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.

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.
