The problem is you have to have a good system to perform valid tests. So, what was the set up? |
It is all described in the pdf that I linked to above:
"The ABX methodology requires device A and device B to be levelmatched within ±0.1 dB, after which you can listen to fully identified A and fully identified B for as long as you like. If you then think they sound different, you are asked to identify X, which may be either A or B (as determined by a double-blind randomization process). You are allowed to make an A/X or B/X comparison at any time, as many times as you like, to decide whether X=A or X=B. Since sheer guessing will yield the correct answer 50% of the time, a minimum of 12 trials is needed for statistical validity (16 is better, 20 better yet). There is no better way to determine scientifically whether you are just claiming to hear a difference or can actually hear one."

Without a minimum of neutrality and transparency on the system, these tests means nothing.

Yes, that's what i meant. I don't speak about theories and mathematical formulas, i don't mind about it.

That's a typical example for audiophile logic. They refuse ANY listening test anywhere else but at their home, which is not practical.
The whole discussion is laughable anyway. Why should anyone invest ridiculous amounts of money in systems which even audiophiles cannot tell apart from standard hifi components under neutral conditions? Even if these systems really had a better sound quality, the difference is so small that it cannot possible be worth that money.
Remember that one can enjoy music even with the crappiest equipment. Listening to music on a 100,000 $ system will give you more joy than listening to music on a 1,000 $ system.

"Why should anyone invest ridiculous amounts of money in systems which even audiophiles cannot tell apart from standard hifi components under neutral conditions? Even if these systems really had a better sound quality, the difference is so small that it cannot possible be worth that money."
Its the kind of argument of someone who has never heard a good system. And thats normal.
But by a simple listening, some of your bright theories would collapse in 30 seconds.
"Remember that one can enjoy music even with the crappiest equipment. Listening to music on a 100,000 $ system will give you more joy than listening to music on a 1,000 $ system."
True if systems are good and musical for the price.
I have never said that you can't enjoy music at all without good equipment.
I'm just trying to explain that it exists good things in Hifi which allow to have more pleasure and emotion with music than on a standard system.
And the differences i'm talking about are not small.
For example, compare the vague buzz that can makes a bass line on a normal system, and the powerful, deep but tense low that can provides a good sub -well fitted and well feed on power-, as if the bass player is in the room.

192kbps mp3 file on headphones is PAINFUL to listen to...i can't get it why ye dont see the TREMENDOUS difference. 
Ive played the same Music file ripped from cd at 192kbps on a mp3 player that costs TWICE as much as my discman with the same headphones(Or just standard earplugs) and the general loss is so big i will never listen to a mp3 file ever again using HEADPHONES.
On my pc speakers i however dont mind playing back mp3 files at 192kbps...but with headphones where you can really hear all the details it is just a PAINFUL listening experience...
If not anyone hears a BIG difference from cd to mp3 192 they have to be deaf

So you would agree that I can enjoy music with my Harman Kardon system?

Maybe your headphones are too good.

I never said that there is no big difference between 192kbps mp3 and CD. I just said that I can life with that difference. Others may not, and that's their decision. But I'd appreciate if you could accept that I can enjoy music on my mobile player, in that format.

You should asked me this question before!
Yes, you have half of the music, but you enjoy it.
And your brain works to reconstitute the informations missing. It may involve a headache, although.

aha - we seem to agree, but we don't. I have all of what's important of the music with mp3, although it sounds slightly worse. Of course I know how mp3 works - parts of the signal which the human ear can't hear are left out. The result varies from signal to signal - some songs may sound really ok, others may sound harsh or "bland". But the higher the bitrate, the less are those effects on the signal, and in my humble opinion at 192kbps it's barely audible in a mobile situation (bus, train, cycling, jogging).
That's my opinion, and it's different from yours. Nothing wrong with that!

We agree actually, except on the "slightly worse".

it amazes me that anybody that are used to be listening to cd's and then turns to mp3's are not annoyed by the tremendous loss of quality?
Its like being used to driving a ferrari and then start to drive a fiat instead...
