Hello:

I have an Ultra DAC based Roon/Nucleus+ based system. Currently use a $300 Sony UDP-800 for CD and DVD. How much of an upgrade sonically and visually would a mint preowned 500 series player bring to 2/3 channel and to HT Surround sound? The 800 series is out of my price range, considering I only do CD 10% of the time, and HT likewise.
