Well, I just got mine and it really does sound like a 'HAL-9000' type device. It sounds kind of cartoony with a white kind of texture, not too bassy (compared with the S9 on BBE Headphone 1), and clear, as well as more sparkly on the top end. I like it. It's probably my favourite device to date because of the micro sd feature and how I can compile about 3 gigs of uncompressed WAV files on one 16G card compared with 1G of Hi-sp on my RH1. The BBE feature is really good too.
Uh, why can you only put 3GB of WAV's on a 16GB card? And why WAVs instead of FLAC?
