Not an explicit one...

Guise pls.

This should be the same moment at the start of the song. Can it be clearly said, that the Audio CD was ripped from an original CD, or can it still be just a bloated 128kbps mp3?

I'm keeping the ATH M50s. Thanks for your advice and suggestions.

Meh. Me don't want in-ears.

There is one last headphone comparation I need to decide, before finalizing my pick: ATH M50 vs V-Moda M80   V-Moda wins in portability, that is clear, but what about comfort (stiffness, clamping force), sound quality (bass oriented)? So far I've been using M50s for use on the go and they...

  It looks as if it really is somehow less lossy, doesn't it? :-)

Call me vain, but HD25/Amperior just don't look right on a head. They look right for what they are suited - professional sound technician use.

Between ATH-M50 and HFI-780 I have to choose M50, because of the build and comfort. Sound quality wise they are bit different. M50 sounds more "fun", bass can get really low, but only if the song requires it. 780 is much flatter and overall more balanced, the sound seems more studio-like.  ...

I'll bet my fresh new M50's it's the crappy Razr. You can't expect good sound quality from a phone. I found that out the hard way - I bought Samsung Galaxy SII and was looking forward to using it as a versatile device, including playing music. However I was soon heartbreakingly disappointed. It...

How can I check for distortion in a certain frequency, when I only have songs? There are no harmonic sine waves...

Shoot. Without the original audio CDs there is no way of telling? That's too bad, but thank you anyway.

I tried doing a FFT of my 320 kbps mp3 and the "unknown-original-format" Audio CD track. The time should be the same, even though it wasn't as easy, since the Audio CD tracks are few seconds longer than my mp3s. Can something be decoded out of this? Is the audio CD track true high quality...

So right now I'm waiting for the delivery of Ultrasone HFI 780 and AudioTechnica ATH M50. Can't wait to test and compare them, but I hope one of them will have everything I'm looking for.

The codec detected by VLC is PCM S16 LE (araw).
