Arcturus (Masquerade Infernale, Sideshow Symphonies; not super technical though).
Meh, The Sham Mirrors is by far their best.
A good new prog metal album is Arch/Matheos' Sympathetic Resonance. Arch's voice might be a bit of an acquired taste, but if that's not a problem for you, their first release is fantastic, and doesn't descend into pointless wankery like so much other prog metal.
The (now ex-) 2nd guitarist from Cynic also did a little instrumental side project with some other guys, Exivious. Pretty sure they have a Myspace page or whatever where you can hear some of it. Basically it's fusiony metal... great playing, great writing... and most of the guitars were recorded with an Axe-FX.
