bose good if all your listen to is classical music, otherwise, forget it, movies, pop/rock, esp jazz sucks ass for bose, i know, i have a set of 901's set of newer 701's, and a set of acoustimass. They are are currently sitting unused, either unplugged, or B set. They were good, say 10-15 years ago, not anymore.
Harmon Karmon is good, HK, but they also are jbl, infinity, mark levinson, and a bunch of other name brands, same company, same stuff with some exceptions. Only way is to listen to them yourself... Just stay away from all those new ceramic or metallic woofers, they sound like shit imo.
Honestly, i do not think you could go wrong with most of the midline HK stuff, meaning upper end jbl, infinity speakers. For the price, they are a great value. audioreview is a very good site, i agree with the avg. review as long as there is a large number. You can tell when some things are POS if lots of people say they are... alot of companies are good, but are you willing to dole out the cash, i'd rather spend it on mods.
But you still have to have a decent entertainment system, so my current speaks are all infinity(rs5,rs3,cc3 center,bu15 sub) for main system with sony-935 rec, all for less than $1500 shipped to my door. Love the speakers, unbelievable for dvds which is about all i use them for these days anyway ever since mp3's...
