I’ve been on the fence to upgrade from my current KEF Q100 bed layer set up for a while. I just added 4 SVS elevations for heights and I’m ready to solidify an upgrade choice for LCR. This is in my main living room.

I could go CMT340s now, but I went down the rabbit hole of potential off axis issues with that MTM center design. I want great off axis, so that leaves either the Sierra 2EX or the LX. Both of those I would need to save more $ and it would take me longer to obtain.

Primary purpose is movies and video games. Where do I get the best long term enjoyment for the money? What are the key differences between the 2EX and the LX? Could the KEF Q100s still perform as surrounds or should I upgrade them down the line to an Ascend speaker? If so, which one?

Thank you in advance and I look forward to hearing some ascends for the first time.
