Anyone tried one of these? It's about the size of a USB thumb drive and is a DAC (Sabre 9023) and headphone amp. I wonder how good something this size can be. It's $250 so not a huge investment as something to try out.
I'm thinking of picking one up to use at work and on the go, supposed to work with my Mac machines and my Windows machine at work as well. I'm curious if anyone has picked one up, has any thoughts on it.
