Bybee Quantum Purifier Measurements and Double Blind Test

[aardvarkash10]

Can you be more clear, Brian?

its the signature line shown in the top of the first screen shot you posted John.

Quite apropos.

Do you mean: pico scope 6?

John,

You got to admit its a good one..LOL

How many components are sold in electronics catalogues without data sheets? or access to online data from the manufacturers.
Off course in these Halcyon days of RoHS I seem to remember something about material declarations...

The new Bybee Slipstream Golden Goddess products are the culmination of decades of research and development by Jack Bybee.

Interesting, usually doing decades of research, you would accumulate some metrics of your designs and progress, I have studied PCB design for decades and have a wealth of information, lots of it dated (1979 is Ti guide on SMD design!) most of which I am loathed to get rid of, so someone working at a level JB alludes to, he must have a wealth on data and information...
Oh just remembered, its all hush hush, cant have any foreign powers getting the secret, only true blue audiophiles.

Wow what heat.

As far as I am concerned SY, myself and very few others have ever tried to measure the results of a Bybee device.

Now SY and I get different results, we also measured different versions. I can tell the difference between my Bybee and my first test resistor. I have four more that came in and comparing those to the Bybee may show other differences.

Now I just finished up a small sound system and need to clean my desk before playtime.

Now if anyone else wants to pony up and buy one they can try their own measurements.

Opinions are free and worth every bit of their price.

Here's John's chart put horizontally for easier reading.

Here's the pic with a little sharpening from XnView.

With the resistor removed, the input drops from -47dB at 22 MHz, (I presume MHz), down to -66.5 dB at 0.5 MHz. Then it stays steady all the way down. Not sure, it could be KHz instead of MHz.

What are you seeing?

RF choke?

[simon7000]

Attached. Results show the loss across the device under test. Higher levels mean more reduction.

 

[simon7000]

These are the rest of the measurements. Can you sort out the differences?

 

[M Gregg]

Looks like a choke,

What effect does the input impedance have?

Regards
M. Gregg

 

[simon7000]

Then why is the sine wave not affected? Both devices measure close to the same inductance.

 

[M Gregg]

OK you have me

What do you think is happening?

Frequency selective choke...Nahh

M. Gregg

 

[simon7000]

No clue, no guesses. Will wait a bit and rerun the experiment with more comparisons and different levels.

The Bybee seems to react to complex waveforms not simple ones like DC or sine waves. That is not easy to explain when one is limited to circuit theory.

 

[M Gregg]

It can be made,
So it follows some principle.

What effect does the output loading make?

Why is the info having to come from here?

Regards
M. Gregg

 

[john curl]

Horizontal scale is KHz/div, not MHz/div.

 

[SY]

Here's the pic with a little sharpening from XnView.

The shape of this is suggestive, despite there being no clue whatever as to test setup and what's being measured...

Crap, this is the amplifier designer person here defending this. )-: On the good side, I can eliminate some amplifiers from my acceptable list and honest list (-:

 

[peteleoni]

Just how much oil is there in a snake, anyway? I've always been curious about that.

More and more and more and more every second until it explodes. soon.

 

[peteleoni]

So what I want to know is this: Can you put a price on honesty? WTF?????? I find the older I get the less I can tolerate bs, especially my own. This device is dishonest.
