It will be a good jump, but what headphones do you have?

It will be able to provide 500 mA to each connection. If your hub is unpowered (powered only by its input USB connection), which one is it (manufacturer and model)? We may be able to discover whether it can distribute that 500 mA unevenly, allowing you to have a 100 mA connection in addition to the 250 mA for the µDAC. But that would be the maximum, one connection in addition to the µDAC. See this Wikipedia article. Of course, the only way to know for sure with your particular USB hub and computer is to try it. |

With HD650 you have to crank it up a bit higher (2 or 3 o'clock) but still gets loud enough without distortion. Do note that I'm not one of those people that require concert-level loudness for all my listen or anything, though. |
