I do a lot of inhouse mastering for my projects (mostly music for TV) but some local album work too. my mastering chain is mostly waves (mastering suite) and Ozone for some stereo widening and exciter, which i think its really best at.. I've tried the t-racks demo but it just didnt work for me, it just seemed a bit harsh and obvious.. for the warming up effect, i like vintage warmer better. I know waves is in a different price bracket, so if i had to do without, i'd probbly use vintage warmer AND Ozone. Ozone is a a PITA to control, but just go subtle with the parameters and you can get some really nice results.
Ofcourse, its all up to your ears and what you like, and if its t-racks, then just go with it
good luck
