I enclose the following, from Geoff Mead (Audiocircle): does anybody know
anything about this? Quote goes:

Re the current thread on speaker cables and sonic differences between
different amp/cable/speaker combinations. There has been an interesting series
of articles in Electronics World staritng June 2004 if anyone hasnt seen them.
The author Graham Maynard started looking at the old chestnut as to why valve
amps sound different from S/S ones particularly when played loud. To cut a long
story short he proposes that Miller compensation and series output inductors
are responsible in causing what he calls First Cycle Distortion. His
proposition
is that the reactive impedance characteristics of most loudspeakers interact
with s/s amps that have these features over the first cycle of each frequency
component that makes up the music waveform. He suggests that these effects
disappear after the first few cycles and therefore do not show up in pure sine
wave testing. An interesting conjecture, yet to be fully proven, but the point
is that
the reactive elements of connecting cables would also figure in this argument.
If this were true then valve amps should be much less affected ( SE types
excepted?) Geoff Mead
