i can only speak for the 508.24, which was awesoime while i had it. i sold it for the $$$ but now have regrets for doing so. it's a very musical player yet has great detail nonetheless. the bass response rocks too.
as for the others, i have heard great things about the 306 and notso great things about the 777es and muse. go for the meridian or cary.
