My point still holds in that nobody serious builds LCR filters for
auido (speaker crossovers exempted). His LCR filter IS in the audio
chain, not the IF.

Your comment that "nobody serious" is so off base as to be asiniine.
Dallas Lankford is clearly one of most serious DXers alive today.
Why not take a look at all the technical information at

before jumping to silly conclussions.

I've done (as in been paid for) filter design in telecom/datacom
applications, including elliptic filters, delay equalizers, etc. I know
of what I speak.

There is a leapfrog design on this page if you want to educate
yourself:
