Hi Randall, I'd say "other?"!
If your priority is clarity, dynamics and impact for movies and music, these guys are pound-for-pound the champions in my book and would make an outstanding LCR combo I reckon:
These are high performance monitors that would slay any of the speakers mentioned in this thread so far and embarrass many higher priced offerings from more mainstream speaker brands. Their combination of genuine
high sensitivity, high power handling and 8Ω impedance means that your Denon 3313 will have no problems driving these to clean, very loud (115dB+) SPL's. Note that because they are a physically and acoustically concentric coaxial, if required you can simply lay one speaker on its side for the centre channel.
The only downside is that their aesthetics aren't for everyone and this might be an issue in a living room situation. However, each JTR speaker is made to order and Jeff offers a range of custom veneer options
Edit: The Single 8HT's were amongst some very good company at the NE Spring Speaker Shootout
. You might be interested in the attendees impressions of how they performed on the day.
For surrounds, I've often seen the JBL 8320
recommended as a budget, high performing match JTR front ends. They can be found for under $500/pair shipped
WARNING: Your subwoofage will need upgrading if you wish to push towards the ultimate SPL capability of the JTR's!
