I just switched from a FiiO X5 2nd Generation to the Cowon Plenue P1. One of the main reasons i wanted to get away from the FiiO is the buggy firmware and the slow UI. Here are, for me, the main selling points that make me, now after 10 hours of listening, very very happy:
- USB 3.0 support. No more "remove the MicroSD card, insert it into the card reader, copy it around, put it back into the FiiO". Copying to the Cowon is fast, soo fast, that i see no reason to remove the card. Given the fact that high res downloads are really slow with USB 2.0, this is a nice, and unforeseen benefit of the upgrade.
- UI and general speed. The system is just soo much faster than the FiiO. database updates take a few seconds, not minutes. The UI is fluid, and very, very rarely do you have any kind of slugginess in using the device.
- No stuttering. With the exact same MicroSD cards that the FiiO seemed to be unable to handle. Yes, sure, maybe i would have found one SD card eventually where the FiiO would not stutter, but my time is more expensive than this.
- Sound. No compare. The warmth, the detail, the "stage" is just amazing. I compared the same songs (Diana Kralls "All for you", Bob Dylans "Blood on the Tracks", Rush Sector Two, and Mussorskies Picture at an Exhibition, Susan Wong "Woman in Love") for a few hours, and there was nothing i liked better on the FiiO compared to the Cowon. Everything is just a step up, i feel like finally having reached portable "HiFi", and not just portable "good sounding music".
Note, the Headphones i currently have with me, are Oppo PM3s, so your mileage may vary based on that.
But, me, i am happy having taken that step up from the FiiO.
