Received my THX 789 yesterday from the second-wave Drop. Four months of waiting had me extremely hyped up.
First impressions: The unit is quite a bit larger than my Aune x7s. It also doesn't feel as solidly built as I was expecting, but it's not cheap feeling either. I'm not a fan of the power and input buttons, they feel cheap and unsatisfying. The gain switch and volume knob however are pleasant. Listening primarily with my Auteurs for impressions, I have the volume knob between 10-2 on II Gain to achieve optimal listening levels. I was not immediately blown away by the sound of the 789. Only on two songs so far have I felt like it was very impressive, otherwise it is comparable to the x7s. The most noticeable difference is the increased dynamics of the 789 over the x7s. It is also more precise and has less distortion. The 789 is definitely faster and more exact, delivering more slam as well. The background is pleasantly black, and you can hear (or not hear) the space between each sound or instrument. The 789 delivers you the music smoothly and easily, without adding any unwanted nuances. In electronic music some of the higher frequency sounds come through very sharp, piercingly clear. There is definitely treble sparkle on this thing. Some electronic music/sounds can be less enjoyable because it is so revealing and the decay is so fast. This could also just be the Mimby. Natural instruments sound incredibly real on the other hand.
