Can you perhaps suggest a few recordings on which absolute phase is easy
to hear?  I have several stereos, ranging from a Rotel 955 driving a 
Musical Fidelity A-1 20WPC pure class A integrated amp with a pair of
Chartwell LS3/5a speakers to one that includes the latest revision models
of EAD transport & processor, Threshold amp, and Apogee Stage speakers
(this week, anyway) and several others, including ones where I have designed
the speakers and some of the electronics.  I can hear the difference when
moving a tweeter forward or backwards an inch or two when making
an enclosure, the (frequently dramatic) difference between two high-end
amplifiers, the effects of changing speaker or listener position by an inch
or so, and the differences between different op-amps, but I've never been
able to detect absolute phase, even on the Stereophile test disks that are
specifically designed for testing this ability.
