I like the recommendation above about saving up. However, if you’re looking to liven up the sound (note that it might not necessarily tighten up the bass) you can get close to $1K on my Dali Zensors 7s. I have to say these are fun.
Would also look at Monitor SE 6000F for $1K, but I tend to like a bigger sound. The bass will be tighter here but not as full at your T1s.
