Some manufacturers, with their higher-end receivers, have gone from six-channel high-rez analog audio input to eight-channel. Are there any high-rez multichannel disc players, or any other similar audio sources for that matter, which will output an eight-channel signal? Obviously, you have seven-channel amps, leading to eight-channel pre-out sets (the seven channels plus the LFE channel). But that's only amplification and pre-amp level output. How would a disc player generate eight channels of input versus the current standard six?
