How many of them has designed an ANTENNA with anything approaching the percentage
bandwidth of an audio system? And how many decades passed before HP produced an RF
generator or analyzer that covered the percentage bandwidth of an audio system?
I'm not denegrating the discipline of RF engineering, but rather observing that
audio can be FAR more complex than RF, and that I've seen some very good RF
engineers screw up badly below 100 kHz. Witness the K3 (which I own and love).
