This IS an impressive unit ! ! !
The DENON DN-F400 player reproduces WAV files with pristine clarity! As a gospel songwriter and performing vocalist, this is very important. Even though the unit must play 16 bit WAV files, the sound quality is amazing. I purchased this unit, along with the DENON RC-F400S controller. I rack mounted the DENON DN-F400, purchased a slide out locking rack mount shelf from Sweetwater, and used velcro to affix the DENON RC-F400S controller to the shelf. By going this route, I have completely eliminated the hassle of burning CDs to prepare for my worship programs. I simply place my songs in folders using a 32 G SDHC card that I purchased from Sweetwater. There are twenty touch buttons on the RC-F400S controller that are assignable. Now, I can access any song on the fly! This setup does away with all mechanical mishaps due to the fact that there are NO moving parts! Just think of the money saved on CDs! I am enjoying these units.
