Danny at GR getting bad Talk Back from many of his viewers

I realize it's a poor, nay, inaccurate analogy but the "life sciences" don't work like that.
It's probably a good thing, too, since the harder we look, the weirder things we find.

Cf., e.g., Nobel laureate Carolyn Bertozzi (first one in my line o'work) who stumbled upon (in the best Pasteur-esque sense of the notion!) glycosylated RNA a few years back.
Whoda thunk it?

Small RNAs are modified with N-glycans and displayed on the surface of living cells - PubMed

Glycans modify lipids and proteins to mediate inter- and intramolecular interactions across all domains of life. RNA is not thought to be a major target of glycosylation. Here, we challenge this view with evidence that mammals use RNA as a third scaffold for glycosylation. Using a battery of...

Or retroviruses, not to mention prions, which sort of blew Crick's charmingly straightforward "central dogma" out of the water. Well... forced agonizing reappraisal of it, at any rate.

I stand sit corrected!

I guess I missed this. I wonder how Dave is doing. I'll ping him...

Perhaps encourage him to join ASR and explain the science and engineering of his device. It is quite extraordinary if it does work, and would be of great interest if he has an explanation or technical details to share. Call me doubtful that it does anything at all. Lacking evidence, my doubt is eternal.

Incoming AC noise is absorbed and de-correlated across all three legs — Hot, Neutral, and Ground — reducing high-frequency contamination before it reaches your components.

What does that even mean? It sounds like an oxymoron to my lay reading.

Here is the full product description. Anything legit here at all?



UberBUSS Power Filtration System

The UberBUSS is a no-nonsense, high-performance power filtration unit designed to deliver a clean, neutral AC foundation for serious audio systems. Unlike many power products on the market, the UberBUSS uses filtration only — with no MOVs, surge suppressors, or devices that add noise, color the sound, or restrict current.

Engineered for True Neutrality

At the heart of the UberBUSS is a three-stage filtration system:

Reactive Core Filter

Incoming AC noise is absorbed and de-correlated across all three legs — Hot, Neutral, and Ground — reducing high-frequency contamination before it reaches your components.

Power Factor Correction Network

A dedicated PFC section increases usable power under the curve, improving micro-dynamics, macro-dynamics, transient attack, and overall system responsiveness without limiting current.

After Filter Receptacle Stages

Each receptacle includes targeted filtering to keep noise generated by connected components from back-feeding into the main core, maintaining a stable, low-noise environment across the entire unit.

High Current Delivery — No Choke Points

The UberBUSS is current-limited only by the IEC inlet.
The main filtration core itself can support 40A continuously, and the design uses:

No inductors anywhere in the signal path
< 0.003 mH end-to-end inductance
< 0.0035 Ω end-to-end resistance
This ensures your amplifiers and source components receive unrestricted current with no compression of dynamics.

Sonic Results

With noise floor performance better than –125 dB, the UberBUSS provides:

A black, silent background
Increased clarity and low-level detail
Improved dynamic expression
A naturally smooth, neutral presentation
The design philosophy is simple and consistent: first, do no harm.

Standard configuration includes:

Furutech FI-06 NCF 15A IEC inlet
Four cryogenically treated Pass & Seymour 5362A receptacles (eight high-current outlets total)
Pricing & Warranty

$1,595 for the standard configuration
Lifetime Warranty
30-Day 100% Money-Back Guarantee

The design philosophy is simple and consistent: first, do no harm.

The simplicity and consistency involved are vastly understated in that assertion -- the second aspect of that "design philosophy" went unmentioned, that being, "...second, do no good."

Just an FYI-
Dave said he used a Fluke Norma 6000 in the development of the Uber-BUSS, and the GR version is the 7th gen. Mine is apparently a Gen1, and considerably different than the current model.
Dave also said he only had 3 returns over the entire run duration of all the different models.

Just more information for anyone that might read it. You are welcome to think what you want.

I also plugged my 65” Vizio 4K TV into the UberBUSS. The blacks got blacker and the brights got brighter, which improved picture resolution in every way. I had to recalibrate the TV to optimize it for the UberBUSS. A very nice, and unexpected benefit, indeed.

To test whether I was imagining these improvements with the P.I. audio group UberBUSS was easy enough; I just took it out of my system and plugged everything back into the wall outlets. To his credit, Elledge urged me to do this. And when I did do that, I missed it immediately. The sound lost a good bit of soundstage and low-level detail, and it became, well, slower. Notes did not seem to be flowing in time with other notes as accurately as they should.

Dave said he used a Fluke Norma 6000 in the development of the Uber-BUSS,

I looked that up. It is a portable field power analysis used for motor controllers and such in industrial settings. It is not a lab R&D instrument. It does show harmonics and such but with much lower resolution than what I measure. That aside, I am not seeing any data captured by this tool. And at any rate, if this device can be measured with the Fluke, the notion that its performance is not measurable is nonsense.

The reviewer also seems to overlook simple stuff like ratings. The specs claim the core can handle 40A limited by the connectors. The AC input connector is claimed to be a 15A Furutech. Here is the pic from the review…

In the upper left, the rating is clearly shown to be a 10A connector. Seems the reviewer was too excited by uber aura to simply check the specs. While there are a lot of claims of miraculous performance, what about basic safety of this device?

UberBUSS may actually be a decent line noise filter, but there is no sign of even simple protections like a fuse or circuit breaker. What happens when the load(s) demands more current than the parts are rated to handle? The case is MDF to allegedly avoid eddy currents but is also more flammable if the parts get too hot.

Lacking UL/CSA/CE certifications, there does not appear to be any due diligence regarding the safety of this device. In this case, basic electrical capacity measurements really do matter. Does not appear GR did any measurements but is offering a “lifetime” warranty. Wonder what that warranty claims to cover? Liability?

Maybe it's doped in snake oil to prevent eddy currents... who knows...

@Amir, I never said it's performance was not measurable. I also don't recall reading it stated anywhere to that effect. The resolution of the Fluke device isn't why he used it. It allowed him to truthfully see the power, HD, EMI, and RFI.

@RickS, that is a 10A at 250VAC IEC socket, and likely 15A at 125VAC. Since it runs standard household 110V, I don't feel this is misleading at all. More often than not, Dave preferred the more solid connection of the 20A IEC, but cord availability was less accessible to most users.

As to the UL, fuses, etc; isn't this another case where your electronic components should have that taken into account already and not needed here? It does isolate the AC wiring as required to protect the end user, but i feel a fuse would be a welcome addition. I have a heavy Tripplite suppression unit between it and the wall, and outlet strips with breakers plugged into it. Not that anyone else uses it how I do.
