Hi Zaphod,

You could be right, but in listening to something with very quiet passages, I am more aware of the hiss on the M6 than any 'clamping' on the Rockchip.

The M6 is however totally silent when the vol is at zero, or when you press stop / pause. It seems to mask it's [possible] inherent hiss-iness by shutting off all audio output in these states. in going from vol=0 to 1 on a quiet piece of music, I notice the hiss immediately - it' not overwhelming, but it is apparent.

I should say that my Rockchip player wasn't perfect 'out-of-the (non existent) box'. It came with no software at all, and initially, I had to use the aviconverter software which came with my first 2" Rockchip player. I remember I was a little disappointed with the results.
However, when I stumbled across the DVD2MP4 converter from Xilisoft, I found a product which works in perfect harmony with my 2.4" Rockchip player and the video results are stunning - and consistently in sync. It might not be ideal for some, as it's quite pricey ($44 I think).
Unfortunately though, the Xilisoft product doesn't work very well with my M6 ! The videos are very jerky and tend to bomb out. I will have to ask them to write an M6 profile!
If someone can advise the perfect solution for creating movies on the M6, I'd be over the moon and won't need to ditch it on Ebay!

As I said earlier, I am not out to destroy the M6's reputation - it IS very good....but there are aspects of it, as already discussed, which don't seem to match the Rockchip. I am going to source another Rockchip soon - perhaps the version I have is uncharacteristically 'brilliant' - but I suspect all 320x240 units with the 'tabs across the bottom of the screen' menu behave the same...???
