Pedrillo, in the context of what you're trying to achieve (assuming budget around $4K to $6K), you should put the Lector CDP-7T on your audition list, especially if you're starting to love operas. This CD player is about music, not hi-fi. It's excellent with voices.
Do a search on Lector. There's a group of members who swear by it.
