Regarding:-
"The most curious trait to me in this test is the ringing resonance of 
the 661 and LS-10 "tocks" centered around 250 Hz. They sound like the 
result of a "peak" in Tom's living room but I do not know why this 
phenomenon would not also be picked-up by the Hi-MD recorder. 
Befuddling,.."

This may be produced due to the position of the clock "hand". I couldn't
distingise from the photo if the clock had a second hand, if it did the resonant
low frequency may change depending on its position. I'd guess the
hand was falling for the second two test recordings, but assending from 6
to 12 for the Hi-MD section.

A full 60 seconds from all recorders could be used to determine if this
the cause or not...

Either case, I found the test interesting :)
