"Great review and great site btw, making me want to buy everything! I've been looking for a device like this and your review did enough to suggest this was the right bit of kit. I have to say it's a great little gadget, just probably not worth the price. Few things to mention, firstly the bluetooth connectivity (S5 to E5) isn't as solid as I'd like it to be, on the tube for example it constantly drops out when in a tunnel. The other issue is that there is no software support for Linux. This is a massive shame as I'd pretty much bought this to act as an improved DAC for my laptop. I think it says a lot about the versitilty of the E5 that I'm not that bothered" - Toby Graham
