Since you are looking at speakers that cost in the 2500 range (the Triton 3+), you should probably put down the best selling speaker in all of audio, the Vandersteen 2's (latest version is very special). Set up with the gear you have, you will have a very neutral sounding speaker, that can throw a large 3D presentation.
What music do you like and how loud? Room size? Those are also important to know. P
