[Elecraft] Which audio filter???

[Fred Bennett N9TA]

 Hi Gang

I "was" the proud owner of K2 #242......but I sold it a couple
of years ago. Now I am contemplating jumping back in and
building another K2 with all the options.....but I have a
question for the group: Which audio filter to get....if any???
My old K2 had the SSB, NB, low pwr tuner, amp, and 160M
options but no audio filter. And now there are 2 to choose from!!!
I've had many radios with DSP and I generally end up not
using it.....but I fully expect Elecraft DSP to be superior to
that found on the Yeacomwood rigs.

Do I want an audio filter???  And if so.....which audio filter???
