Hi,
I did a home demo of the NAD C 370 and the C320BEE at home recently.The speakers are wharfedale diamond 8.4 floorstanders.Musically both sound almost identical but with my speakers, the 320bee sounded slightly more involving.But the behaviour of the amps at higher volumes had me stumped.I can rotate the volume control of the c 370 to its entire limit and still it does not sound distorted.But the c 320 bee reaches its max undistorted sound at around 2 o' clock position .I could discern something like a 25 percent power increase in the c 370.I expected more.The 320 bee is rated at 50 watts amd the c 370 at 120 watts.

What is the trip here?Is the additional price of the c 370 justified?
