I have done well with sony's stuff. Never a poor product in home audio, home video, cameras, MP3 on anything. I got stuff from them 25 years old and still kicking.
I have a big setup a Sony STR-DH100 stereo amplifier with SSF-5000 floor speakers. I have an A/B speaker switch and have ssb-3000 bookshelf speakers for the other half of the house.
I know someone with the smaller ssb-1000 speaker and he likes them alot. My Chiropractor has a ssb-1000 in each room of the office. The sound is good, but turned up loud being an office and all.
I'd get a 100w amp and just keep it low. When you want something bigger, you got an amp for it. You can always buy some bookshelves and put a touch bigger set on the wall.
