I assume that you use transistor amps because -120dB is between 1000 and 10 000 times lower than your typical valve amp distortion (0.1-1%).
If THD is that much higher there is no chance that anyone could possibly hear anything at -120dB as it would get completely drowned out by the distortions.
I suppose 0.0001% THD could be achieved by a SS amp if it uses vast amounts of negative feedback.
