Don't know if this is even possible but how would one even know if a company put a new receiver in the market that actually made audio quality (for DVDs, Cds & TV) so much better that there would be a night & day difference in sound quality from existing systems? Is that even possible or have we reached the point of diminishing returns? If there was such a receiver, how many of you would jump to buy it even if you were happy with your receiver?
