With an OPPO BDP-95, BDP105, or BDP-103, you just feed the analog outputs for 2 or 5 channels direct from the OPPO to any amplifier or receiver; it is a no-brainer.
OPPO also has the best DACs and resulting sound quality of anything you can buy at anywhere near the same price. They just blow away the competition for both sound and video.
If you are watching movies, you also use an HDMI cable to the TV to send the video there.
The Wharfedale Diamond 10.1 and 10.2 speakers are outstanding.
