Currently running a Marantz 4300 Surround Amp with a Toshiba 260 DVD and a B&W 600 S2 surround sound speakers, Velodyne 10R Sub, QED Original Cable.     In terms of improvements of sound quality/performance would I see a sizeable difference in both Multichannel and stereo with the upgrade to the Sony 1200ES, or do I need to dig deeper into my pocket?    Cheers.
