Welp... I've been thinking about get the Massdrop 789 for a while now but maybe I'll just wait for a different company to come out with a balanced headphone amp with THX AAA technology. Dealing with Massdrop is a huge pain in the ass. I have no idea how they can have a product with such high demand and they completely leave their customer base hanging for months. I do have one question though, does anyone have any opinions on how the 789 compares to an Audio GD NFB1 amp? I have an NFB1 amp that I am happy with but all the positive reviews about the 789 have me curious about it. I've only seen one review on YouTube comparing both briefly. Is it even worth getting a 789 when I already have good balanced amp?
