But hey, we must have been imagining it all as we all know there is no
difference between competent amps, cables, CD players, components,
stands, spikes, cones :-)

The snag here for me is that any effect due to changing cap type may be due
to some process like the interaction of the cap's external fringing fields
with its local environment. This will depend on the amp layout (including
the wiring loom) as well as the nominal circuit diagram topology. As a
result, any deductions drawn from testing in one example of an amp may not
tell us anything about what might happen in other amps. It may also be due
to 'undesirable' effects which can introduce problems that go undetected in
a listening test.

We also would need to take care to ensure that the values/properties chosen
are close enough for a comparison to be 'fair' if we are trying to
determine a specific hypothesis - e.g. that it is the dielectric that is
having an effect. It is one thing to feel that a change of component has an
effect. It is something else to establish a physical mechanism.

Had a great late night session last night
till 5am, the music just sounded better and better as the night
progressed... which may have been due to certain beverages :-)

I think I know what you mean here.... But further experiments may be
required to pin down the effect. ;-

Slainte,
