I've had a D50 since it came out, but haven't used it much as I really love my Sonosax MiniR82. The MiniR82 has spoiled me for most other small recorders, as it can run 5 hours at 24/96 without touching it, close to 10 hours with a small external power pack. Only the D50 does this (with seamless track breaks at 2GB instead of 4GB).
Recently I have had a recurrence of a weird problem with the the Sonosax, a R/L channel swap while recording, and have to send the machine back to Switzerland for repair. This has turned me back to looking at the D50, but I have been a bit nervous about the sound quality given that Sony has stated that the preamp and A/D are not as high-end as the superb D1 (which however can only do 2 hours at 24/96 unattended, since it won't take memory sticks bigger than 4GB so far as known). I was testing the optical-in signal from the Core Sound mic 2496 (Version 1) and found the recorder saw it at 24/48 instead of 24/96, but that the clock on the D50 was running double speed (and a 16GB memory stick pro duo card went from space remaining 7 hours + to 14 hours +). So I'm pretty sure it's recording correctly at 24/96. I recall reports when the D50 first came out that it had this problem with 24/96 signals from some high-end A/D too.
Does anyone know if the recordings made this way are okay? Also, what is a simple way to edit the wave headers to correct the header so that Wavelab, etc., sees the file as 24/96 instead of 24/48??
