Hi everyone. Has anyone tried the NX4? I haven't seen any threads or reviews here. There isn't much information about it elsewhere either so I guess it's pretty new. Link Stats on eBay I've been considering getting it for my DT 770 80 Ohm but I don't know much about DAC/AMPs, any idea if it is likely to be a good match? I've also been considering other stuff like the FiiO Q1 and Topping NX2, any suggestions appreciated.
