Squarewave measurements are common in tests, this is done for every Stereophile amp measurement for instance.
I get what you are saying, and since the room is an unknown factor I always recommend home trials (meaning being able to return the product for free or just return shipping, no $50 restocking fee or any of that nonsense).
There are more to DAC measurements than just a flat frequency response. There is THD, IMD, noise floor, volume linearity (if it has volume controls), channel mismatch, channel crosstalk, etc.
That is because the slew is so fast, that it is not letting the amp continue to translate the DAC square step waveforms into true analog waveforms
