I am planning to purchase the B&W DM 603S3 however was also intrigued by the new B&W CM 7. Need recommendation on which one is better to be driven by the below amplifiers!!

The amplifier that I use currently is an age old Onkyo Integra A809 Integrated Amplifier however I am also planning to upgrade to either

B&K 125.2S2 for power and B&K Ref 5 for pre-amp

OR

NAD C272 for power and NAD C162 for pre-amp

Any recommendations will be appreciated

Thanks

Tim
