Yes, I'd like to know also. If it's just a music sound thing, it isn't a problem for me, I don't use it for music, but I know many do.

This is actually a long story but in short

The Galaxy S II uses Yamaha audio hardware. The Galaxy S II's predecessor, the original Galaxy S, used Wolfson's WM8994 DAC.

Galaxy SI has wolfson codec , which was open source.
Supercurio a well known developer and audio expert here in XDA was able to create good sound output using his voodoo app.

In galaxy SII samsung replaced wolfson with yamaha and this was closed source.
The sound quality for audiophiles using galaxy sII was terrible. ( not to my ears as I am a certified non-audiophile )
Being closed source no further development was possible.

IN the words of supercurio "
DAC Distortion
With today’s Android audio implementation, all kind of media are sent to the DAC as a 44100 / 16bit / Stereo stream. Despite the usage of a fixed rate, Yamaha’s codec is not able to provide a very clean output.

Galaxy S II DAC output quality is limited by several kind of distortions. So far, no firmware was able to fix those despite early Korean updates describing “audio clarity improvements”.

When playing music, those artifacts are perceived as “lack of clarity”, “reduction of stereo separation”, “loss of detail” and “lifeless sound” (opposite of lively)."

The good news is that with new firmware releases many people have said that the sound quality of Galaxy SII is much better. So i guess its going to be better in GNote.
However we wont get Voodoo sounds improvements.

Isn't there a chance that the kernel/software might be slightly different and will fix the issue?

Besides I've got my hand on for few minutes and I didn't pickup anything being wrong with the sound quality. However I didn't have a chance to plug in my headphones so I might be wrong.

Fast answer

yamaha dac is pure crap if you listen music in headphones over 10€

GS2 + note = yamaha dac, so if you want to listen music with a little quality you need a dedicated mp3, the phone will not be suitable for that.

I see no problem with the sound thru headphones.

Honestly, supercurio must have super ears, cause i've been using my sgs2 as my primary mp3 for 6 months already and I have no complaints. But dude, thanks for ruin it for me. I won't see my sgs2 the same again. =(

Lol, there are no facts, only interpretations. BTW Yamaha produces great electric pianos. Don't see how this is relevant but lol, maybe it helps to restore your hardware
