Amp's that are better sounding than a nad 3020

Each amp has it’s " qualities ", attracting various listeners. What speakers are you listening through ? What is / are your sources ? What music do you listen to / enjoy ? How loud do / would you listen ? Do you listen at a distance, or nearfield ? BTW, I am assuming you are talking about the original 3020, or the later 3020a. Have you ever heard a completely rebuilt and upgraded 3020 ?, as the circuits were brilliant for that time.

?

have two sets of bookshelf speakers 

one is 4 ohms 90 dBSL AND OTHER 

6 ohms at 87dBSPL for a 2,83v input at one meter

May I suggest you look for a second-hand Sansui.  Sometimes they come up at close to your budget.  Some Sansuis are excellent and none of them are bad.  They are gutsy and can usually drive low impedance speakers very well due to their generous power supply design.

No idea what your amp sounds like but I am relegated to older stuff due to my budget. I recent scored a Denon PMA520 and tuner for about $150. One of the most pleasant surprises in a long time. Fairly detailed for its age (1990 or so) and sounds great with KEF Q150, Pioneer FS52, or QAcoustics 3020i. This is the amp that put the Sansuis and Luxmans back in the closet and started me down a spending spree of old Denon integrateds.
