Hi smoove,
Used to be a what hifi junkey and knew a little bit but may still be off the mark with what i say here!
That's a nice set up you have there and should sound great!
Don't know what sound you expect or are getting. Should be fairly warm and energetic of what i've heard from marantz. Though the size of the monitors could mean that bass isn't overly obvious! There are a couple of things you could consider.
The speakers are fairly small standmounts. If you're not getting full bass or the treble is overzealous, positioning them closer to wall may help. Indeed, the closer a speaker is moved to a corner the more the bass will grow (though this corner approach is frowned upon as it effects stereo imaging).
Once you get your ideal sound you could also try toeing the speakers in. This will improve stereo imaging and make the performance of the music more real!!! You can do this by pointing the speakers towards a converging point about a foot in front of your head when you're sat in your prime listening position!
Leaving the components powered on always helps snooth the presentation of the music too!
Also, you mention the QED banana plugged cables (i take it these are the speaker cables) hopefully you're using similarly capable cables to connect the cd player to the amp. Usually reserve 10% of the total budget for cables. I made the mistake of sticking with some fairly decent but cheap (£50) cables when i upgraded my components to a Cyrus CD7Q, PSX-R and Smartpower. It was initially dissappointing until i took the plunge and bought some cables priced at £150 (Russ Andrews Silver Streak)!!!
The increased price of the cables may seem a lot but when you consider that the CD player and power supply (effectively a combined unit) cost £1500 the £150 cable completely reflected the rule above! Since that purchase i have never looked back!
What stands are you using? Light weight or unfilled stands can starve bass weight and attack! Bluetacking the speakers to the stands can help improve the presentation!
Finally, always a contentious point... but, are the cables you're using directional? If so check that the arows point in the same direction the signal is travelling (e.g: arrows on cable between cd player and amp should point towards the amp - arrows on cable between amp and speakers should point to speakers)!
Hope that helps and apologies in advance if anyone finds that something i've said is completely wrong!!!
