That's the stuff, though I prefer the newer Mannaz and Freyr to Imperious and Andromeda.
Most notable difference between them being that Mannaz and Freyr combine to give each of the standing stones unique effects for each race (ex, right now I'm playing an Imperial support caster and doing most damage through a follower, so I'm running with the Atronach stone - which, for Imperials, makes healing spell 20% better).
The "Vanilla+" / minimalist mods from Enai are also pretty solid, consisting mostly of streamlining and polish rather than Ordinator's "Smiths can take perks to craft a dwarven gun turret".
