Ferrite beads are actually not recommended in the USB 2.0 and above cable specs, since it can cause data errors at high speeds. For ordinary USB audio it probably doesn't matter, though. KozmoNaut fucked around with this message at 00:11 on Feb 1, 2016 |

My DAC seems to need a cable with one because without it it restarts when I turn off my desk fan.

I pulled it from a printer just so I had something to use with the iphone and cck in case the store didn't have any loose cables and/or weren't willing to pull one out. Worked fine for the brief auditioning I did.

Yes, they effectively raise the inductance in the cable, attenuating high frequencies* beyond a certain point. *In the MHz range. E: Here's another fun video from AV Show Reports. How would you show off your brand-new speakers that have been hyped as some of the best in the world for every kind of music? By playing some all-midrange cello music, of course!  https://www.youtube.com/watch?v=f6x1yY5C1DM KozmoNaut fucked around with this message at 15:26 on Feb 1, 2016 |

Cello has a lot of fine detail and over/undertones that are VERY hard to capture and reproduce in a manner at all similar to live.  e: yep, those speakers sound like unremarkable boxes crammed into the corners of a nearly cubic hotel room Panty Saluter fucked around with this message at 18:11 on Feb 1, 2016 |

I think it's mostly down the recording side. Compare the live cello in that video to the recording - even in a totally suboptimal situation the body resonance and other fun details are plainly audible. Most cello (and string) recordings I hear sound like they're recorded way the hell back in a non-resonant space, and then compressed and eq'd until everything is nice and smooth. I'm sure most people prefer it but it's boring as hell to me.KozmoNaut posted:If my car stereo can do a reasonably good job of it, it can't be THAT hard.

It probably does add some distortion and nonlinearity to the sound, in a way that some people find pleasing. Pretty drat expensive for a non-configurable EQ, though.

You can, and you don't even need to lie about it. Products like these and Beats by Dre are a response to the last 50 years of efforts to make audio reproduction as perfect as possible. There is definitely a trend and a market for products that make music sound nice and warm and fuzzy. It's kinda why things like the vintage radio posted a few pages back still have a purpose, their cabinets are almost made the same way the body of a guitar or violin is made. They have a unique sound that some people find very pleasing. Edit: I just wish these companies would get rid of the awful blue leds and use nixie tubes instead.

So, yeah, really liking tube gear is right up his alley. He's into it. I don't think he's uncomfortable with newer technology, he uses a pretty swanky streaming box as his primary music source, and does a lot of reviews of newish tech stuff. I kinda like that he reviews stuff from his "normal bloke with limited tech knowledge" pespective and is quite honest about the limits of what he knows. He does have an appreciation for older tech and obsolete formats, from the well-known stuff like Laserdisc and 8-track to wonderfully obscure stuff like the Tefifon and the Playtape. And he has a completely reasonable nostalgic love for cassette tapes since they were his primary source of music when he was younger, but maybe that's just because I also grew up with cassette tapes as my primary music source and only practical portable format. The discman took some years before the anti-skip was actually usable, but a walkman would play just fine, even if you were jogging or something. https://www.youtube.com/watch?v=jVoSQP2yUYA I have to say from this video and my (limited) experience with type IV tapes and Dolby S that you could actually get some remarkably decent sound quality out of the darn things. Pretty good for a format originally only intended for dictaphones and reasonable quality voice playback.

A quick googling suggests that combo would get you 18+khz with 80+db of SNR, so virtually indistinguishable from CD unless you have perfect teenage ears and/or crank it enough to hear the hiss.

So it's a perfect avatar for this thread  It's the weird space of essentially being one of "those people", just being on the opposite side of the coin. While the tube processor no doubt adds some euphonic distortion (I'm guessing the small amount of background noise is what makes it feel more spacious - maybe some phase distortion and crosstalk too), it's the sort of novelty that wears thin with repeated listening. I would know, I actually bought one of the first "3D Stereo" processors SRS Labs ever put out. ...and yes, it's a very expensive DSP/EQ with only one mode to play with. The video still amused me.

I liked his cassette video, which I stumbled on despite not watching anything like that on YT normally, so I'm willing to give him the benefit of the doubt on his other videos. He might not always be right, but he's not an audiophilic nut job given that he was happy to say Dolby S sounds really good, and it needed him switching back and forth the lossless source to notice there's a difference. It was also a pretty well produced video, so an enjoyable watch.

The end that goes into the computer is the one that's confusing. I can see how a reversible micro-usb connector would work, but the other end... I believe it does (the reviews say it does, sometimes poorly) I'm just curious about the mechanism and none of the reviews actually delved into how the end that goes into the computer/usb port actually accomplishes the ability to go in backwards. Is the plastic bit holding the connectors flexible and floating in there?

It is; I wish I could say it's totally perfect but it's kind of takes a surprising amount of force to put in at first, but it's honestly not something that is too bad once you're used to it, and it seems to have mellowed out a bit. It mostly feels like a really stiff USB plug. It's great just taking something and plugging it the gently caress in, and it just WORKS, regardless of whether you look at the port or not; this does lead to the unexpected issue of trying to jam it mistakenly in HDMI ports on the side of my laptop, though.

I had a similar problem with DisplayPort when it first started becoming common. I got some crappy chinese counterfeit cable where they had just wired 1-1, 2-2, 3-3 and so without even bothering to look at the spec, which clearly says a couple of pins are supposed to be unconnected in a DP-DP cable.

I already have enough trouble convincing people that using £1 chargers is a really bad idea. I've never personally dealt with any dangerous lightning cables, even pound store ones, but might just be lucky. Maybe lightning is designed in a way where it's got more safety features in case of shoddy construction.

Funnily enough I've never had the incompatibility error people have had, but the lifespan of £1 cables is... limited, we shall say that. Dead useful for emergency backups though. I did what the iPhone thread title said and bought a double pack of Ankers, they seem pretty decent.

Oh boy oh boy. Someone remarked that when you see the name Accuphase on the front of an amplifier, you know the sound quality will be much better than if you had bought a Denon or a NAD or some other "mid-fi" component. I asked him whether the name was more important than the specs, and jokingly if that was because the signal goes through the nameplate on the front and if that somehow makes it better. I should not have done that. quote:1: I have never written the name means more than the specifications, but a TROLL probably reads it enough such.  RE: his point #5, about 8 months ago I did back out of a DAC listening test because it was 50 miles away and I couldn't find the time for it. It was also going to be set up by a raging crazy-rear end audiophile, and I honestly don't feel any compulsion to visit a person like that. That was on a completely different forum that I subsequently stopped visiting, because most of the users were rabid cable fetishists, all circlejerking over the latest overpriced junk and not at all interested in constructive debate. I have no idea why he considers it necessary to hold a grudge on that basis. I'm kinda hoping I can get his blood pressure high enough to burst a vein or something, preferably all over his expensive high-end fancypants stereo.

You're doing good. It's always entertaining with people who jump to the conclusion that anyone who doesn't agree with them must be trolling. A friend of mine is doing a similar thing in various homeopathy / natural remedy / alternative medicine groups on Facebook, trying his best to teach people some critical thought. The reaction is pretty much the same that you get, "if you're not with us you're an evil troll and a plant by BIG PHARMA".

They are so fervent in their beliefs that they absolutely refuse to entertain any suggestion that they might be wrong. If any perceived differences disappear under double blind testing, obviously the test is flawed or the "stressful" testing conditions interfere with their hearing, which is perfect in every way And if attacking double blind tests in general doesn't get them anywhere, they'll start attacking the hearing and gear of anyone who disagrees with them. The gist of it seems to be that there is a minimum amount of money you absolutely must spend on your stereo, to have any hope at all of getting good sound quality. Curiously enough, this magical minimum required "investment" is always slightly less than what the audiophile in question has spent on his own gear  It happens every drat time my gear happens to be brought up. "Studio monitors don't sound good, they're too analytical", "Your DAC is cheap and only meant to connect TVs with TOSLINK outputs to stereos, it smears the details", "The analog->digital->analog conversion in your DSP crossover introduces noise and inaccurary to the signal" and so on. I'm just wondering, is my sound too detailed, or not detailed enough? Or do the two factors cancel each other out somehow in magical audiophile woo-woo land? I'm stumped.
