Recommend upgrade for NAD C541

Thanks for the advice so far...

First of all, the power cords are fixed on the C541 and the C370.

Second...I am open to a amp upgrade, if that is certainly the weakest link. Actually, I am open to upgrading any component (CDP, Amp, Speakers).

But in the spirit of not jumping on the never-ending upgrade wagon, how would you prioritize upgrades and could anyone recommend specific units for each (CDP, Amp, Speakers). I think I'd like to tackle them one at a time and spread them out (say, over a year...)

For example: CDP, Amp, then Speakers - 1) Arcam CD72, 2) Arcam A75, 3) B&W CDM1NT.

Thanks.

I was reading What Hi-Fi? the other day, and saw that they recommended this Rotel combination with the B&W DM602S3s. Has anybody tried this combination?

Also, in listening to my system in the last couple of weeks, I've also been somewhat disappointed with the soundstage for my speakers, which seems very small. The sound is just not filling the room as much as I'd like...which leads me to considering speakers like the CDM1NT or Nautilus 805. But perhaps its the placement. Can anyone recommend a website on speaker placement? I'd draw a diagram of my room and ask for suggestions, but I'm not sure how I could attach it to my response...

Thanks.

I am also considering the 541i or C270 upgrade, thanks. Although from most posts I've seen, bi-amping doesn't seem like a popular combination...would an amp of equivalent price to a bi-amped config be more effective?

Thanks.

Sorry...I just noticed the Rotel combination didn't come out from the subject...it was the RA-02 Integrated with the RCD-02 CDP.

I think I have optimized my room layout...but the bed is killing the highs (in addition to the carpet).

Any comments would be greatly appreciated, thanks.
