Ron, You ask a question that is quite subjective and each will have an opinion. However, since you already have a K3, you can evaluate the 'how it sounds' question with your own K3. Just use the WIDTH control to narrow the SSB response to 2.1 kHz (you may have to move the SHIFT to maximize intelligibility) - listen for a while and then try the 1.8 width the same way. The roofing filter will sound about the same as you obtain with the DSP, but the roofing filter will keep the Hardware AGC from reacting to extremely strong near-in signals - that is the benefit of the roofing filter.
