I have 2 Sony 985 400 disc megachangers.
It actually works quite well.
It did lose one feature from older Sony megachangers. It will not play both sides of a DVD10 or DVD18. You have to take the disc out and flip it to play the other side.
It has buit in dolby digital and DTS decoding and SACD.
The only real negative is when playing regular CDs. There is no dynamic range to the sound.
The disc explorer allows you to organize your DVDs.
It is currently on sale at Vanns for $359.
