Well .. I'd get a headache listening to most ANYTHING after 4-5 hours.  The 
symphony in Bass Hall, or even good vinyl on a great turntable/arm/cartridge 
and a very good amp and very good headphones is no different.  

Maybe I just found the "right" speakers for my K3.  They're old RatShack (RCA) 
speakers with linaeum tweeters.  I have a lot of them, and use them on 
everything (new, old) in the shack.   I've never  found a powered set of 
"computer" speakers worth bothering with ... and I've tried quite a few not so 
cheapie ones, or the usual-suspect ham speakers.  I haven't tried the Elecraft 
offering yet, but probably will at some point. 

After the LPF daughter-board update (or rev D DSP) I haven't had an issue with 
anything related to K3 audio.  And certainly nothing I'd call a "screech".   
The internal speaker is the speaker of last resort. My RX EQ is set to flat. 

That said, I'd still probably buy the updated DSP board for the improved IMD 
performance. Just because ....
