I can't help you with the comparison, but can tell you that I run Chang Lightspeed's 9900 amp and 9600 ISO in my HT and LOVE THEM, noise floor dropped to nothing (especially important as I live in a condo, so power sucks!) and the sound truly did tigghten up!
I can't give you positive or negative on audioprism, but can say you won't be disappointed with the Chang stuf...
Hopefully this helps.
