Any device with a preamp or variable volume control is just that. So no, not a problem. Worst case you can have ground hum. Maybe you got mistaken with 2.5mm or 4.4mm balanced, if you connect that to a balanced amp without any ground potential, you can damage gear because you need a ground for safe operation, E1DA 9038s for example.
9038d however is 100% safe. And in general, "double amping" is a silly term imo. Most outputs nowadays have a line driver or are amped somehow, most output stages are just that. It is much more rare to have an unbuffered, direct DAC output.
