Well I bought a 3300 in 2001 for $1700 This may be a little older and looking at the denon site briefly in archive I saw 5700 5800 no 5600 but if it is that series Its powerful but limited and when I bought mine the 5000s were to pricy for me. But if I had 300 bucks and needed a good shop stereo that would do nice. unless I'm totally wrong.
