SONY TA-N9000ES

I have a Sony receiver STR-DG1000 and the Sony amplifier TA-N9000ES. I read here:
http://www.audioreview.com/cat/amplification/amplifiers/sony/ta-n9000es/PRD_116164_1583crx.aspx

that the amplifier will provide great sound either at 5-channels or 2 BTL.
After I made the connections following the manual instructions the sound level and sound quality are exactly the same as before without the TA-N9000ES. I switched to BTL mode and I've got the same quality. I am using B&W Series 600 speakers.
Am I doing something wrong? Is the amplifier made like that? My receiver doesn't need that amplifier? Is the amplifier broken even when I get sound from the 5 channels? Any advise, opinion will be appreciated.
Thank you.

What differences were you expecting? I doubt there would be any major ones as long as the amp is operating properly.

I'm with Kal - why big differences? The extra power you get in BTL mode may be overkill for your small monitors - you may be already pushing the limits of what you can eek out from them. Speakers compress when driven really hard and will start to sound dull - up to a point adding power is helpful especially in the bass response (but if you use a powered sub then you may not notice this) and then it quickly becomes diminishing returns on small monitors.

Can I bi-amp the 5 B&W speakers using the N9000ES & the DG1000?
Thank You!

Possibly but (1) you will have to figure out some way to balance the two amps and (2) there's little gain (!) in doing so.
