Upgrade from Technics SP25

I currently have a Technics SP25 with ATP-12T arm and Denon DL-103 and a solid, custom plinth. I think this combination punches above its weight class due to really good synergy between arm and cart. It has big tone and tracks really well. However, I am looking for an upgrade that digs a little deeper and extracts more detail.  I was going to purchase a Hana EL cartridge and give that a try. However, now I have a larger budget ($2500) allocated to this upgrade and am trying to determine best course of action: eg, buy an entirely new turntable, upgrade arm and cartridge, stick with just the cartridge upgrade,etc. Any advice is much appreciated. Also, I am currently using the phono stage in my Crayon integrated amp. After experimenting with different phonostages the one in the Crayon just sounded the best .
