The Takamine C132 actually is a great guitar. It is not as loud as modernly built instruments, but I think it has a more beautiful tone than even a lot of luthier guitars I have played. You'll have to look carefully if you want to buy something for $2000 that significantly surpasses it. In your situation I'd suggest that you play a guitar side by side with your Takamine before committing to a purchase.
My question is do you know what particular traits you are looking for in a new guitar? This could help people give more appropriate recommendations.
