A Transport of Delight: CD Transport Jitter Page 4  After
measuring the first two products (the PS Lambda and the
Panasonic SV-3700), I went back and repeated my measurements to
make sure the analyzer was giving consistent results, and that
my test setup was correct. When I remeasured the SV-3700, I got
about half the jitter than when I first measured it!  What
caused this reduction in measured jitter?  Changing the
direction of the digital interconnect between the transport and
the jitter analyzer.  This phenomenon was easily repeatable: put
the cable in one direction and read the RMS jitter voltage, then
reverse the cable direction and watch the RMS jitter voltage
drop. Although I'd heard differences in digital-cable
directionality, I was surprised the difference in jitter was so
easily measurable—and that the jitter difference was nearly
double.  To confirm this phenomenon, I repeated the test five
times each on three different digital interconnects. One was a
generic audio cable, the other two were Mod Sq
