I would agree with Brain that the universal players do a fine job, but in your search for excellent musical playback, a stand alone player would better suit your needs. But don't let my words tell you, let your ears. If you can't hear the difference for the price, don't pay for it. It's as simple as that.
Just a note when testing universal (and standalone) players. Be sure to use the analog outputs vs. the digital to be sure to utilize the players interal DAC vs the receivers, since the players will most likely be better than the one of your receiver. You can test this out for yourself as well, as it is not always true, but most of the time is. People get used to wiring up only a digital cable from the DVD or universal player to their receiver in the world of HT, and discount the players internal DAC's. On higher end transports, you are paying for the upgraded DAC's, so you should use them (if they prove better than those in your receiver), and the analog interconnects will allow you to do just that.
