DISCLAIMER: Burson sent the fun to me for a honest review. I'm by no means a expert reviewer this is just my opinion of this amp. All done with my ears and moddest gear. SETUP: PC(spotify premium)>usb>Audio-gd NFB 28.38 fixed out>Fun input>HD-600 and Hifiman HE-400i PACKAGING: The Burson Fun comes will packaged. In the box you will find the Fun encased in tight fitting foam. You will also find two boxes on each side of the fun. One contains power brick the other a nice set of RCA's,fuse,adaptor and allen wrench. BUILD: I thought the Fun was well...
