Well. For home use, non-portable, network capable, Pioneer makes a UDP-LX500.
It is a 4k machine. Videowise: plays 4k blu-ray, blu-ray, 3d blu-ray, dvd
Audio-wise: plays SACD, cd, dsd, aiff, flac and a bunch of other formats.
I have included a link from Pioneer’s website. From their website “operating instructions” has several pages that list all audio and video formats.
While I do not have this exact model, I do have an older version of this machine (looks identical). I play high-res audio files from a usb flash drive connected on the back of the machine. It is a little tempermental, where I make sure the power is off and UNPLUGGED before connecting or disconnecting anything, including usb flash drives. And after playing a video file from the usb I need to play 2 cd’s afterwards to get the display back onto music. But otherwise LOVE this machine.
It has coax and optical digital outputs as well as rca line-level outputs, and a high-quality dac for the line-level outputs.
