Not aimed at you, just in general. Thanks for that link
The advantages of DACTs over POTs are not really of much debate even on HF.
There are people preferring POTs for their ability to set finer volume than a stepped DACT. For me the nfb28's 160 steps is fine enough for volume adjustments.
Top amps like GSX Mk2 offer the DACT volume control as an $200 upgrade over stock POTs. It is really a bargain to have it on nfb28 by default. But I guess there is no way for kingwa to include this on compass 2. Similarly, hifiman uses the stepped attenuation on its flagship hm901, but replaces it with POTs for it's little bro hm802.
