I wonder how much of this effect is capacitive loading on the output
of the amplifier and how much is due to lower impedence of the cable.

It would be interesting to see how it sounds when you connect up the
system using the normal cables, and just connect the  monster cables
to the amplifier end (thereby still increasing the capacitance that
the amp must drive, but keeping the cables impedence the same).

Most amps tend to ring a bit when driving a slight (~0.1 uf)
capacitive load and break into a full fledged oscillation when the
capacitance is increased (around 1 uf). Ringing certainly adds a bit
of high-end sizzle!

I use 12-guage multi-strand tin-plated wire for my 4-ohm speakers. The
cable impedence is vanishingly small compared to internal impedence of
most speakers. Most importantly, the cable is *cheap*.

I did weave some of this into a 2x4 wire 10-ft braid (lots of wire)
into an attempt to reduce impedence. The net result was
mega-capacitance. My poor amp output was phase-shifted back so far
that its feedback loop was quite a bit less stable.
