Just got the Magni Unity in. First want to acknowledge the awesome customer support from Schiit, as my first unit had a faulty left RCA input. They had a replacement to me within a few days!
I got the black unit without dac, as I'm connecting to a Modi+.
Dang, this thing sounds GOOD. Like, I'm pretty surprised that I not only notice a difference from my Magni Heretic, Magni+ and FiiO K7, but that the difference is as large as it is. The difference between the other 3 is tiny, but this Unity stands out.
Stage is wider than all of them- probably the most obvious difference. Highs are silky smooth. Low end feels more natural, maybe faster or something? Also this is going to sound like BS, but I feel like the very small nuances of the sound are brought out- stuff that I don't really hear on the K7 for example, I can hear it on the Unity.
I don't listen loudly, 65-70db, and I still can notice a difference. The best way I can describe it is- for those that love the 6xx/650, you know how if you use other headphones and come back to the 6xx/650 its always this comfy feeling? Almost like an "ahhh" relief. That's how the Unity sounds to me. I switch back to it and it just feels relaxing and enveloping.
Also I don't know what the heck this thing is doing but I've never heard drums sound so good. High hats are smoothed but still detailed, and I feel like I can hear more detail in drum hits and such. Really hard and weird to describe.
Did I mention orange is my fav color? The LED pleases me.
And to answer your question, yes. The Unity sounds better than the Magni+ and Heretic...somehow.
I'll echo my thoughts on most of their products- this thing is ridiculous for the money lol.
