Looking to get the Marantz 6002 amp and cd player to use with some B+W 685 speakers (yes me again but a slightly different angle to this thread). 1. I currently have a Denon-1930 DVD/SA-CD player. Would using the Marantz cd player give significantly better sound quality than using my Denon, or am i just as well to save my money and stick with the 1930. 2. If it's worth me sticking with the Denon, then is the marantz amp still a good option considering i am saving myself some money and have a little extra to spend on the amp. Thanks in advance for any feedback and advise that can be given.
