Just finished reading it. I think you did a great job going through all the major bullet points and comparing them. I have never heard the 8.A but it's clear that you did a good job because I feel like I can understand it's sound signature just knowing the AS-2's signature, which you seemed to hit dead on besides the fact that I do not have that bass valve you have...(fine, so I'm a bit jealous, just means money will be spent by me in the future to get it one day)
Thanks, that was exactly my goal, so I'm glad it was clear. I'll be able to polish a few things tomorrow, but I hope it helps.
