I am done with keeping things incase. £50 to your door.
This is a very cool onboard headphone preamp which also has a mini jack stereo in so that you can play with no outboard to your heart's content. When I saw it I KNEW I had to have one. But the bass it was going into will not accomoddate it and I am in a clearing phase to it is available.
Did not know you needed you did, but fancy it you do.
