Hi,
 
Is it wise to go from a mobile dac/amp headphone out socket into a full size amp?
My Dac is a Oppo HA2 which does not have enough power to drive my HP's.
I was unsure if amped out (headphone out) to input would cause damage over time?
The HA 2 does have a Lineout but does not carry as much bass boost which is the reason
for going Headphone out.
 
Thanks

I would just use the line out because otherwise you would be double amping.

Yer that is what I thought. But I was not sure if it was "safe. Does double amping cause issues or is it more to do with the distortion in the music?
 
When I Line out... the bass boost is missing from it.

It's safe, just make sure the gain on the first amp is not too high as to clip the input of the second amp. If you have excessively high voltage going into the input of the amp, that could conceivably cause some damage. According to the specs, the HA2 can output up to 3V (30mW into 300Ohm = 3V), which I doubt could damage anything. Line level is typically 2V, so you can just use the low gain setting or reduce the volume a bit and you should be good.
