Looking for amp reccomendation

I currently have an NAD Home Theater 7 channel amp with Persona B Speakers as main. I would like to purchase a used Class A or A/B solid state amp for around 3K, used give or take a few dollars for two channel listening.


Do you think I would really notice the difference in sound when listening to two channel stereo with a class A amp versus two channel set up on my Home Theater?

Suggestions for amps? Thanks in advance.  Sorry about spelling recommendation.  Couldn't edit.
