The Quad manuals say that an ESL is between 30 and 15 ohms from 40Hz to
8KHz.
** The manual is simply not correct.
It should therefore be about 6 ohms at 18KHz.

Ringing suggests a resonance or rising frequency response,

which would be> caused by series inductance and the ESL's capacitance, and
doesn't fit
with Phil's severe high frequency loss.
I suppose I'd better get measuring, analyzing and plaiting my own cables.
