critique my setup -- weak link? best way to improve?

I just put together my first turntable setup after many years of listening to CDs only. It sounds pretty good -- good enough that I'm curious how to make it better. (: What weak link(s) do you see in this system? Where is the best bang for the buck?

Between the two of us we listen to a wide range of styles (symphony, choral, folk, indie, dark wave, metal). The one constraint is that the speakers can't be larger than about 20" tall and need to stand on a wooden sideboard/console type thing.

The setup:

Pro-ject T1 with built in phono stage

Luminous Axiom passive preamp

Rotel RB-1070 power amp

Blue Jeans interconnects

Klipsch KG2.2 speakers

Amazon Basics 12Ga speaker wire, Monoprice banana connectors
