NAD 216 v NAD 2600/2700 Which is better?

As funds are limited I am looking for an NAD amp. I have owned a number but not side by side and that will not be happening .  I do not like the sound of the newer units as much as the older ones.  I will be using a 162 preamp.  For those that have had them or maybe compared them which is the better sounding unit?  The 216 or the 2600/2700?  Power is not an issue for any of them.  I think the 2600/2700 run in class A for the first few watts according to the 1988 lit.  The 2600 sold for $899 and the 216 for $699 but not sure that means anything.  Thanks
