<font color='#000000'>Hello. I am about to do the same thing. I currently have a Yamaha RX-V1300 A/V receiver which I purchased about a month ago. Sound is fantastic from this receiver. I have used Harmon Kardon, Onkyo, and Integra products in the past and found the Yamaha to be the best sound for me.
I also purchased some used Paradigm Reference Studio 40 v2 speakers about two weeks ago. I bi-wired them to get better sound. It opened up the soundstage a bit.
I am eagerly awaiting the arrival of my NAD C270 power amp that I ordered. I will use the NAD to drive my bi-wired Paradigms for two channel stereo using the pre-outs on my Yamaha receiver. I hope this combination will give me the best two channel stereo sound and also allow me to have a Home theater setup which is outstanding also. Further down the road I may try to bi-amp the Paradigms using the receiver amp for the Paradigm lows and the NAD for the highs. This would be a little aggresive though (I just hate the thought of not using the amps on the receiver for the mains at all).
The NAD C270 has a variable input gain so I am hoping I can match the sound from this amp with the Yammie's for Home theater use.
I'll keep you posted on how it sounds.
