    1kHz @ 0dBFS, is it enough?

    The Topping D90SE shows issues when measured 1kHz @ -63dBFS but not @ 0dBFS. Wouldn't it make sense to expand the DAC measurements suite, and perform measurements of e.g. 1kHz, 10kHz and 20kHz at both -3dBFS and -63dBFS? And shouldn't the frequency range in intermodulation plots be expanded to...
