I was looking at both the primus lines and the northridege lines for my 7.1 setup. I'm now learning toward the northridge line for 2 reasons: first, because I would like to have something larger then a 6 1/2 main, and secondly because I think the cherry finish would got better in the room.... ok that may not be the best reason, but still. When comparing prices of the various Northridge floor standing speakers the I found that the E90 is about $55 more a piece then the E80 and the E100 are about $55 more then the E90. So for the price differences which is the best route to go? Does the extra $55 to go up to the next level justify it? At what point does it become less value added? I could nickel and dime myself to death. Oh and I plan on going with the E10’s for surrounds and EC35 for center. Let me know your thoughts. Thanks.
