Need advice on upgrading amplifier for Paradigm S1

I am listening to a pair of Paradigm S1 V.3 speakers through a Eastern Electric MiniMax Plus DAC and a Pioneer VSX-1019AH receiver. I believe the Pioneer uses ICE amps which do sound nice, but how could I upgrade the amplification to achieve the next level of resolution, dynamics and musicality? I'm on around a $2,000 budget for the upgrade? Also, I do have a Hafler P3000 power amp I am not currently using and have a SOTA Star Sapphire Turntable.
fwiw, i heard the paradigm s1s mated with a naim nait integrated (50w) and it sounded great--all the resolution, dynamics, etc. you seek
