I've heard several people talking about running straight out of the output of dac and thought they were crazy and still do even though I haven't tried it myself. I'm sure it is ok for most headphones as a lot of preamps have headphone outs on them. I guess it just has to do with the analog output section of the dac. I guess you could also control volume with the computer if that is your source. I just don't think the output section of the dac was meant to work that way I could and have been wrong before though.
Yeah, not a good idea, in general. A DAC output is meant to drive a high impedance input. Depending on the design of the output stage, connecting to a low impedance (virtually ANY headphone) may result in letting out the magic smoke. Very hard to put back in, once released...
