Anyone ever try one of these with their setup? http://www.fiio.com.cn/products/inde...nuID=105026001 Not sure if it would handle the input of a bass guitar or a preamp (don't know the input impedance of the Fiio), but really light and compact. Its the the size of an iPod shuffle. I read some good reviews on it when using it with a smartphone, iPod, etc. Obviously you would have to get a cable to interface as well since it's a 1/8th input connection. Looks pretty cool if it would work. I figure someone here must have tried it once?
