Read it again.I read somewhere (earlier on this thread I think) that a 200gb SD card does work in the plenue D, but only if you’re within a file limit of 16,000 (I think).
The player won't crash if you put in a larger card. All your music will show up in the library and in folder browsing. However, when you go to play it, only files located within the lowest 128GB (or thereabouts for the pedants!) will play. Any file located further along on the card will not play. You just get file not found.
This is the only reason my PD has been relegated to the bedroom for late night listening and I now have a Shanling M0 which is brilliant for out-and-about use.
In defence of the PD, it is doing a great job bring some 'life' to the LCD-X (which sadly failed to replace my T1 as prime headphone on the iFi rig). PD + LCD-X sounds way better than you might expect such an apparently mismatched pair to sound but only after tweaking the JetEffects.
