How good are the AES Sixpacs???

After spending the day chasing around my toddlers my brain was mush so that's the reason I'll give for a poorly worded previous post.

I realize no one can assess how these amps would sound in my system. I was hoping to get impressions from owners of how well they like them? How is their build quality? What did they do for their system and any other advise they may have for someone thinking of buying these amps.

Thanks
