I'd trust Blue Bear's ears (probably more than my own), and if you're comparing the HD24 to say the old Tascam 38 I used to record on, or the old Black Face ADATs that I did my first "real" album on, it's gonna blow 'em away.
But when I was making he choice, I figured once I talked myself into $1500 another $500 really wasn't that much. Plus being able to record at 96/24 straight from my preamp then Fireport into my DAW was worth it.
