Not CR series, but I am running a C-70 with a B-3 and I love the sound they produce. Just really smooth and listenable.
I have an ONKYO on the other side of the room as a second system and when you first power it up it has this LOUD boombastic bass heavy sound which a lot of visitors say they prefer to the Yamahas. Spend some time with both though and you quickly realize the YAMAHA set up is so much nicer to listen too.
The bass doesnt overide everything, it is nice and tight and just where it should be.
I am currently using a pair of Diatone speakers with this set up but on Friday will be adding a pair of NS200ma's. Can't wait!!
