Kon, 

I appreciate you as a - most of the time - rationally, scientifically
thinking human. All the more I'm surprised how you can use the above sentence:
"little warmer..."

I was always ascribing this terminology to audiophile woodooists.

What is warm sounding? 

Why not make an MP3 to let us compare "before" and "after" and do a 
Fourier transform on the sound samples after such a rebuild.

No offense meant :-)
