I'm no audiophile, that's for sure. I notice that some receivers in the $200-300 range have fairly good reviews and even get "best buy" rating by consumer magazines. I know that the receivers in the next grouping $300-500 probably have better features and reliability plus specs that suggest better performance. I am therfore shocked to find that some people consider $1000-2000 receivers to be "low end". Just what audible differences would a $2000 receiver have over the Sony/Yamaha/Panasonic/JVC $200 receivers?
