I just want to point out that the diyLOD isn't carbon copy of Griffin dock, so that could account for audible difference (beside the fact that LO and HO are different, see below*). In the Griffin dock, there are decoupling SMD caps (220mF, 6.3V) in both L/R channels and 100K resistors bypass (downstream of caps). Both caps and resistors are not included in the current V1 diyLOD (no place to fit anyway).
I am not sure what the resistors are for but I'll include decoupling caps in the V2 diyLOD once I got my Ridax connector - no SMD of course, I'll use some Panasonic audio caps instead. I have ordered a Griffin dock as well, just so I don't have to play with cable when sync. I'll make a comparison once I received it.
*Also, I have re-read all the previous comments made on the original LOD thread at Sansa forum and exchanged some PM with sansafix on the Fuze's hardware detail. He has confirmed most of the points I made in post #2, plus some more. I'll update the thread when I have the time to sum everything up. So stay tuned.
Maybe the caps and the resistors are there for some protective reason because the dock also charges the Fuze as it plays.
Hey I have a question: When you jumper the pins to supply the necessary voltage to enable the line out, how does it effect the battery and the charging circuit?
Anyway, I'll be interested in your impressions of how the Dock sounds when you get it.
