The LT1028, LT1128 and LT1155 datasheets almost fit that description. You can derive the 3.4 pA/√Hz equivalent input noise current from the total noise versus unmatched source impedance graph somewhere near the end of the datasheet, while the 1 pA/√Hz that only applies under unrealistic conditions is much easier to find.
I don't know much about claims and devices other than Bybees, purple felt pens on CD edges, and Schumann Resonance frequency. For those three, there is probably some scientifically plausible audible/perceptual effect.
Regarding Bybees and according to JC: Bybees work by producing a small bias voltage when current is passed through the resistor. The resistor is inside and electrically connected to a coating cooked onto a surrounding ceramic tube. The coating on the tube needs a small voltage to bias it on, which is not so unusual in itself. For one type of example, most of what is interesting about tunnel diodes is occurs at less than .7v of bias.
Question is then what happens when the coating is sufficiently biased? My best guess based on some observations by JC about when there was an audible effect is production of signal-correlated noise.

I was writing about this thing:

which is a Bybee QSE, because @DCE1198 has the impression that that is what the thread starter was looking for. I don't see what other products of the same company have to do with that.

Slipstream Purifers are fitted with electrical leads for connection. Bybee makes more than just one product.
Ah, no idea on that one.
Do know Jack Bybee passed away, and JC thought Bybee's nephew was taking over the company. JC expressed some concern that the nephew might not be as attentive to manufacturing process details as Jack was.
What is the correct direction in AC current? In AC current flows back and forth 50/60 times a second.
You have to flip the fuse 50/60 times a second in that socket. No wonder no one in their right mind hears the difference.
Fuses have been known to exhibit thermal distortion. Some of it may depend on how the fusible element is connected to the end caps. Audible directionality of AC fuses, however, is hard to imagine. That said, the image referenced in the above post shows the fuse installed in a direction where one end may be more subject to heating from adjacent electrical connector contact resistance. Possibly that could be a reliability factor depending on fuse internal construction.

Black body could be in the name of the product. Nobody who remembers this? It was a box with a circle on the side.
I have found it. I was squared at least.

You have to search diligently to find the Blackbody manufacturer's get-out clause: "This is a new method of addressing EMI & RFI so depending on your system's susceptibility and its actual resolution; the improvements will vary from system to system".
I see it now - a link within your link showing the BLACKBODY v.2 (which is cylindrical).

Around 2005 I gifted John Curl a small bottle of my tiny crystals. John gave it to Bybee. Many years later crystals popped up in bybee ‘s work. Coincidence?
