Only just owned the IT00 for a couple of days, and while I like it a lot, here are some things that could be better about it, IMO (Just to counterbalance all the positive reception on this thread :)) - Sub-bass notes could use a bit more punch and separation. The bass line on the Persona 5...

I don't use a playlist, I just pick a song from Category > All Songs, enable shuffle and let it play. If you have scanned the SD card, it should play all the songs in random order.

Got the Pro82 V1 (because reputable local seller only has this version), pretty happy so far except for the 5k peak of the V1. Decided to try EQ-ing it a bit to be closer to the V2s. Here's my current parametric eq setting: 4900 Hz, -10 dB, Q 7 9000 Hz, -3 dB, Q 3.5 3357 Hz, +4 dB, Q 4 << only...

They should really implement scrolling acceleration, just like in Rockbox. Holding the scroll button longer increases the scroll speed. I mean, they did advertise that this player can support SD cards up to 2TB, after all...
