Teo Game-Changer IC's - get on the bus!


I wrote an extremely long review of 4 cables auditioned in my system recently. I pontificated for way too long and it was more an outlet for me to tell a story that cables do matter and how much each design can make your system sound. The last cable through was the Teo GC IC purchased here and it truly was a game-changer in how it shifts our paradigm about what wire gives us as "truth" and what this slurry of Ga-In-Sn can do better (IMO). Not a technical review but an emotional roller coaster through 4 different topologies:

Ribbons
Graphene
Multi-strand
Liquid

I'm happy to re-broadcast that here but it is very long (6+ MSWord pages long). I'll point to it for now and take your advice.

Bottom line is the GC cable is truly stunning in what it can do and for us mere mortals who cannot spend thousands on cabling, I believe it can elevate anyone's system to new heights.

Hello, Apologies for not answering sooner on both questions.

The GC cable is unique in the line up. It is RCA single ended only.

A balanced cable would be a wholly different configuration and design, and would be priced accordingly. A digital cable (which we make in RCA terminated format) would also be a different design compared to either a balanced cable or the GC RCA cable.

The GC sits alone in our range as a very cut price direct sale unit, serving as an introduction to the technology.

Hello, yes, that is correct, we make a digital cable in our regular line up. To work it's best, required -in my thinking- some custom shielding/ground materials I had to develop.

I made a interesting little short video that illustrates the evidence of the critical difference of liquid metal vs solid wire.

Now I have to figure out how to post it...(I'll probably start up a YouTube account.)
Imagine what all that does to Atmos and surround systems. If one wants to be truly put into the film, well, 'natural believability' in soundscapes, is ultra critical.
Works for us (re someone else buying them)....Teo will honour the warranty transfer, in this case.

Warranty valid only in North America.

Hello,

The cables will not work with phono level signals, MC or MM. They are  unshielded.

One tends to experience considerable hum. (speaking politely).

The liquid metal is unlike solid metals, and this brings about some seemingly counter intuitive results, in some cases.


The cable of the subject of this thread, the GC, in it’s design, is very robust. But like anything, it will break if mishandled. When I say mishandled, I mean mistreated. The very first cables made, almost 10 years ago, are still functional, and working. In use.
That would be from the 'standard' line of cables. The only XLR we make, at this time.

There is no GC  XLR cable. If it was in existence, it would be a GC cable in name only, as each design is unique for it's quality range and application. I'm reluctant to give a price for a GC XLR, since it does not exist.

As for the 'standard' XLR, it is considered competitive with anything, no caveats, no restrictions.
Apologies for the delays, we are moving along on the orders as fast as we can.

The materials for the Splash have arrived and now we are making them, and then a burn in test-listen, to be sure things are as they should be.

The Splash Rs is terminated with WBT's finest RCA connectors, the 0152/Ag.
Hello Mark, yes we received it and you went on to the list the very same day.
Glad these are working out for you guys. I need to buy the Splashes but am building a deck right now and it is sucking my cash supply down big time.

I moved on from the Cerious IC’s pretty quickly. The Cerious SC’s are fantastic for the price.


I was wondering why I did not hear from you. (after I sent you the Splash Rs pricing)

I guess you are in deep the misery of spacers, trying to get the end cut right, cement corner post leveling, crying to the heavens about bad crooked but ridiculously expensive boards, worn out shaky triceps, sore necks, and bad fitting knee pads.

can't exactly answer for Teo, but I ordered the Splash on April 7th and the GC on April 10th and none of my orders have shipped yet.  But I think it may be shorter now depending on if they have all of the supplies and parts they need. 

Yours is the oldest unserved order in the system. And the parts to finish it are finally landing today. Which is a good thing...

We're setting up new adverts to say '9 business days' before the ship date as we are trying to slow the orders down a bit. Just so we can catch up. Which we are getting to (speeding up, that is).

We are also moving to a new facility, which complicates matters. Apologies for the minor slips in delivery/ship dates.
As for any 30 day trial periods, that does not begin until you sign for the parcel, at delivery. Even then it is not a strict number. Generally, you’ll know within minutes of when you install the cables and hear a few notes. We are running at an approximate 3% return rate.
Teo_audio-
How does someone register there cables with you? I've asked several times now via emails through my audiogon purchase, your web site and through a question in this thread.
Hello,

apologies for that, we are just a few people, and sometimes things like this slip a bit, with so much being on one's plate.

If you pm me we can exchange emails and the serial number of the cable, and that can stand as the record until we can make it more formal.

thanks,
Hello Ozzy,

you sent a message on the 19th (at 11:13pm, which is effectively the 20th), and received a reply on the 24th (Monday), according to my email record...(ie, two business days). Which is a bit long, apologies for that.


Hello Gak, it’s all good. Yours (or that of others from those few days-as time periods go).. will be going out the door mon--tues-wed, kinda thing.

We got hit with a big lump of sales at that time, and it’s stuck in our manufacturing craw. We’re giving it the Heimlich, and it’s working itself out.

On the other side of such semi-golden news, I am personally notorious for underestimating the time it takes to get things done. So be sure to reserve a few grains of salt for possible use.

KH
The time frames are about to drop down again. I'm about to change the adverts to say 4-5 business days until shipping, from their present approx 9 business days.

Meaning, the last back orders and orders on the docks are going out over the next 5 business days.
I have a broken hand/wrist that I over-estimated the condition of the healing, when this order thing started to take off. I was forced to slow it down, against my will. The alternative was to damage my hand/wrist even more than it already is (from my being ’attacked’ by a car in a parking lot), by ignoring the inflammation created by over-working it. I was going to mention that in my earlier post, but decided against it.

Additionally, your GC was purposely put on the back-burner, as your splash Rs was moved to get to you as soon as possible (as an earlier order). So the 32 days is unrealistically high and you are the only one who has experienced such an extreme delay, on that second cable.
Be it known, though, that the cables, cutting edge physics and sound quality as they may be.....they are just an opening act.

We have more. Much more. Technology that is, overall, at least 20 years long in development. More on that at a later date.
Don't worry about the 30 day limit thing. Those are just numbers that have to be on paperwork. The number is flexible, upon the asking, for the most part.
It is connected to the fluid being a superior material in the complex impedance area of dynamic distortions being added to signals. This is the ’action’ point of audio cables.

Since the fluid cannot ’add’ such distortions and all wire does add those distortions, especially when you crank the signal levels...this explains your ability to have air and space at the same time it never goes harsh like wire does. Or that the ’wire’ system (non fluid wire cables) is so damped and dark it obscures signal along with the seeming fix.

Which leads to the known circular argument of always changing your wire loom to try and fix a problem ~which is endemic to the wire itself~. It simply can’t be done.

Only the fluid metal gets you past this point (when wire/solids are applied to audio signal scenarios).

This seems like a ludicrous statement on the face of it, but once the wire has been compared to the liquid metal- by an observant listener-... it all becomes quite obvious.

When people try the Teo audio cables they tend to get off the cable merry-go-round.

To add, single simple permanent solutions are not generally desired in a marketing system. Merry go rounds are more desirable.
The GC and -Splash Rs’ RCA cables are now available in 2M length.

Delivery time periods have also dropped down notably.

All caught up on back orders - for the moment, that is...
Still.. tick-tick-tick..pondering a balanced version. Gonna do some tests, to see what we can do.

The fluid conductor and it's behaviour is uniquely suited to balanced signal transfer and it's design intentions.
He’s just looking to get by the forum rules and stab at something he does not understand, in any way he can.

so, without further ado:
"Liquids are the least understood state of matter ......."

"Lead author Dr Kostya Trachenko said: "This result is important for the fundamental understanding of liquids and gives us hope that we are getting close to constructing a consistent theory of this elusive third state of matter. We have good theories of waves in solids and gases but, surprisingly and despite many decades of research, not in liquids."

That no one can claim that it’s not within the realm of known physics to be different, wholly different, as it actually is that.

As no one can define it. There is no theory that is known ---to cover it.

So yeah, scientifically proven to be new and different. By everyone who counts and works in the given fields.

The scientific article from physorg (june 2017) straightforwardly talks about fluids being off the end of the functional theory train.

Now add in electricity, add in voltage and current, and more, as you have a conductive fluid. Kinetics, for example. It appears to be going a good a magnitude -and probably more- beyond known and theoretically definable sciences.
Yes, there are probably some others.

We may have to revise the ’time for break in’ upward, as they are demonstrably different than the machined earlier ETI RCA jacks we used to use.

The ETI RCA’s are machined copper, whereas the KLE ones are folded over copper. What the single folding over does, it is disturbs the crystal lattice and takes more than 100hrs to get it’s subtleties of continuity back.

We use a specific form of pre-conditioning break in/burn in... and ask that people do not use any beak in devices or hardware techniques, other than standard listening at line level. Ie, off an fm tuner to an input ...or between a line level source at 2v rms max, into a standard 10kohm and up load. NO burn in hardware/devices.
Hello Tom,

It was a possibility.... but the stumbling block, in one aspect, is that there is not a single XLR connector that is built to handle the build requirements of a fluid conductor. They are all built to anchor and strain relief via the wire body and that is a total no-show for a fluid conduit. The second problem is that the idea of error correction and how it is handled in the analog domain on an electrical signal in the balanced configuration. That is a legacy mentality and methodology and it really should not be applied to electrical digital signal transfer. This was a big problem in early digital signal on balanced lines and also with HDMI. Early HDMI cabling, termination, and i/o hardware was not up to snuff.

What this indicates is that the method itself is hobbled from the get-go and the fix for it is a greater level of exactness..an exactness that says nothing about jitter. Digital coaxial probably has less inherent jitter, besides being able to deal with fairly high data rates. The balanced design in digital signal transfer, is mostly to prevent interference when running lines all across the floor or across the given connectivity area for a concert, or whatnot. ’Pro’ does not mean high fidelity in most cases, it just means ’must not fail in operational context’, and has no designs on fidelity, just functionality of connectivity.

Ie, the best way to build an analog audio balanced cable is probably -to ignore all the pro level requirements. In a home environment those pro design standards are virtually meaningless, they don’t apply.

I (the Ken part of Teo) buy into the idea of balanced amplifiers... but I don’t buy into balanced signal transfer in home high fidelity. I happen to think that the fluid is most well suited to balanced signal transfer, probably moreso than any wire. But that does not change the point that balanced is introducing two-three-four problems into the mix instead of just one, with each problem being tied to signal degradation. The degradation comes out as subtle high frequency transient information that is false... which some will interpret as greater levels of detail.

Circling back to the start, sort of..this degradation is shown to exist via the problems that occurred when AES/EBU and HDMI came into being. those problems were tamed enough to get the bits to transfer... but again, nothing about jitter.... and in analog, this would show as transient emphasis and damage.

You listen to an all balanced system..and what do your hear....but exactly that. :) The balanced emperor wears no clothes, kinda thing. Or at least ’clothes that have an inherently greater ability to tell the wrong stories’. Some people can make or put together great sounding all balanced systems, but not be aware that doing at least as well can also occur with a single end RCA connected system. Balanced can be more like hifi and RCA can be more like music. All things being equal, which they never are... but might average out to being  -in the greater scope of the problem.

A clear headed analysis of analog audio signals, electronics, wire, dielectrics, signal transfer, etc..yields one inescapable fact..which is the best we can possibly do, is perfect signal transfer, minus some small aspects of fine detail, subtle, almost imperceptible degradation of transients and so on. Much like that of master tape vs a copy of the master, vs a copy of the copy and so on. It is more subtle than the degradation from honest tape duplication/copying, but it is most definitely there.

People try to fix that via equipment and cables and can sometimes end up with some given form of screech that finally intrudes enough that we recoil at the noise. At that given moment we may finally understand it is not increased detail, but ugly noise.
No, bumperdoo is not Teo. He has heard the Teo cables, yes. Even some of the prototypes. I believe he may have one (cable) in his system right now.

As for the passive thing, I dunno. Two reviewers both think it is ’state of the art’ regardless of passive, or active, or any given passive technology. Their conclusions, not mine.

As for science, those who have no edge and are all commonality tend to fluff and bluff the technological white paper and written fireworks. What if someone has something interesting and does not want to share the info? As sharing it causes ridicule from some and quiet contemplation from those who like to steal others thunder. Reveals in such scenarios are built out of lose --and contain no win.

If one has excellent cards -- then... keep them close and play them when best. ’Nuff said.

Looks like someone told the truth about vendor


Randy, try not being so nasty, negative, and paranoid.

That was Taras, who has not used the audiogon posting system very often, and was figuring out how it works.
Can someone share their experience between inserting the GCs in their digital/cd path as compared to their vinyl signal path? Does the GC make more of impact in one vs the other, and what is the difference qualitatively? A prior comment was that the GC smoothed out the cd harshness (my paraphrase) and I’m wondering what the effect on vinyl sound signature is. Thanks for sharing.


In our impression of what the fluid metal brings to the table it is a notable lack of the unwanted aspects of dynamic peak distortions that the complex impedance of a ’wire’ based cable imparts upon said dynamic peaks. It is inherent to most cables and wire period, to the point that many people get their idea of detail and information from some of these time smeared dynamic peak distortions. This is inherent to audio circuit design and is the entire audio endeavor in a nutshell. but it is also prevalent in cables.

The fluid metal tends to have notably less of this with respect to being an issue..and it is tied deeply to the way we hear, which is via listening to dynamic peaks in signal. Which is where these low levels of distortion occur, when the engineers test and measure. The relationship to how we hear and what is measured is not linear and engineers are looking at linear weighting in their numbers and their musing..... so they miss the point and the relationship almost entirely. the vanishingly low levels of distortion they find are actually pretty well 100% of what the ear hears. And the 100% of the signal that their measurement systems look at are not relatable to how the ear works. Completely wrong weighting. This ultra critical point is writ large across the combination of information on how the ear works vs how engineers weigh or look at the signal they are measuring. The two, at this time, are not in sync in how they are looked at and their importance/relationship to one another.

So we end up with a quieter cable (with the fluid), and the details we hear by, those complex dynamic peaks..those are less damaged, and thus notably easier to hear, it is notably easier to hear complex dynamic music structure.

The metallic alloy fluid is not ’darker’ per se, in some important ways, it is merely producing less distortions that slur and cover up fine detail, as compared to what some other technology may produce as side effects in signal conduction.

Which can mean that the fluid metal cable can be said to be capable of unraveling harmonically complex and richly detailed passages , without hiccups, or loss. Comparatively speaking, that is, as nothing is perfect. Better only, if one is lucky.

Rich microdetailed passages come through more unharmed, without peak signal etching (which is part and parcel of dynamic peak smearing). Peak signal etching is sometimes mistaken for detail, in a blunt fashion, by systems and implementations that cannot unravel ultra fine detail. Say like, bad pro audio. Cerwin vega from the 80’s, etc. And some high end audio configurations with bad design, like badly executed crossover designs in speakers. Bad crossover design is sadly, all too common. When the Teo cable is inserted in such systems, they just find it dark. Ie, trying to overcome muddy crossover and bad box design by using gear that introduces blunt force trauma in the form of hard peak detail falsification.

When people have worked hard to build systems that are not peaky and hard (false detail), but open and capable of rich detail delineation, and that delineation is built out of as little peak distortion characteristics and the person involved (system builder) can make it to be.... then they find that the liquid metal cable is doing what they want a cable to do. What they spent their entire audio design and build life, trying desperately to attain.

Ie, closer to real life richness and dynamics (micro and macro, in time and levels), and far away from muddy screechy ’detail poseur’ harshness.
Balanced GC’s are finally available, yes.

We had to create our own XLR solution for Liquid metal balanced cables to be possible. XLR’s are a particular problem for ’non-wire’ systems of conductivity. Not a single XLR available can be utilized for liquid conductor systems without major modifications of the connector. Most connectors are beyond being viable, even with extensive modification.

Liquid cables look the way they do, as it is necessary for their function. Every single micro detail of their construction is extensively worked over. Even that crooked looking label is a quality thing, not some poor build quality aspect. If we explained the why of that label, the entire industry would likely follow us.

This (balanced) was not commercially viable for us until 3d printing evolved a niche method/technology that fit our requirements. Which happened a short while ago.
