Most K3 users will not notice, nor benefit from, a lower AF cutoff in DSP hardware. Our most recent firmware already lowers the response somewhat. Those lacking spectacular hearing and an application for ultralow bass can forego the upgrade.
I have an original DSP in my K3, and I find its bass quite satisfactory even for ESSB and for listening to music broadcasts. OTOH, I prefer rock and blues. Maybe if I were listening to classical I'd need those big electrolytics :) 73, Wayne N6KR ---- http://www.elecraft.com ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
