VAC is in a completely different league than Primaluna. PL makes good entry to mid level tube gear, where VAC approaches state of the art. Also, the build quality is better and they really stand behind their products. If you have a problem after the warranty runs out, they usually fix it for free anyway.
If you don't want to buy an older model, I'm sure you can find something just as good, if not better, in they're current lineup.
