Yes, I think there is a lot going on in the modern stuff, early stages being distorted, stuff getting through the filters, and other sorts of distortion.
I have been into AM a long time, and fidelity there is important, and all the modern rigs sound nasty on AM no matter what filters they have, even with outboard audio amps. The best sounding receivers I had were ones from the 40's, single conversion, push pull audio output tubes. The SX17, the Scott SLRM, they were designed to also be hifi amps for record players... When I did my K2 filter crystals, when grounding them, I used thicker wire, think that helps any? I cant detect anything getting past the filter in my K2.
