Why not ALL formats, DVD-A, HDCD, SACD, Redbook. I would look at Denon 3910, modded by either, APL, Modwright, Exemplar, Allen Wright. All will give much better sound, and bang for buck. Buy it pre-owned and they will retain value. I have owned more than 50 digital sources, from 500-40000, and by far, the best is, and were the modded players. You may even walk away with A new CD collection for the difference between the 4k, and whatcha pay.

BTW, DVD-A is quite amazing, as well as HDCD, but, the best surprise, will be how great the redbook sounds
