I don't mean to say that the 808 is inferior to the N900. It's just that with my setup the 808 sends music via BT to cheap device, cheap device processes the signal and transmit it via FM, the double processing will inevitably degrade the sound quality. I think if I used the N900 with that cheap device the results will be similar to the 808, and will definitely not sound as good as direct FM from the N900. The sad thing is that my 808 was bought in HK and so the FM transmitter was disabled.
