[Elecraft] KAF2 or KDSP2 for K2?

[Johnny Siu]

Hello John,
 
From time to time, there are used KAF2 available for sale in this reflector at a much lower price.  I got mine at US$49.
 
I don't like the KDSP2.  The artifact of the sound is just annoying to me.    This topic was well discussed in the past and you can find it from the archive. 

TNX & 73,


Johnny VR2XMC

Thanks to everyone for the comments and thoughts.

I'll start with the bare K2 (I really don't have a choice at the moment) 
and see how it goes.

Later I will refer to your comments again in the archives for the next step.
