Let's please try to move beyond credentials, shall we? It's a stupid discussion to try to out credential each other in my opinion. Besides if memory serves it's actually you who doesn't have any credentials, not counting your GED. See the irony? Search the archives for when I revealed by credentials to Ron, you know, right here on Stereophile Forum. Have you given any more thought about where you're going to go for vacation?

Geoff Kait
Machina Dynamica

From what I have seen Costin, Ron, ChrisS, Catch22, Allen, Toledo and many others here have credentials and are able to share in the music just fine.

Concerning your credentials geoff, you have created your credentials here http://www.bing.com/search?q=geoff+kait+fraud&pc=Z161&form=ZGAIDF&install_date=20111120&iesrc=IE-SearchBox If you have another search engine to display instead let us know.

Why anyone would want to out credential you would seem a little odd to me. I have no idea why anyone would want to be known for the same credentials you have in this hobby.

I also don't see any problem with moving beyond, but you see geoff you don't have a stereo system to work with so when it comes to doing, we have to ask what you base things on. Even so we have given you every courtesy to share your opinion and that's how we ended back onto the subject of your credibility.

It's kinda like this geoff. Listeners ask you what you experience when you do this or that and you have nothing to share cause you haven't had a stereo for over 8 years, and about that stereo you did have you said "never looking back". You point to a list of products, and start to tell stories but they lead to you either saying you weren't serious about the topic, you weren't anything more than a dealer, have no forum after saying you had, and you end up saying "it's all a mystery". You pick on other forums like TuneLand yet say you have never been there. You pick on peoples schooling yet haven't taken a class since the mid 70's.

Why wouldn't someone ask about your credentials, or even why are you here?

Others might want to talk to you about Mu-metal or cork, but it's not like your batting a zero, you haven't even stepped up to the plate in many years, if at all. Sorry but you haven't shown that you have been serious about any part of this hobby except for used portable cassette players that we can pick up by the scores at any goodwill or thrift store. OOPs I stand corrected, you said you weren't even serious about them.

So I guess we're back to credentials unless you can wiki your way out or go buy a cheap stereo somewhere and join the hobby.

Take note of Geoffy's pattern... Read carefully all of Geoffy's exchanges with posters here and other forums around the internet. Whenever posters ask about or take issue with Geoffy, he turns those questions and issues around and accuses the poster of the same. Geoffy often refers to alcohol/ medication use, sexual dysfunction, intellectual deficiencies, inconsistencies with facts and truth, etc.
Whenever he is questioned about his posts, he constantly replies with incoherent jabber, insults, cartoons, and often refers those issues (as above) noted in his posts back to others. Even using the exact same words of other posters. As illustrated above, Geoffy bats 100%.

Thanks Chris

You have put geoff in his place and rightly so.

Not only did geoff fail in his attempt to troll this thread, but he also failed to gain any credibility as in the schumann resonances thread and many of the others.

Practical application will always trump the non doer. In this case not only did geoff not do the applications, but he also showed that he knows little about what goes on with the audio signal and it's surroundings. Geoff ran out of gas because he has no listening room or audio system to do the practical application with.

As for the rest of the listeners feel free to visit TuneLand where we give a total break down of what the signal is doing and what affects it. Your welcome to jump in and share your experiences and the good news is, you won't be trolled by these internet audio trolls, who really don't have much to say about any topic.

May summed it up with her own words.

"Geoff using mockery and I use the method of challenging their replies"

These are the two methods as you can read that May & geoff use to troll this forum and other audio forums. Hopefully they will get to the point to let the threads exist without the trolling but in the meantime I'm glad to see the members calling them out through making the challenges about them and their ideas, to which they have answered "it's all a mystery" to them.

No mods ever rescue you when you are being "picked on" on any internet forums, right?

You are used to being bullied, aren't you?

You have developed a very good skill set of antagonistic behaviors as a means of survival, especially since you know you'll never have friends to help you.

Today was my last day playing with the Mu-metal shielding, before Harold gets here. More than likely we will be moving on to other fun stuff.

My opinion for now stays the same as it has been in the past, shielding is a variable tweak. Also all the parts respond to shielding not just transformers.

Another point that I feel is important to make. The products with metal chassis (mainly top covers) change in performance once the metal covers are put back on after the shielding is applied, which tells me that the covers and entire chassis becomes a part of the shielding process once the Mu-metal is applied. This effect is less with foil and mesh but still part of the field effect.

Mu-metal responds differently in all 3 of the setups. Enclosed chassis, open chassis and no chassis gave 3 uniquely different sounds. This was true with amplifiers as well as CDP's. Do I like the sound of the Mu-metal? I have to leave that to each listener, but the way I listen the answer would be, not crazy about the sound, with one excepting. I made a foil/wood mini panel and that was kinda fun to play with, but I doubt many folks are going to want to use this variable tweak as much as I did. Still, each listener has to decide on their own particular goals and taste. I'm here as you know to talk about the variables and not be judge of your own sound.

space vs shielding

The question is brought up about shielding vs moving parts around so as to let the field settle naturally. My answer is, nothing wrong with doing both if you wish. Spacing parts in my book is maybe the biggest tweak out there, next to transfer tuning. Materials like Mu-metal can certainly fit in the equation, but I wouldn't limit the choices to any particular type, size or thickness of Mu-metel. Every treatment I used with and on the Mu-metal the sound changed, which proves mu-metal is vibratory. To prove this further I made a variable shielding cage out of mu-metal, aluminum, zinc, brass and wood and was able to change the sound with the adjustments.

Space is a huge tweak, as well as transfer tuning and the meterials used. Would I call Mu-metal the savior of audio? On it's own, no. Mu-metal is like any other tweak. You can treat it like an instant cure for some flus and have a hit and miss performance, or you can look at Mu-metal as a material that can be tailored to create a certain sound, or even used in a variable way.

I think it's correct to put the trolls in their place, even if it means cutting into our regularly scheduled program, or their trolling game will never end, at the same time I don't know about anyone else but I've been listening up a storm.

I made my next post on the topic here, and felt good about the report and I don't have a problem with making more reports, and if someone wants to jump in that's fine (with hopes that they will be constructive), but I'm also going to continue to state a case against the trolling. I'm not going to have myself, friends or my forum trolled without slapping the pee out of some idiot if I feel like it. Doesn't mean I'm walking around in misery, quite the opposite. After putting up with the trolling for two years I'm glad to see people doing what it takes.

Are you sure your helping your cause by trolling others? Seems to me your just going deeper into lack of credibility land and dragging your friends peter & may with you.

But I knew when I read Ron say "EVERYBODY CHILL...." that was only going to embolden your trolling. If you can't see he was only seeking to have peer relationships with both you and may, you have no humanity. Ron has been more forgiving of you & may than anyone I have seen here since I have been posting. With maybe the exception of Allen who is always a perfect gentleman too. I can not for the life of me, understand why you would not want to build friendships, instead of create enemies. You have certainly become this industries most in-famous internet audio troll, at least I hope I never run into someones worse.

Excellent! I was wondering why May tried to explain her way out of agreeing or not agreeing with geoff, so it's good that geoff is confirming that Peter & May agree with geoff on the issue of Mu-metal, and I should say that the high end audio designers use many different kinds of EMF control. I invite listeners to look at the wide range of uses and varied approaches as I have pointed out and perfomed myself.

So geoff says he knows the only & right way to treat transformers, and the audio designers including myself say there are hundreds of approaches dependent upon the desired results.

Geoff, May and Peter vs the rest of the audio community. I would put my bet on the audio community as a collective might perhaps have come up with a few ideas that work LOL.

Ron, why post at all on this thread? I don't get it. Are you trying to be the moderator? As for mu metal we -meaning me and the two dudes from Pittsburgh - already found out that mu metal is very effective in treating the large Transformer already. We don't need someone to second guess our results, specially someone not schooled on how to actually apply mu metal and which mu metal to use. You two guys assume a lot, but there's a lot more to it. Am I the only one here with real experience? I presume so. The positive results with mu metal around transformers suggest strongly that the magnetic field produced by the transformer hurts the sound. Even though you can't see it, the magnetic field is an UNWANTED ARTIFACT. You might think you're avoiding it by relocating the transformer but that is what I think is known as wishful thinking. This further suggests that magnetic fields IN GENERAL are UNWANTED ARTIFACTS, wherever they exist. That is why I now have a product called Animal Magnetism Cable Collars for interconnects and power cords. See if you can guess how they work, you know, just to bring closure for you and Michael on this thread.

I guess the while cork thing thing got lost in the shuffle so I guess we'll have to bring some closure to the cork at some later time. Lol

We do artificial atoms right

I've been gathering amps in my not so spare time to do testing with. I might pick up a few more but I already have enough to do some transformer shielding, isolating and or tuning with. I have my Mu-metal and instrument cork standing by.

One thing to report on already is the removal of some of these transformers outer "shielding" jackets. Some products come with shielding casings around their transformers to begin with. With a little careful prying they can be removed. In all cases so far I have heard the system open up greatly when removed. Also, and this is harder to do, I have chiseled away at the center core of the toroidal transformers, so I can compare hollow and filled.

This is no new exercise for me, and I will pull from past experience as well as real time listening. In all of this I want people to understand how variable your system can be if you have the will to make it so. I won't be playing the better or worst card as much as possible but more the actual change. What you get with your systems and your own personal taste is completely owned by you. I don't have any interest in swaying ones personal listening preferences, just an interest in showing some choices.
_________________________
Before applying any additional shielding I want to explain a simple few tweaks that almost all of you can do. Look at your units and you will find with most, there are cable ties holding the wires in place. Snip these wires and separate the cables. Play for about 3 to 4 hours straight and you will hear the stage start to loosen up and your front to back image should grow some. Heavier products you won't hear as much change, lighter weight (lower mass) ones and the change will be bigger.

Next raise your transformers up from the floor of the chassis. Transformers should never be on the same plane with your other amp parts. In reality all of your grouped parts should be operating on different planes. If I'm not removing my transformers away from my components I will raise them with my LTR Tuning Blocks. You can try other types of risers if you wish but for me I like the tonality of the Low Tone Redwood.

Another tweak for you way before the mu-metal is used. Purchase a good (adjustable) anti-static hair blower or even dryer. Also purchase a good anti-static equipment bush (get a few while your at it). Don't try to convert a paint brush lol. I like using a long fiber round type. You'll need to develope your own method based on where you live and the humidity, but after a few go rounds you will eventually learn how to energize your brush and then use it to remove the static around your parts. I may do a chemical static remove in places of heavy carpet and let the area reset, but after this I find that dryer treatments work fairly well. If you have setup a hair dryer you can build a shelf to set the brush on before using. Mine is a kinda like a wooden grill so the baking can go around the brush.

When I have my brush ready I'll then turn off my components and do my brushing. It's more of a light dusting, just enough to de-fuse the static charge. I get better results with the equipment fairly warm (just turned off). You can do this cold but the charge comes back faster.

So I pickup my transformer, static treat then set my transformer down on the tuning block or blocks.

Why do I do this first before Mu-metal?

Many times I find that the distortion from transformers is because of two things. One they're too close to other parts and materials, and two the charge that builds up around them doesn't have a good way to dis-charge (dissipate). I understand mu-metal shielding for industrial parts, but when we're talking about the audio signal we shouldn't always think kill. When we go to dampen we also, most of the time, are taking away part of the signal along with the energy we're wishing to isolate. The more you reference this the easier it is to hear what comes up missing.

Here's again the way I look at playing audio. Audio is a signal made up of a language and physics. If we can harmonize the energies, allowing for proper dissipation, we are way ahead of the game over trying to kill or choke out part of the signal. Any time we apply any type of filtering there's always a chance that we are sacrificing one part of the audio code for another.

If you have no choice than I recommend going slowly studying the signal as you shield. If you do have a choice there are other methods to use that may allow you to keep more of the recordings you love.
________________________
I've been having fun playing with both the Mu-metal & the Cork, and the other field tweaks I've been doing. It's good to revisit tweaks, even sometimes if they are tweaks we have moved away from somewhat.

I'm doing most of the testing in Room #2 where it's been easier to get to some of the parts, such as the wall outlets as well as transformers and other parts. So far the listening has resulted in "trade-offs" and not so much "improvements". As we have been saying, it's important when testing that one takes their time and doesn't get too caught up in the "flash" moment of change. This is also a case where I am able to test placement of the parts and other materials around the electronics, which is giving more to the signal than just trade-offs.

This tweak depends as much on the mindset of the person doing as it does the actual doing. Here's what I mean. If you take a stock unit all crammed together and built like a battleship and do the Mu-metal I can see why one would like it (maybe). However start to remove the restrains on that same unit and apply the Mu-metal the same way and the results are mixed. There's clearly a difference between the two mindsets, opening up and closing in. When I applied the Mu-metal to the stock unit I could hear into the music more, but it came with a signature that sounded more Hi Fi than raw notes. Good on one hand and a little disturbing on the other. Involved as the music was, I felt like I was in a Hi Fi box, and moving away from the room it felt like the music didn't carry with me. I'll get into this more later.

The cork is more interesting to me (well maybe), because this is the type of tuning I do every day and I was able to compare the cork to many other materials, such as balsa wood, corrugated cardboard, honeycomb wood, natural sea sponge and others. All of these have their own presention and comes down to how far someone wants to go in the area of transfer tuning.

Also a good time for a note. Just because something is called instrument cork, doesn't mean they all sound the same. This thread should be one that opens us up to many different thoughts and not limited to isolation or not, cause this would be a mistake and at best nearsighted. Both with the Mu-metal and the cork there are tons of adjustments to be made and this means neither of these two are isolating, but more interchanging or intermingling with the associated energy surrounding the area.

Another note which I refered to above, is the actual design of each component as far as layout. We need to spend more time looking at not only the parts used but also the layout of the parts and explore the math of electronic part spacing and function. There's a ton to be learned here when these components are taken out of their housings and spread out. And this is where the field and vibratory signatures should be studied by the industry and is not. To take the next step in design or understand why low mass or proper spacing is so important we should take a step back and look at the whole components in a box concept and pick it apart some.
___________________________
I'm on my last stages of the Mu-metal and cork adventure.

Just as a reference, I didn't have the time to dive into the big boys like I was going to (to many coals in the fire), but I had a fairly wide range of units to work with. I ended up working on two Technics (old and new school), Pioneer, Sony, Sherwood, Jolida and Audio Source. I went this route also because I didn't want to move around 50 pounders.

I started all my listening stock and took things to the next level by removing the cable ties and the tops off the units. I untwisted the wires and installed new hard wired power cords Bare Essence Type1 and Essence Ends. All the screws on every unit were tweaked to the tad loose, some screws removed completely. Even with just these minor tune-ups every amp became a different, more expressive animal.
___________________________
Thanks for the update and desire to keep this on topic, and productive Ron. As for myself, points will stay in the empirical listening domain as usual, but when Harold arrives early next month I'll see if he wants to move forward or move on to more important issues. We travel along at a pretty good clip and sometimes have to decide if it's worth our time to redo testing.

My findings were the same as what Ron is speaking of. You don't need to do much to experience the changing. The differences from the listening side might as well have been a gauss meter cause one could hear the change even as the transformers were being moved. I'm very use to listening sessions as it is what I do almost all day, so maybe I'm more sensitive when a change is happening, but with these particular sessions on several amplifiers I once again am not all that crazy about the shielding of the transformers and I might add the influence on other parts. This is certainly not a "one size fits all" tweak, and I think Ron would be in agreement here, if a person is not going to take the time to explore variables, than merely adding Mu-metal, they may not really be able to get their mind and ears around what is happening here.
__________________________
Today was my last day playing with the Mu-metal shielding, before Harold gets here. More than likely we will be moving on to other fun stuff.

space vs shielding

The question is brought up about shielding vs moving parts around so as to let the field settle naturally. My answer is, nothing wrong with doing both if you wish. Spacing parts in my book is maybe the biggest tweak out there, next to transfer tuning. Materials like Mu-metal can certainly fit in the equation, but I wouldn't limit the choices to any particular type, size or thickness of Mu-metel. Every treatment I used with and on the Mu-metal the sound changed, which proves mu-metal is vibratory. To prove this further I made a variable shielding cage out of mu-metal, aluminum, zinc, brass and wood and was able to change the sound with the adjustments.

Space is a huge tweak, as well as transfer tuning and the meterials used. Would I call Mu-metal the savior of audio? On it's own, no. Mu-metal is like any other tweak. You can treat it like an instant cure for some flus and have a hit and miss performance, or you can look at Mu-metal as a material that can be tailored to create a certain sound, or even used in a variable way.
