In no particular order:
Nevermore- TGE/ Testament- The Gathering: My favourite work by Andy, and some very *fitting*, huge sounds on both of those albums.
Nile- Annihilation of the Wicked: Fucking brutal! I wasn't a fan untill I hear this album, and I love it based more on the production than the songs, though there are a few jems in there.
Evergrey- In Search of Truth: While the guitar tone on Recreation day was one of the best around, I love the vibe on this album. It was the first which featured Henrik on guitars and Sven on keys, and their addition to the songs was captured extremely well by Andy (LaRoque). The guitars and bass worked very well together, and the keys and vocals were full of awsomeness. Probably my favourite album for the last 5 years.
Honourable mentions:
Nightrage- Sweet vengance
Death- Symbolic
Dark Tranquillity- Damage Done
Kreator- Violent Revolution
