Are there any good (re: great) 5 disk DVD players on the market? I'm looking for something to replace an old 5 disk yahaha cd player that can do a great job with dvd but also an excellent job of cd reproduction. I have seen but not demo'd the Sony 670D and the Harman Kardan DVD 5. Also believe that Yamaha may also be bringing a 5 disk DVD player on the market. Any ideas?
