I ordered a KAF2 because I prefer the sound of an analog filter the digital, on CW I find it gives it a funny tone, almost a "twerp" sound, and I do not like what it does to the voices on SSB. So I went with a normal KAF2 filter system. I have a DSP filter on my normal rig, and dislike the sound "effects" it produces to people and CW, sound like they are speaking inside a barrel or tube. But then I am partial to my older Tube rigs that I have restored, to me no better sound on voice then one of those guys..
