celander My Teo Audio Liquid Pre passive
I’ve never experienced a more authentic, transparent, three-dimensional musical reproduction experience, including reproduction from my previous audio systems having what I now know to possess perfectly-matched impedances throughout.
A very good passive, and from what my sources tell me, it’s a 23 position "shunt" type passive volume control, 1 fixed series resistor, and 1 variable shunt resistor (48 total), not the best way of doing a passive volume control, the "ladder" is best, "series" being the worst.

This is a 23 step stereo "ladder" using Dale resistors, total of 92 resistors total, signal still only goes through 1 series (variable) and 1 shunt resistor (variable), this give more stable output impedance compared to "shunt"

We are notoriously tight lipped due to the nature of intellectual theft which both Taras and I have endured far too many times over the years. I could name you more than one company that has come into the world (and audio world) based on intellectual theft from one or either of us. Yelled at and slapped around as charlatans on the front..while the thieves slip around the back and steal the tech and ideas away and make a living off of it. This is why incorrect information can be out there, and we won’t correct people. Too much information. The questions are all about getting responses.. so the data can be mined.
Just to make a total mess of common logic (gained from much experience by the whole industry) in the audio world, I’ll say one thing one time about our tech to illustrate how impervious it is to impedance function.
The stepped attenuator in the Teo Passive Liquid Pre, is a 23 position series unit.
One interesting thing, is that it does not change in sonic character as one raises and lowers the levels on it. Owners note this specific point as it is part and parcel of the problem of passive preamps, but in our case, is non existent.
Which is totally backward to how one understands what a series implementation will do. Which you basically said, George. Yet it still works gang-busters and and the top of the quality chain in passive or active preamps. How is that?
The preamp can, when the attenuation is set to the max pas through, pass either 1080p component video (would need a second unit to pass the third signal, component has three signal lines) OR Digital audio signals in a coaxial configuration..
It is literally, by all science and physics a totally different handling of the living dynamically changing impedance of a constantly shifting signal. that is what the fluid metal is:
it is not your father’s impedance. Period. The end. Finito. No question, no argument possible.
The physics, if you actually know it..is quite clear. Anyone arguing beyond that, really does not know their impedance at the molecular level and everything else required to understand this question and answer set about the fundamental nature of conductivity, LCR, and signal.
THAT, as an exclusive patent that locks the entire industry (all of them) out of this area of implementation (we were there first, at a ground level and grabbed the whole area)..that is why the audio cable industry recognized this.
It is also why an unnamed maker of world class audio cables..came into our display room at the 2009 Montreal audio show...and shook our hand with a big grin on his face. He warned us that the entire industry of high end audio cables felt quite threatened by us and that we need to ’watch our backs’.
The only thing that has saved them, is that we are not super ambitious and gung-ho to push huge coin into a huge push. But we have been threatened and cut down in various ways by various manufacturers in the cable world, in ways that are libelous to speak of, even if it is true.
People are slowly getting it, this problem of how basic LCR tells only a very small part of the story of why things sound the way they do.
We’ve make a big jump, here (in all technological ways) . The tech is not easily understood and this is added to the audio problem of some thinking that having good hearing and being able to hear such things - is crazy. Which is really pear shaped in the final analysis, it’s like beating up people because they are smart. Same-same.
We’ve latched on to a partial explanation of one aspect of part of a question: the the application of LCR to audio. It is the nature of humans to be dogmatic and biblical, it’s a social fabric coherence function buried in our subconscious origins of thought. And it screws up our logic function, all the time. LCR is just a echo back of the smallest part of the possible components of analysis. Yet some dunderheads crown it as king, and try to kill in it’s name... when it can’t even tie it’s own shoes.
The insanity is.. they they don’t even know what it means. The map is not the territory.
Things change in physics, by the minute, these days. Same for medical research. This is not the world of a bunch of older audiophiles, who are slowing down in their life pedaling speed. The universe is now an information field, time is not linear, spooky action at a distance is fully realized, and immorality is here, in the genetic and real sense. And much much more. WAKE UP. PAY ATTENTION.
Like Max Planck said,
"Science advances - funeral by funeral". (when the nasty nay sayers die and their grip and voice finally leaves the stage, we can get on with moving forward)
