Anybody looking at this player? It might be a good one for Rockbox as their tech specs are high:

The excellent 24bit/192kHz sound quality is largely due to the single HiFi DAC (Digital-to-Analogue Converter) that has been used inside the Pocket HiFi C4. Wang team who designed the Colorfly Pocket HiFi C4 Pro decided to use the CIRRUS logic CS4398, a high-end chipset usually only found in top-of-the-range HiFi components. This DAC offers outstanding levels of performance with excellent dynamic range up to 120dB and the ability to decode 24bit/192kHz audio .

• ADI AD823 chip
• CIRRUS LOGIC CS4398 DAC chip
• CIRRUS LOGIC CS8422 SRC chip
• TCXO high-precision crystal Oscillators

I think a hardware resampler chip and an RF amplifier is a pretty useless thing to put on an mp3 player. 

I hadn't heard of the player, but their website helpfully has board scans:

Weirdly, they have a an Altera FPGA module, which is also not something I would expect to see on an mp3 player.  I guess the processor is the chip labeled "C4 Master".

Would it be possible for you to elaborate in a way the less technically trained (like me) can understand this?

Its got a bunch of hardware that isn't really needed or useful for an mp3 player.

I guess I was hoping for something between those two extremes :)
