Koji plejer daje najprecizniji zvuk?

Jedan izvor kaze ovo:

Since what the MP3 standard really defines is a decoder, there should be no such thing as a better or a worse MP3 decoder. As long as a decoder is accurate, it'll output the expected quality.

All the most popular decoders these days output accurate enough streams. These include:
Winamp's FhG decoder
mpg123, probably one of the most popular decoders, also used in foobar2000, Otachan's winamp plugin, LAME and countless other MP3 players
MPAdec, a very accurate decoder based on mpg123
Apollo, the most mathematically accurate decoder
MAD, another very precise GPLd MP3 decoder
A MAD input-plugin for WinAmp is available in this HA thread

Using any of the above should be enough for all purposes. Quality differences among them are insignificant.

Drugi izvor kaze da ipak postoji razlika, ali cini mi se da su vezane samo za bite, tj dinamicki opseg, ne za frekvencije, tj bojenje signala.

The results for Apollo 37zm 24-bit output are RMS level 7.169?10−10 and maximum difference 1.192?10−7.

For comparison, the same values for the latest MAD decoder (MPEG Audio Decoder 0.15.1b) built with accuracy optimizations enabled and 24-bit output without dithering are RMS level 8.804?10−8 and maximum difference 4.768?10−7. The difference is quite obvious and favorable to Apollo: RMS level is over a hundred times the one produced by Apollo 37zm and the maximum difference is four times the one by Apollo (interestingly the results for MAD 0.11.4b seem to be somewhat better than for the latest one but they are still worse than Apollo's). Actually, the maximum difference of Apollo's output is the smallest possible deviation in 24-bit data, the only smaller possible value would be zero. This means that at any time, Apollo's output is either exactly the same as the reference output or differs from it by the smallest unit expressible in 24-bit data. Of course, this only goes for the provided test signal, but it should give some picture about the sound quality.

Koliko ja mogu da zakljucim iz ovoga, razliciti dekoderi, ne daju isti dinamicki opseg na izlazu i imaju razlicite najmanje razlike nivoa, tipa jedan ocitava razlike od 0.01 db a drugi 0.04 db , tj. jedan dekoder kao sto pise gore u tekstu 4 puta preciznije ocitava razliku u nivoima unutar pesme.

Bas me zainteresovalo ovo pa sam se bacio na istrazivanje

Kad sam otvorio post mislio sam da je besmislen i da razlika uopste ne postoji, ali izgleda ipak postoji, sad, kolika je objektivno i koliko je cujna subjektivno to je vec pitanje.
