Since the K3 AM roofing filter is 6KHz, I guess it won't be so hi-fi. It isn't tubes vs transistors, so much as IF coils vs crystal filters.
Brings back memories of when I was a kid, when I used to listen to AM radio using a home made crystal set with an OA91 diode, tuned by a permeability tuned core. With selectivity that broad, fed into a transistor amplifier, the quality was great although I could hear the 9KHz heterodynes from the stations either side.
