I've tried two scenarios.

I connected the front pre-outs of the receiver to my NAD stereo amp,
and then the speakers connected to that. The cd player is connected
through the receiver. Sounds great - exactly like it does when playing
directly into the stereo amp itself (to my ears anyway).

I also tried the bi-amping option. The nad driving the HF crossovers
and the Receiver driving the LF crossovers. I did this via an input on
the NAD so I could tweak the volume of the HF level, as it has 60
watts per channel as opposed to the receiver's 85 watts. I was very
impressed actually - sounds good - but I haven't really listened to
enough to decide which is best yet.

I've only just got round to setting it all up tonight, so I'm going to
spend some time listening to both arrangements and decide which I
prefere.

Either way, all I will have to do is leave the stereo amp on the
correct volume and forget about it as I have bought one of those
'ONECLICK' multiplugs. So everytime I switch on my receiver or take it
out of standby, the Stereo amp will fire up at the same time without
even having to think about it

I will spend a while with both setups and let you know which one I
decide to stick with.......
