Or X3 + iBasso DB2 + PB2 = fully-balanced rig for less than the price of the DX100!
I'm convinced that one of the reasons why the balanced iBasso components never really caught on was the lack of suitable DAPs with digital output. Not everyone wants to run their gear off a laptop when on the move, and the global supply of old iRivers is drying up......
Just a thought.....
x3 = 180usd + shipping
db2 = 300usd + shipping
pb2 = 325usd + shipping
dx100 = 830 + shipping
assuming there is no shipping cost involved, i'd still go paying 25usd more for an all-in-one device that sounds probably better and with a smaller form compared to a 3-layer brick, and it doesnt need at least 2 interconnects connected to each other =)
