Do you think there should be a concern about build and durability? As the 683's are approx. 60lbs while the Tritons are only 32 lbs.
And have you had any experience with the center channels? What's your take for the centers and HT use?
Well I have auditioned Monitor, Paradigm, Klipsch, Focal as well as a few others. Unfortunately, there is not any KEF dealers by me, so I can't audition them. The Triton 7's and 683 S2 still remain the top of my considerations with a budget of ~$2,000 to ~$2,500 CAD. I really like them both, but in different ways. That's why I'm just looking for additional input/experience from others. The 683 + HTM61 is approx $2,200 and the Tritons + Super center XL are approx $2,500.
For subwoofer, I have budgeted about $1,400 and I have been eyeing out the PSA XS30se.
