Are you looking to buy one that just "makes it" and avoid one that just "falls short"? For the most part it is marketing speak, since most equipment performs pretty well today, or better said, you don't need to spend a lot of money to have "high-end" sound. I suspect folks would think that $500-$750 integrated from companies like NAD, Rotel, Cambridge...are truly high-end, but they sure do capture an awfully large % of what is possible from 60-100 watts SS amps.
