I'm quite sure its under $500. Check with Oade to see if they offers their opamp upgrade for this unit which is reported to bring out a better redbook presentation. Doesn't do DVD audio but everything else and being an "ES" version it does come with a decent warranty. Not the only choice in the marketplace but a definite contender within your budget...
