I currently have the Yamaha Aventage RX-A2030 receiver powering Polk Audio RTI-A7's towers as fronts, A3's bookshelves as rear surrounds, and the Csi-A6 center channel speaker. The RTI-A9 towers just went on sale for a hot boxing week price so I pulled the trigger on them with a plan to move the A7's to the rear, and the bookshelves as mid-surrounds (my room doesn't really work with this). After thinking this over, and since a considerable amount of my listening is music (often in 2 channel), ...
Could I leave my setup as it is, and use the AVR's front pre-outs to an external amplifier (I'm looking at the Emotiva XPA-2), to power the A9's along side the A7's.
Will the pre-out still output signal when the AVR speaker output channels are being used? And assuming this works, would this be a good idea in regards to any timing differences or speaker interference?
Thanks in advance for any responses.
