Gapless playback is being worked on and should be in the next firmware update. As for retailers well we have it available for demo in the Midlands, there is a dealer near Kent who has them available for demo too. It's only been un UK since May so dealer base is still being built up. Don't let the description on the site put you of it was written by a Korean so i's not perfect English! If you want a better description then just visit our site.
We have been very impressed with sound quality especially considering the price. The amp is good but using your existing system will gain better results. For best results we have found using Toslink out into a decent DAC gets the best results. Especially if you have ripped it into uncompressed WAV, MP3 and FLAC playback is very good too.
If anyone has any questions about the X10 I woul dbe happy to try and answer them for you.
