Massdrop x THX AAA 789 Amplifier - Official Thread



Bummed that I hesitated and missed this one.


So been listening to this more today… and with the Focal Clears it sounds wonderful balanced. Threw on my HD800(SDR) and was not pleased synergy was not good for me.

I went back to listening with my Bottlehead Crack and Cayin HA-1A MKII, with my HD800 … Much better!

I do like the THX 789 with the Focal lineup though, it has good synergy there, at least for me.


The 789 is unforgiving of any high range harshness or other issues. But it’s becoming “normal” to me over time.
