Just got myself an Audient ID4 (mk2). Not that i had anything against my Motu M4, but i kinda realized it was overkill for my needs and I really wanted the smaller and more portable aspect of the Audient. It goes very well with my MacBook Air. And being able to move and use them in whatever room I want to be in is nice. The looks is a bonus. (I admit that my Apple space gray fetish may have an impact on my gear choices… if it looks and feels good… it’s good)
The sound is a subtle matter… I guess playing music through both I don’t hear any big difference, maybe the Motu is more “sterile” and hi-fi. I’m not sure. The Audient sounds great through both headphones and monitors. It’s a full and vivid type of thing but doesn’t strike me as hyped anywhere. There’s something there and my limited experience on interfaces can’t put a finger on it.
Regarding guitar input. The Motu seems to have an upper hand with its drivers and the excellent latency performance. The Audient also has good drivers it seems, very capable and the latency differences doesn’t matter it seems. I certainly can’t feel a difference. 48k and 32 samples is my safe zone and both seem to have the same reported latency (a neural dsp app…. Which we can’t really trust but at least it’s a hint that my m1 doesn’t care much about which interface I use).
But when it comes to input, to my ears the Audient definitely does something I like with its “special” jfet input. A di from both sounds different and I prefer the Audient. People may prefer their di untouched and not messed with, but I like it. Running it through plugins I’d be hard pressed to state that there are a huge or meaningful difference. I won’t run them through some analytical madness things, I’ll just use my ears. Just maybe I can hear a hint of more “life” or warmth in the Audient input vs the Motu.
This reminds me a little about the Strymon Iridium which also has this… input “feel”. The Audient input can be made to “sag” or “give” if that makes sense… it definitely behaves more like the preamp/boost/fairy dust pedals I’ve tried, than an audio interface instrument input in that regards… which kinda makes me smile as an old pedal nerd. Again… like the Iridium.
But the Motu would be the more studio performance correct input… I think. I’ll leave that to the studio audiophile think hats.
Nonetheless I’m keeping the Audient, and selling the Motu (seems to sell like hotcakes), it’s a great box for my needs and appeal to my portability thinking. And I love love love that master wheel and the speaker/headphone quick button which toggles between outputs fast. Very handy.
