We have long been a fan of Kenwood, so it is nice to see they are offering a compact system. The UD-E77WSD has a CD player and SD slot for 32GB cards and a USB port for downloading tunes from your other SD cards or DAP. The system supports AAC, WMA, MP3, and WAV files as well as 24bit DAC high resolution sound. The player features Kenwood’s Supreme Technology and comes with a remote that is probably more difficult to use than the system itself.
