Hi Ken, though I do not own a pair of Vanatoo, I did have the pleasure of hearing them at Axpona a couple years ago. They were great sounding even after listening to the best equipment in the world. Everyone in the room was shocked by their level of performance. I can't see how you could go wrong with an all in one and a 30 day return policy. I would also recommend a W4S Recovery along with a decent quality usb cable if you want further improvement. I use Curious usb which are pretty pricy but I have heard good things about a inexpensive Belkin Gold usb.
