I recently purchased a Yamaha RX-V1400 to replace a Kenwood HTIB. I decided to go with the JBL E90's for my mains and now want to replace the Kenwood surrounds. The 1400 is capable of 7.1, so I am looking at either two pairs of the E10's or N24 II's. I can get the N24's for $75/pair and the E10's for $135/pair. Any suggestion on getting one over the other?
