[Elecraft] K2 DSP vs. Audio Filter

I owned the 570 Kenwood and agree with you.
I own the PROIII and the K2/100 with the DSP option and here is what I found: The Icom when listening to SWL or AM BC is nicer since you can go out to 9 K but in real world listening on the ham bands the K2 has a DSP that is at least as good as the PROIII and the noise blanker, at my QTH anyway shows the K2's NB winning out, although the Icom NB works good too and in fact a lot better the original PRO I had. If you want BC sound coming from your speakers then the K2 is not what you want, but if you want a radio that hears really well with a knock out filtering system using DSP, the K2 works great. I couldn't believe how well the DSP performs when I first tried it, and on weak signal work using the DSP doing A&B tests the PROIII versus K2, it's a toss up.
Good Luck

I've had experience with audio filters, but not DSP. Actually now that I
think about it, my TS-570DG has an audio DSP filter of sorts. I strongly
dislike the audio coming out of it as harsh and grainy.
I've listened to the demos for ssb and cw on the Elecraft site for the DSP
filter. The noise reduction is dramatic, but the audio sounds, well,
digital. If the K2 is as quiet a receiver as I've read, does the DSP trash
up the received audio? And how does it do with power line noise?
I would be interested in anyone's comments and impressions of these two
filters in real world operating situations, even though they are apples
and oranges. Is DSP worth three times the money in your opinion, and why?
