Hmmm, all good food for thought. . .
At this point, the higher cost of the 604's is not an issue. I intend to keep these speakers for a LONG time so the investment now is worth it in the long run. (While I'd love to do the 700 or 800 series, I'd have a hard time justifying buying speakers at that price point. And no matter what fronts I end up getting, I do intend on getting a quality sub, prob a Hsu or SVS.) With that said, it appears things are leaning in favor of the 604's.
-I do listen to music in pure direct mode, at least for now. With a sub that might change from what I read about how the hsu and svs adds so much more to music.
-I was planning on getting the 600 rather than the 60 for the center channel. The reviews I read say it performs better than its smaller sibling.
I was not considering the 603's because I want the larger drivers and from people who have heard both, almost everyone says the 604 sound better. But I believe they were doing a direct speaker to speaker comparison without the use of a sub. . .
Shouldn't the sub blend equally well with the 604's and 602's since they do use the same driver? How important is it that the sub blends seamlessly with the rears since they are mostly used for surround effects?
I just don't want to wonder later if I could've done one better by getting the 604's instead of the 602's. Both speakers have gotten great reviews, hence why I am having such a hard time deciding.
