In the low-cost / high-impact category, even though it wasn't on topic - take a look at the room. I've done some minimal, visually non-intrusive treatment that tamed some high-end harshness and really opened up the music.
Congrats on the amp and the improvement - now take a quick look at the room to really bring out the last bit of detail and control your amp/speaker is capable of.
