[Elecraft] K3 question to those who have upgraded their DSP board

[Edward Dickinson, III]

>Has it improved fidelity? Reduced noise? ...Speaker or headphones?

...Line Out?

I ask as seemingly on the reflector I picked up that (LPF asisde?)
improvements to the DSP board audio affected the Headphone output.  The
improvements to Speaker and Line Out were those made on the main board.
 
If the above is the case, does the LPF affect ALL audio outputs?

Will Elecraft or someone clarify this?
