Would a Sony CT150 soundbar be a downgrade?

[PCFan]

I right now have the Yamaha SP1800BL speaker system with a Yamaha RX-V667 AVR. I'm using only the 3 front speakers and the subwoofer for 3.1 sound due to lack of good spots for the surrounds due to my bedroom's shape. I've been thinking about selling my AVR, speakers, and subwoofer and buying the Sony CT150 soundbar. I thnk that it would look better in front of my 32 inch LCD than the 3 satellite speakers on my TV stand and I'd be able to watch from my bed as well because the front L and R speakers block some of the screen when I view my LCD from a small angle or more so I have to be pretty much seated centered to avoid the L and R speakers from blocking some of the screen. Would it be worth it for me to buy the Sony CT150 soundbar or would there be a major downgrade in sound quality?
