So I currently have a small 5.1 living room setup using the Sierra Luna's as L/R, the Sierra Duo as a center, HTM-200's for surrounds, HSU VTF-15h mk2, and Marantz sr6014. I will be moving within the next few months, and hope to have a larger, dedicated room for home theater, and am trying to reason through where to go with the speaker system. I'm hoping to end up with a 5.2.4 system. (may add more to get to 7.2.4, but that's a future problem.) The new CMT340SE2's excited me as a possible option for a relatively inexpensive option for identical bed-layer speakers, but given that I already have Sierra's for my LCR, I was wondering if this would be side-step or even a downgrade from what I currently have? Looking at the sierra lineup, my first thought would be to get new L/R speakers, and move the Luna's to surround duty, but I'm unsure which speakers would be a good fit. Use case would be around 70% movies/TV, 20% gaming, 10% music.
The tower's are a little out of my price range at the moment, so I guess I'm really only looking at the Sierra Duo vs EXv2 vs LX. The Duo's would give me an identical LCR, and are fairly easy to drive, but how do they compare to the EX and Lx? If I used the EX or LX, would my AVR be enough to drive them or would I need an external amp? Would the LX match well with the Duo center I currently have?
Thoughts?
