- Unfortunately your source is wrong in his assumtions, comments Lars 
Liljeryd on Robert Voigts statement.

- We cannot see that there are inherent or future limitations in SBR 
when in comes to higher sound quality.

Lars Liljeryd says he don't want to speculate on where lies the 
"sweet spot" of SBR.  He is not willing to supply further technical 
details on how SBR works.
