iFi Go Blu review : Whathifi.com: 5 stars, Highly Recommended
iFi Go Blu specs:
More power than dongles, enough to drive many full sized headphones, very low drain on the batteries of the source device since the power draw is only on the BT antenna, great wireless connectivity, but also option to connect with wires if you want, extras like xbass and xspace, smart and convenient form factor, literally the size of a small match box. One of my best audio gear buys in recent memory.
An ideal product, Especially for balanced headphones. It drives both my open and closed back headphones with ease. My single ended headphones also sound great. Pairing is immediate, and I rarely experience a loss of signal. The quality of the product is far and beyond, what i expected for this price. The staff at the Headphone Bar, are always accessible , if you have any questions. Thanks for another great product.
