Lamm 1.2 mono's versus Aesthetix Atlas mono's

Both of these amps are available on Agon for about the same price ($10,000). I would use them to drive Martin Logan Summits (if it helps check out the rest of my system). I am currently using Rogue M-180 amps. Anyone using either of these amps to drive Martin Logan speakers? Any general opinions about one amp versus the other are welcome. To answer the frequent follow up question of, "what are you trying to achieve?" better sound, you don't know what you don't know until you try. Thank you
