Unfortunately I have not tried the Athene or the Creon but have good experience with the Amphion which I had the chance to demo at home for a week. Not sure if it's any help but here's my two cents.
They are detailed and transparent, and imaging is very precise and focused. On the downside, I found them a little lacking in body, cold, and metallic sounding. I would certainly agree with the opinion about them being analytical and somewhat cold. Not sure whether that's due to the metal tweeter and metal woofer.
Anyway, I didn't keep them and now have Nautilus 805 instead. In my opinion, there are better speakers to be had for the price.
