Thinking of upgrading at arcam faj a22 for used peach tree audio nova 500

Hi, my current setup is the arcam a22 with clear audio concept and Nola boxers.  I want to upgrade my amp first and eventually my speakers.  I have interest in peach tree nova 500 used.  Would this be a major improvement on my system or should I get something else.  It is important to me to have a dedicated phono and ground on the amp. Thanks as always for whatever advice (opinions), you can give me.  Charles
