I have had t,he Marantz DV9500 then went to the DVD3910 which I quickly traded in for a DVD5910ci. The 5910 was superior to them all. I see the 5910s for all here once and a while. But a word of caution, these are all older machines and are at the end of their expected life span. You don't mention your budget and when you say "universal" are you wanting DVD-Audio and SACD playback in 2 channel and 5.1 as well?
If you just want to improve CD playback have you considered a DAC to improve your sound quality? Again, your list is of dated equipment and the newer DAC's will outperform the DAC's employed in those machines.
Just food for thought before you spend your money.
