Recommned me some technical death metal

these ones may not wholly fit your description, but still i'd recommend them:

Necrophagist
Behemoth
Agressor
Esqarial
Trauma
 
this is pretty much the technical death metal thread anyway....

Atrocity (ger) first two albums
Nocturnus
Pestilence (later material)
Demilich
Lykathea Aflame
