I only listen to Jazz at the Pawnshop in stereo. Cafe Blue is only stereo.
I had the 83SE for years so I knew what it sounded like. I had a Denon 2900 before that and the 83SE was an improvement over it. Those are considered benchmark units, then the 105 came out and became the "standard" for players at the time. I would say it is more like a fine wine, where it is subtle what makes it better, but you CAN taste it. Is it worth
the price may be a different story (and I don't like expensive wine lol) and everyone's tolerance is different for how much improvement you get. It isn't like "a veil was removed" and this isn't like cables or other things that people assign magic words to, it is verifiable as noted in Gene's bench tests of the 203 and 205. The difference between the 105 and 205 is hard to hear, but between the 83SE and 105 I could hear it.
We reviewed Oppo's newest Blu-ray players, the UDP-203 and UDP-205. With very responsive interfaces and state of the art playback performance The UDP-203/205 will leave you wanting very little.
