Dear team, I continue to love my Luxsin X9. I was wondering if you could consider adding a feature to mimic tube distortion. Either adding some level of even harmonic distortion and offering different possibilities. I do not know if it is doable with the DSP chip or manipulating the harmonic distortion adjustment of the DAC on purpose. I am sure most of the audiophiles would be super interested about this and would take the X9 to new highs. Imagine simulating "tube profiles"... Kind regards
