There are some cheap unbalanced switch boxes that could add additional cross-talk. I have a bunch which I’ve replaced with pricier balanced switches. The level may be so low as to not really matter in the real world.

Using a RCA y splitter will mean each headphone amplifier only get half the voltage.

You can use a splitter with no issues, however depending what the input circuitry of the headphone amp looks like, you may need to have both headphone amps powered on to avoid issues from an unpowered input stage. So long as the DAC has a low output impedance, which most do.

Actually, you only have one source (DAC) running so this probably won’t be likely an issue? I remember when I had two or more DAC sources playing and split to a single amp, the sound of the physically bypassed device via cheap switch could still barely be heard as the non-bypassed DAC is muted.
