Sadly no.
I hope in the future versions they give it a higher maximum output power rating (it's enough to get my SZ2000's to rattle, which is an awesome sign, but I want MORE!!!!) and give it a gain switch.
Sorry the pic isn't the best... but it's in use and I didn't want to unplug the cables...
Leftmost is input, middle is normal headphone out, right is 75 ohm headphone out.
You can kind of use the normal vs 75 ohm out as a sort of gain selector - 75 ohm output will be more like a "low gain" sound.
My red charge LED is a bit crooked because I was rushing a bit much last time I took my bMac apart to take gut shots, so I gotta re-straighten out that LED i bent a little bit.
