cambridge audio Azur 651A vs NAD C326BEE or NAD 3300 /3400

I am trying to decide on these integrated amps. I like the cambridge but know zero about it.  I have had other NAD peaces. I have a NAD Masters M15 now but I want to go back to stereo not an ht preamp so I am looking at these and the prices for the 326BEE and the 651A are similar.

no place for me to try them out.
