[Elecraft] K3S audio board for K3 upgrade?

[Gary Smith]

I so agree.

What I use are a pair of speakers with a truly flat response all the 
way from 80 Hz to 22 KHz but extreme overkill...: Mackie HR824 
powered Studio monitors. They are perfect to me and extremely flat. I 
already owned them because I used to do recording. In this vein, if 
you can find a cheap studio monitor on fleabay or wherever, you will 
surely love it with your K3s/K3.
