Hi guys,
Here are some pics of the D2000 cable and the D7000 cable to compare. D2000 on the left and D7000 on the right.
First one shows the different copper. The pic doesn't cature it that well, but the D7000 wire is softer, more flexible and is more orange/pink than the D2000 wire due to its increased purity.
Other pic shows the differences between D2000 and D7000 sheaths.
We don't deal as much in D5000s or replace as many of these cables these days (we use the D2000 and D7000 primarily), but still have not seen D2000 cable on D5000 so far. We have no special insight whatsoever into Denon/Fostex's manufacturing process, other than the units we handle.
