I've had the Mojo for two days now and here's are my impressions compared to the Bimby (Bifrost Multibit).
I used the line out of the Mojo to Gustard H10 with JH13pro and Grado GH1.
At first they sounded similar, similar tonality, presentation and similar details. But there was still something more about the Mojo. Upon further listening this is the difference, focus. What do I mean? It's like the lens of a camera.
With the Bimby I see everything but it's a little out of focus. It's slightly blurry. Therefore, the Bimby sounds soft and warmer compared to the Mojo. The Mojo on the other hand is like a camera lens perfectly focused. No blur at all. It's clear and clean.
In this way, the Mojo compare to the Bimby sounds more colder and clinical. Not in a harsh way but it the sense that it's more transparent--more focused.
Honestly, this little Mojo as a Dac is amazing. The imaging and resolving power is astounding.
As for the amplifier, considering it's size and portability, it sounds great. But I don't think it can be compared to a really good desktop amp which I think one the post alluded to before he got bashed.
Maybe it was the way he put it. Right now I have the Mojo connected to the Vali and Gustard H10 and while they both have their unique qualities, I find it better than the amp in the Mojo to my ears.
My future plan ultimately is to pair it with the Cavalli Liquid Carbon (for it's special and unique qualities) to take advantage of the Dac more than the amp.
