i have a pair of monitor audio r90hd speakers connected to a yamaha rx-n600d network av receiver and an ipod classic but would prefer a clearer sound as my hearing is getting worse due to a longterm illness.i would prefer something smaller than my current amp and the ability to play cds, the arcam solo is out of my price range.heard the marantz but with its own speakers and wasn't that impressed sounded better with tannoys but i already have speakers,the salesman said mine weren't suitable, is he right or trying to get me to buy something i don't want.
