So why doesn't their logic of having imaginary bullshit have a noticeable affect on digital data being processed ever get applied to photography? Better gear makes for better display of your digital camera photos.

But then I think that there are probably are sperg-nerds who spend thousands on various displays and such, so never mind.

It's much, much, MUCH easier to objectively judge visual media. The comparison doesn't really work.

Digital photography nerds love zooming in on pixels, and since pixels can be directly compared to pixels from different photos taken with different equipment, it's easy to directly compare gear that way. It's extremely easy to compare color, contrast, sharpness, distortion, etc. And likewise for displays. There is a whole bunch poo poo involved with calibrating your display to industry standards. I think anybody claiming to have a "golden eye" when it comes to photography equipment would get laughed out of the industry pretty quick.

Well yeah, you also have "sharpener" kernels or crazy over-saturation to make things look 'better' the same way "louder" sounds 'better' to the average joe even if it completely degrades the signal quality. Intensity vs Authenticity trade-offs are obviously subjective, but not exclusive to audio/video.

Although that makes me wonder how many of those 50k "studio quality+++ precision" rigs are just constantly tuned into a drowning smile.

I found this interesting. It's from whatsbestforum in a thread about an $8,400 power cable.

The author is the owner and lead designer of Atma-Sphere Music Systems.


I don't have the EE background to qualify what he's saying, but it echoes my personal view on power cables, etc., which is basically that they only make an audible difference when they're physically deficient. In other words, if you hear a measurable difference one of the two cables is basically broken.

What is very entertaining is how much hate he got from other people for making this post. It's apparently sacrilege to try and measure things to determine why you can hear a difference.

What he's saying is right enough to almost be credible: typical linear power supplies DO draw their current in peaks, and this can be a problem in large installations of fluorescent tubes, but we already solved this problem in high power switch mode supplies that use the same principle: active or passive PFC can be designed into equipment to remove this current distortion, and is often required for certain classes of equipment at high power levels.

The rest is also technically possible, but a) a well designed audio amplifier using negative feedback has a power supply rejection ratio of a loving ton at the frequencies he's talking about (120 Hz) and b) if you for some reason need more regulation you can... use a regulated power supply.

I'd love to hear what amplifier had a 30% reduction in power from a 1-2% mains voltage drop, for that to happen it would have had to be right at the clipping point, and let's not forget that power companies usually deliver voltage +-10% and basically no distortion-spec.

If yall are serious about starting a thing to prey on the weak-minded (but rich), my business teacher has a ridiculous amount of China connections and could proto stuff for insanely cheap. I actually mentioned it to him and he doesn't want to get attached directly because of the immorality of it (the way I pitched it was sell 100 $5000 power cables and walk away) but he'd have no problem being a middleman.

Really, just hype the poo poo out of something for a month or so on a couple other forums, whip up a site with 3 discontinued (fake) products and a new, improved, top of the line one, and disappear when we're rich. That's all it'd take. I could probably do something in wordpress like, tonight, if someone could CAD up a few progressive models and one to send to China, and we'll all be worth 6 figures by July.

Sound insulation/paneling would work best, since it can make an actual objective difference to a listening experience when dog barks or thunderstorms are muffled. The only issue with morality is just how high the markup is, but that bad feeling can be negated with extra business for others by advising cusomters to solicite the services of a local a carpenter to install it.

This is why you're not allowed to talk about double blind testing - it's Schrödinger's cable. It's simultaneously the most amazing, incredible audio experience, and not. Testing it would collapse the waveform and ruin it!

Pretty much every well reviewed headphone out there has its own "house curve" built in anyways. They measure +6db or so down low and gradually roll off above 8khz or so to -3db or so buy the upper end.

Given how close the speakers are to your ears, this is pretty much in line with what Dolby, THX, Audyssey and others do when calibrating a home setup versus a large commercial venue.

Post the results if you do. I'm honestly curious.

I spent last night toying with a Fisher console stereo from 1963. Apparently I'll be inheriting it from my grandma when the time comes. The cabinetry is in great shape, but the electronics are going to need some work, and the foam surrounds for the speaker drivers are obviously dead, given their age. The biggest thing for me will be figuring out how to get rid of the nasty 60 hertz hum.

In the end, it should make a nice piece for our master bedroom.

I wonder if they're going to include a high quality audiophile grade USB cable so no bits are lost in transferring their files...

*edit: Actually in the comments there's people arguing over whether or not you'd be able to tell the difference between a flac/wav and a 320 mp3 "on a decent pair of speakers". I have an entire rack of kit for my PA which enable me to run the system completely flat from 30hz-20khz. I've played MANY mp3 files on it and compared them to wavs and flacs at high volume. I noticed no discernible difference, certainly gently caress all to care about.

...so what do they mean by 'decent' speakers if a flat system gives up very little in terms of difference?

The funny thing is that they argue like mad, but no one thinks to do an ABX test and find out for sure.

To be fair, there's more to good speakers than just frequency response. Phase coherence, impulse response, those sorts of things. It's very possible to make a speaker system or setup that responds within +/-1dB to any sine wave between 20Hz and 20kHz, but sounds absolutely awful when playing real material.

Luckily, a better-than-decent set of speakers don't have to cost an arm and a leg. I paid ~$800 for a set of Adam A5Xs, and apart from rolling off around 50hz due to their size, they are firmly in the "very good speakers indeed" category. They reveal errors in mastering so well, and if any shortcuts were taken during recording, they will find them. I admit it's a tradeoff, because while well-mastered material sounds amazing, badly mastered material sounds like exactly what it is; badly mastered.

And even using these high-quality studio monitors, I am unable to discern a difference between FLAC and 320kbit MP3. Same thing with my studio-grade headphones. Same sensitivity to bad mixes, same complete inability to discern between FLAC and 320kbit MP3.

E:


Speaking of 320kbit MP3:

quote:

Beats get you kicked out of any recording studio – at least for laughs. I use Klipsch Image S4 headphones for my iPod. They sound pretty good since I run all of my audio at 224 kbps VBR through my nano (otherwise I try to keep all audio at 320 kbps on my PC). But even at 320 kbps, which is the best you’re going to get on audio CDs that you buy from any store, it’s still compressed audio from the original WAV recordings. Granted, running the native WAV files would mean each song would probably average 40-50MB each instead of 7-9MB @ 320kbps. Still, the lossless audio does make a noticeable difference as long as you have speakers or headphones capable of reproducing it. So for Skullcandy and Beats owners, this really wouldn’t be the device for you. If you do happen to own good headsets from Bose, Sennheiser, Sony, etc. or are running studio monitors for speakers, this device would be phenomenal. I personally would be interested in it but I’d have to try it first. I’d keep my iPod for gym visits or running and I would potentially use this device for home audio. Hope it gets traction.

How is it possible to be this uninformed and ignorant? :psyduck:

At least some of them get it:

I know it's not in context here, but I really dislike automatic Bose hate. They aren't accurate and boy do you pay for them, but they have been doing the active noise cancellation game longer than anyone; so, if that's what you need,I always recommend them first.

I didn't care for them until I sampled a pair of QC320s in Dubai before a 12 hour flight. That was the most bearable time I'd taken the flight from Dubai to Atlanta.
