Dan, I still prefer Output Transformer-less Single Ended for headphone listening as that creates some serious magic from my previous experience but this one does allow for quite a variety of different impedance headphones to be used with it. Depending on the quality of the transformer, it may not take much away from the sonic beauty though. So I would be curious to hear it.
