Are the (free) Spectre Sound IRs any good?

So, I took one of the Fremen presets that I picked up a while back (5150) and dropped in a couple of the Spectre Studios free IRs that Glenn created to see how they sound.... pretty dang killer sounding IMO, but hey, let me know what you think.... If you like what you hear, be sure to go to Glenn's website (Spectre Digital) and pick up those IRs.
