I use the following:-

Sources Denon DVD2910/Squeezebox 2 (modded)

Processing 518/568.2MM

Amplifiers 557s

Speakers Shahinian Arcs (Front) Quad 22L (Rear)

System works well for me, I got a good deal on the Denon and it offered DVI-D and HDMI output which isn't available on the 598. Not in an urge to change anything so I must be happy with it!

Interesting I also have a pair of D600's and in analogue mode the 557s/Quad22L's comfortably out perform them, but the D600's with a further Squeezebox make a great second room system!
