I've EXTENSIVE experience with HANDS ON time with both these amps and the speakers.
First, the X150 is a better amp than the DNA1 delux. It's possibly 75-100% better overal(run from it's balance inputs!..not the RCA's). Then again it's twice the money over the stock DNA1. If you don't have balance outputs from your preamp, then I would suggest trying the DNA1. But if you have balance out's from preamp, and the X150 is in the budget, then I think you should be pleased. If it's a stretch, then the DNA 1 is fine for now, and it's a step in the right dirrection.
OVerall, there's no other solid state amp I can think of that's better for the money than the X150 for most practical purposes.
good luck
