First, before you spend a ton of money, try a sony 595. I know, it goes for about $99 in the used market. Let your ears be the judge. A few years back I purchased two of these from Sony as refurb's. I was looking for a back up to my Sony 777ES. These inexpensive units, while not equaling the 777, have great sound. A Sony engineer told me the 595 have all the chips that went into the 777. Don't know if that is true. There are reviews of this unit on line. Buy one. Let your ears be the judge.
