Also looking at an svt 4 pro for its all valvey goodness but the website has a few power ratings for it which I don't fully understand, can anyone shed some light on what it all means?!

There are two power amps, each delivering 300W into 8 ohms, or 490W into 4 ohm. You can use the 'bridged' output to give 900W into 8 ohms or 1200W into 4 ohms,
