MPC (and Ogg and APS) problem clip

MPC 1.02, --standard

Smoke City - Underwater Love

from 17-20 s there are vocals 'This must be underwater love'

The 'this-s-must' sissing sound gets exaggerated by all
codecs. The artifact is amazingly similar.

I can ABX Ogg -q5 and LAME APS 16/16, MPC at 22/32  (<2.5%)

Please don't use FLAC. It do not work properly.
I tested compiled source and binaries with the
same result:

Official 1.0.2 Flac worked just fine for me.

And yeah, there is amplified sibilance(s). I did some blind test rounds with WinAmp. (Didn't bother abx since Garf already did it, and the case seemed pretty clear)

Is there a static linked Linux/IA32 binary?
Comparing the average trouble I have with
dynamic linked files with the prices of
current harddisk I would prefer a complete static
linked system. And it comes worse after the next system upgrade.

Used equipment?
Age?
Soundcard should not be the Soundblaster Live!
Dolby Pro Logic II?

SB 128 PCI (es1370) -> AKG K-401

My HD560II I have currently at work.
Defects in the range 3...5 kHz are easier
detectable with the HD560, 8...14 kHz easier
with the AKG-401.

May be I should by the HD580 too.

BTW. I have problems with the "be" - the "e" vibrates, not with z-tones.
