I had a 2012 anthem x2 26″ wheels 100m fox front forks and rear shock.
Like the above comments, they are absolute rocket ships, climb like mountain goats aswell, perfect tool for big xc and trail centres.
I got rid of mine after a day of off piste in the forest of Dean where it felt quickly out of its depth, mainly due to the head angle on the near vertical downhills.
Replaced it with a trance and have had trance and reigns ever since (currently have a 2017 trance 1, 2019 trance advanced 1 and a 2015 reign 2 all 27.5) and the difference is night and day.
Trance is so much more capable on the downs and perfectly at home riding xc and trail centres.
Doesn’t climb aswell as an anthem but not much does and still pretty damn good, well compared to my reign, that thing is a handful on steep tech xc climbs! But an absolute missile down
