones don't use ers anymore...

Always skeptical I thought how could I try this only as a proof of concept or disproof of concept. So I took some spent toilet paper rolls and wrapped a single layer of copper foil around it. Then I used a pair of scissors and cut the roll longitudinally so I could easily slip over my ic's going out of my dac. Yes I'll be darned if it didn't clarify the upper mids to highs.
Use the tailpieces as the magnetic aspect is actually more important than the electrical induction. They are cheap enough, better than cable risers. if you ask me
Stu - I can find quite a lot of chrome plated brass tail pipes on ebay, but no nickel plated ones. Can you point us at any genuine nickel plated ones? Thanks.
Sigh: advertising rears it ugly head.
All chrome plate start off with a nickel base. It is what gives the object the shine.
Chrome is more of a clear coat, so to speak,(it ain't exactly clear) . The chrome plating is not as porous as the nickel and thus provides a layer of protection. Back in th 60's that was the buzz word: triple chrome plating: still see it for motorcycle parts: in reality simply a thicker chrome plating most times
Almost all so called "chrome" plating is only nickel. Real chrome adds a lot to the cost, but most people do not know the difference as it looks almost the same. Real chrome has a sort slight bluish tint t the finish.
Old Mac, Dyna gear all used only nickel plating which is why over time they do corrode, since the moisture will penetrate through the nickel, not having the protection of true chrome.
All the tailpieces i have seen are nickel ( unless they a plastic base, then it is aluminized)
I seems that the chrome plated pipes are nickel plated before.
So brass chrome plated would be nickel plated too!Stu do you confirm?

I have been using bags of charcoal strategically placed around my speakers and the effect is amazing in the bass. I leave the chacoal in the bags and place the bags in large plastic storage boxes to tidy up the whole thing and the bass and lower mids are amazing.You mention crushing the charcoal to affect the tonal balance. Can you say more about this? Without crushing the charcoal I get real strong bass. Does crushing the charcoal improve upper mids and highs?Here is a link to a comercial product from Acousticfields that uses charcoal.

Funny thing is activated charcoal sucks in my opinion.
Two much charcoal and the trebles get muted.
I break up the briquettes and since they are in a plastic bag anyway, I can adjust the amount of charcoal to get the desired tonal balance.
I wont debate the merits...I happen to like it. But when you break it up do you get less muted highs?
not really. in decreasing the amount of charcoal i get better highs in my system
