Thanks, Sam! I didn't expect to actually find anyone who had heard both models.
Yeah, I can listen to them before I buy and I still might, but it's through Craigslist, and I don't want to jerk the guy around by listening unless I seriously think I want to buy it. It's a good price and all, but I really don't want to go through the hassle of buying new speakers and selling my (VERY HEAVY) speakers unless I'm going to get a significant improvement. Besides, I'm better off still saving for an upgraded cd player like I am.
I will get a sub eventually, that's after the cd player and a couple of power cords. I'll either get a sub or upgrade my speakers. My home office/ music room is so small that honestly I'm not sure where the sub could go! And then there's the wife factor. If I get a sub, she just might kill me. ;)
