Chris, some publications(e.g. Home theater, Sound&Vision, Audioholics)do lab tests on receivers rather than simply supplying a bunch of sometimes implausible subjective impressions in their "review". I'll link just the latest lab results on your
575 , which illustrate the superb performance that we can enjoy these days from even modestly-priced(yes, you could have paid around $250)receivers.
By far the most valuable recommendation that I can make is to explore the world of great classical music that's waiting for you out there.
