My current speaker setup is a bit of a shameful hodge-podge, so I've been starting to consider a speaker upgrade. I'm a speaker novice, never having researched or followed the speaker forum. Aside from avoiding Bose, I really don't even know what brands are good and what are not. Cost is an issue -- I don't know how little I can get by with spending and still make a worthwhile upgrade to my speaker system. Perhaps I can recycle my sub & center and just replace the other 4? Here is my non-speaker equipment: Receiver: Sony STR-DE835 (5.1 DD/DTS) DVD: Panasonic RP62 TV: Toshiba 50H81 Here are my present speakers: Center: Klipsch SC1 Sub: Yamaha YST-5W90 Front L/R: Bose 501 Rear L/R: Bose 301 Room size: 9' wide, 21' deep, 6.5' high Yes, I'm well aware Bose has a dreadful reputation among those who know about speakers, but I picked up all 4 several years ago for a total of $75. What would you all recommend?
