I recently demo'd the B&W 9NT at my dealer, along with the matching centre and surrounds that i already own. And, the detail and clarity was superb on Gladiator DTS, i found myself noticing sounds and noises, which i didn't even know where there!! On the last scene, and russell crowe, is dying, when he puts his hands upon the doors to open them, leading to the fields....those doors actually creak and groan when opening!! I demo'd the 9NT's with a Onkyo amp and Pioneer 737 DVD. Question is....although the speakers were good, somehow i don't think replacing the Spendors with these B & W will have the same effect on my system. I feel the Sony 930 is fast becoming the weakest link in my system. So the question is: Would adding a dedicated power amp to the pre-outs of the sony amp, add some much needed detail and clarity?? And leaving the sony just on decoding and processing duties? A 3000 bonus will be funding the solution.
