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

[K2MK]

I've noted several recent postings from those that have upgraded their DSP 
board (which I assume included the LP filter board). Each has said that the 
new board sounds great. I wonder if those folks could be a bit more specific 
in order to help those of us on the fence. Has it improved CW or SSB? Has it 
improved fidelity? Reduced noise? Speaker or headphones? Any other thoughts?
