Oh sweet on the Mojo, that’s likely to be a solid dac going off the Evo (not heard the x so can’t comment exactly there), and also that’s a logical yggy upgrade in my mind as well, should be pretty nice, will be curious on your thoughts
Generally for how I feel vs the totaldac, I think from a technical level they are probably close and trade blows (going off an Evo B4B at least), generally signature wise the mojo is more clearly warm, along with a more forward presentation overall, whereas the totaldac is more neutral (but still warmer leaning) and isn’t as forward. When it comes to tonal density, I do think the mojo is overall richer and more weighted, but the totaldac feels more balanced and convincing with it’s weight. For resolution and low level detail they might actually be similar, both present it pretty organically too although the totaldac might have a bit of an edge there. When it comes to speed and speration I might say the mojo actually feels a bit more snappy and separated although sometimes unnaturally so. Dynamically both are very strong, with the edge in macro actually going to the mojo, but micro going to the totaldac. Timbre wise, it’s a toss up, both are really good here, although I would lean more totaldac potentially. Texture wise both are also very solid once again, but I think the totaldac represents it in a more accurate way, but the mojo emphasizes it in a more pleasing way. Spatially I’d say that the mojo offers better depth and placement sharpness while the totaldac offers better width and placement organicness, again both do well here. For stage blackness both are great. For overall coherency and liquidity I think the totaldac might pull ahead but the mojo doesn’t have issues with this either. For raw impact and slam I do think that goes to the mojo, for overall control and grip it could go to either, also potentially slightly leaning more toward mojo here in the bass (but the totaldac seems to have better control of the rest of the range). Extension wise the mojo does feel better extended in the treble than the totaldac since there’s a bit of roll off there, somewhat similar in the bass. I think overall the mojo does have some exaggerated contrast in it’s sound where the totaldac is more faithful there, just something to note
As you can see, they trade blows fairly well, and I think it will really come down to what you prioritize, if you want a stronger macro focus that’s more energetic, rich, and noticably colored, the mojo is your pick. If you want something a bit more neutral and refined/composed with more overall balance but still a bit more warm and organic leaning, the totaldac is the play. I do think these dacs go for a somewhat similar goal and have some similar strengths, but there’s reasons to go either way tbh, don’t really think you could go wrong with either. Also to be clear here they don’t sound all that similar, they just focus on similar goals
Either one should be a big step forward over your yggy. I will also note that both these dacs are reasonably sensitive to the incoming digital source and greatly benefit from a nicer digital signal so that’s something to consider down the line
Also I forgot to note it, but my experience with the single mk2 is only with it having the live power upgraded psu, I’ve not heard it with the stock power supply so I don’t know how much that improves it over stock
