Not sure the SVT3 is the problem Mr F to be honest.
I just re valved it and had the bias set and the amp sounds sweet. I've used that set up at rehearsal albeit in a smaller room and it sounds good. On that stage and in that venue it didn't come together.

That's the sort of place where you need effective EQ, especially with a cab with lots of bandwidth, partly the problems with choice of hifi cab, because they brutally show the limitations of other stuff, like the room, but the control is ultimately down to the amp.
Also, isn't the SVT3pro solid state? Don't usually have bias set in them (although they do need it, you don't change out the power valves and replacing transistors tend to be like for like).
