Extreme Snake Oil

[Thighsofsteel]

The general view of the audiophile nutters over on PFM is that the noise will effect the DAC. At least that is what I think they believe. Nigel from Reiki has been asked on many occasions to show his devices reduce noise in anyway, but he wriggles and squirms gets his acolytes to attack you, asking all kinds of inane questions to deflect. Not once has he show a single piece of data.
As Keith says, He wont. he is a high lord of snake oil

Still stunned there's still a market for this stuff, especially in the cash-strapped UK...

It is also a brain cell strapped market. They will believe anything

Ethernet is shielded and the sockets go to case ground. At least that's the case with PCs and I assume the generic sockets in the back of a streamer too.

Interfering with analogue performance by em intrusion is also the argument for audiophile fuses, power bricks, conditioners and so on. While it is true there is a electric connection it is hard to prove or disprove there is an influence. The burden lies with the $$$$ fix salesmen and I have never seen anything beyond talk and marketing.

Ethernet cable rated as CAT 6A (required for full 10G Ethernet speeds at maximum length) and higher is shielded. Cable rated CAT 6 (good for 10G at limited distances) and below relies on twisted-pairs and isn't shielded.

The shielding on ethernet cables can cause issues by creating ground loops for analog signals, since it is connected at both ends of the cable and to the case of connected equipment. Within the past week there was a post on AVSForum from someone who has created a ground loop (hum) in an analog signal from installing CAT 6A cable. Since CAT 6 cable is good enough for most installations this ground issue likely won't become a major one in the near term, but it is something to be aware of if you are 'future proofing' your ethernet network with CAT 6A cable.

You are right, the regular cat6 patch cable brings no shield connect.

With cat6a and installation cables, field service plugs etc. it begins.

That is not correct.
Cat 6—or Cat 6A—designates only the category, not the shielding type.
Cat 6 and Cat 6A are available in unshielded versions as well as in almost all shielding types—for example, as UTP, F/UTP, SF/UTP, FTP, F/FTP, S/FTP, etc.

I think I never used a cat6 cable that's not sftp. But I believe that even unshielded utp is available, as are all the other flavors.

While the patch panels and backbones are usually grounded, the device on a simple patch cable mustn't join in. For audio applications the field serviceable connects (foil and shield to case) could be trouble.

The Don Quixote's of audiophile Shambhala. Always chasing a dream and their Svengali experts creating the oasis paradise in the desert that you seem to never reach. While the scientific priest class mock the ignorant dreamers with pride and pontification. The dogmatic objectivist looking down at those with faith in the subjectivist miracles. Maybe the miracles are just yet to be realized technology founded in physics principles. Or maybe, man's arrogance will always dominate before we discover the truth. Maybe life is just messy and most of us don't know what we don't know.

…Before you can claim a recording sounds live it has to have been mixed and mastered with that objective. It almost never is. But many want to take a recording that was mixed and mastered for, say, clarity, and turn it into a live performance in a hall with a 5-second RTA-60 like their favorite cathedral. The philosophy of playback for most here is not to make a common recording something it wasn’t even intended to be, but rather to present it as exactly how it was intended as possible.

…

Pursuant to the thesis of this post and the others in that little subthread, I measured the sound pressure level of the finale to the Brahms 2, as performed last Friday evening by the Fort Worth Symphony Orchestra. We were seated on Row Z, 26 rows back from the stage, about 10 feet from the back wall and under the first mezzanine. We had to be 100 feet from the edge of the stage, with another 50 feet to the back of the orchestra.

The quiet bits measured right around 60 dBC, and the peaks were at 96 dBC. That’s 36 dB range from the softest tones to the loudest. Reverberation tails were much quieter, of course.

(That’s a lot of room gain, by the way, only about a 10 dB drop from the instruments themselves, at least for this work.)

And the Brahms 2, wonderful though it is, isn’t as loud as many. It ain’t no Shostakovich or Holst.

Has such dynamic range ever been distributed on a recording? I’ll bet not recently, but now I am compelled to play my recordings of the Brahms 2 and measure the sound from my listening position.

This is Marantz "sound master" talking about "tuning sound" on amplifiers. Damn, never knew Marantz is some serious snake oil BS.

 

[Ruediger]

Whenever I see videos from that soundmaster room, I think it's one guy's department with a budget. Got the speakers he likes, expensive looking cables and even some of those wooden ladders.

Of course there is more to it. But marketing is also important I guess. They would also have guests from the complete fool department (but help sales) that expect a certain show level.

I’m stunned by the idea of these tweaks ”removing noise” where none of it is visible in the output of the product. So there is unmeasurable noise that humans can hear

Only in the brain cell deficient audiophile world.

 

[pinger]

I like Marantz. I have the CD player and Int amp ( both 6007 models) . I bought them for looks, size, ergonomics, build quality and price. Nothing to do with sound quality since all properly operating CD players and amps sound the same. Sounds like the dude actually believes what he's spewing though LOL

Home audio is pretty much a solved problem, and there's not much new under the sun that would make any noticeable improvements in the S.Q. of a competent system. So, gotta come up with something that supposedly will improve S.Q. to keep the cash flow going. Roll out the kay-bulls (cables) and Tice Clocks to git 'er done.
