If you are worried about midbass and a slightly rolled off top end then I'm not sure Marantz (assuming the 14S1 and 8005 have the same house sound) is the right answer.
It was those very qualities that prevented me from buying the Marantz. I'm running KEF104.2 (tweeters restored) with a Modwright integrated.
Many others would disagree so I recommend trying a Marantz (or any other player for that matter) in your system first to ensure a satisfactory match.
