I just played through the TVX series cabs at a gig recently. They sounded great, although the head was a GK.
I have a Tour 450 that I love. Good, solid, reliable, and pretty warm sounding. Most amps have a "suck" knob, but I really like the "contour" knob. It also has a beast of an EQ. Very sensitive and complex.
I play the Tour 450 through Hartke cabs. I like the way it sounds, and it gives me a nice stable platform to experiment on. IMHO, you can't go wrong with Peavey or Hartke. Both have great products and awesome customer service.
