After reading these 5 reasons I can understand that audioholics is running a cult...
The greater good.
"Equipment Differences"...I already explained that you can't hear anything good with $20 computer speakers. I use expensive sony BT headphones with my laptop...I don't use cheapy computer desktop speakers...
Still, there are limits to what your Sony BT headphones can reproduce. Complex polyphony can be challenging to single-driver cans, and might result in harmonic distortion that isn't measured with frequency sweeps, or might cause the treble to become choppy when sub bass is also playing. The videos you hear on YouTube will not overcome these problems, nor will they calibrate nor improve the head related transfer function of your Sony cans.
"Room Acoustics Differences"...I understand this to some degree but it's no excuse for everything north of 300 HZ. Maybe Audioholics does this for legal reasons alone but this should not prevent them from doing video demos.
This, plus the next point, are bigger problems than you realize. If you clap your hands in whatever room you happen to be in, how long does it take the sound to decay? A quarter second? At least with headphones you aren't combining your own room acoustics with those of the recording. But the recording cannot do the impulse response of whatever speakers you're listening to any justice. How much is the acoustics of the room coloring the sound? Below 200Hz notwithstanding, does the recorder's uncalibrated mic bring the treble forward?
"Microphones are Stupid"... The microphone on the other hand will just sum the direct and reflected sounds together ...This is fine...I'm ok with a quick demo and Understand this is happening in the demo. There are recording techniques that can alleviate some of this, but it takes multiple mic setups, DSP processing and knowledge of how to use. Most YouTubers are simply NOT going to do that. We certainly aren't.
I'm not looking for perfection from a youtube video. I'm looking at the general performance of different types of speakers (Electrostatic, ceramics drivers, paper drivers, AMT tweeters, etc.. I only really pay attention to individuals who do a good job of recording.
The sort of subtlety you're hoping to discern can't be achieved by listening to a recording of a recording. You said so yourself with your photocopy illustration earlier. There's too much loss of detail. And again, how can you hear whether the mic is combining direct radiation with early reflections to color the sound? These room interactions might not occur in your own house. Or there might be different interactions not heard by the videographer.
"YouTube Compression"...Garbage in garbage out...I use Netflix streaming service and I get spectacular audio from netflix shows...Netflix uses compression also but if your equipment can process the audio back out it should sound fine. Given that the audio sounds fairly good on youtube I'm wondering if this statement was made years ago.
I will concede this point. I'm not one to drink the 24-bit, 192kHz Kool-Aid either. I believe 16-bit, 44kHz, 224kbps MP3s are indistinguishable from lossless, and can only very rarely tell the difference between lossless and 192kbps. And since YouTube uses AAC, which offers better quality audio compared to the same bitrate MP3, YouTube's compression will have a negligible effect.
Most of our listening demos consist of high resolution audio recordings such as DVD-A, SACD, or FLAC 192kHz/24bit. What the hell does this mean? Most people cannot hear anything substantial past 16 bit cd quality...whether your listening to high res audio or cd quality you should be able to determine if the speakers are operating properly. The crossovers are done correctly and the speakers are not overly bright....
Maybe this was done years ago and audioholics needs an update....
I'll add a few more to the list. Is the crossover point too low for accurate sound stage? Too high to mask the breakup modes of the mid driver? Do the speakers have a wide enough listening window to accommodate your intended use, or is there a single sweet spot that will leave others in the room hearing acceptable but uninspiring sound? Will the off axis response color early reflections differently in the videographer's room than it would in yours? These are questions a YouTube video cannot ever answer.
