Yep, that was the one I was looking at. The B4-X has a balanced output. Not sure how well that will work from a SE input...I remember @KEV G talking about the ALO Dual Mono but that's out of my price range. I love ALO's stuff. Have also been considering the Rx as well as Headamp's Pico Power (which I had).
I don't know how THIS ONE would work for you with 4.4mm in and out but I've seen some good things about it.
