Excellent!  I've long worked in pro audio. When Time Delay 
Spectrometry (invented by Dick Heyser at JPL in the 70's, 
manufactured as an instrumentation product by Crown International in 
the early 80's) gave us the ability to measure the complex phase 
response of electroacoustic systems, we quickly learned that PHASE 
is a FAR more sensitive indicator of circuit behavior than 
amplitude.
