Arturia AudioFuse Studio

PROs
-Preamps are really good, quiet and have lots of gain, more than enough headroom, for reference 60% gain can drive a Beta58 loud enough.
-There's no other option on the market that have so many I/O and in a desktop interface size
-there are a lot of buttons and some of them are configurable, convenient for working quickly
-2 pair of Speaker out and 2 headphone out is great to have, though there is only 3 monitor mixes (good enough to me)
-Headphone out is powerful enough to drive K702 and HD650 at 50-70% volume
-Bluetooth is handy, very happy to have, but do not expect the quality anywhere close to the wired inputs
-USB cables that comes with it feels sturdy and looks cool.
-work smoothly on both my mac and PC without any issues at all
-Love the USB hub function, especially if you are a macbook user like me
CONS
-It can get a bit warm when in use but acceptable.
-Latency is not as good as the thunderbolt interfaces, it's USB 2.0 afterall

If you want an interface with 4 quality pres, 8 analog input, expandable, portable and do not need DSP, this is a very good option

I sold my Apollo Twin mkII for this and it’s definitely worth it!
Great monitoring capabilities with three presets available directly from the interface. (You have to set them up in a computer but after that they’re standalone)

I have two gripes with this interface.
One is that there are no mute switches, a thing I’ve grown accustomed to with my gear hooked up to a mixer in to the apollo interface. This way i could mute noisy stuff but still have it set up for quick recording.
This can be worked around by having cues set for muting but then you’ll lose cues for live recording with other musicians.
The second gripe is that you have to use the software for setting up the interface and make changes to it, for example, setting it up for re-amping. This is normal interface stuff which I had with my Apollo and my old Liquid Saffire but for me, about to make the change from mac to ipad recording, it’s annoying that i cant use an app for it. But for normal pc/mac users it’s no issue.

I love all the connections and they help a lot in building a hardware based, as little daw as possible, studio.

Great sturdy construction.
Great sound!
Nice preamps!
Two headphone amps!
Re-amping and two monitor sets!
Phono.
Midi!
Blue-tooth was a surprisingly nice feature.

I won’t miss my old UA interface!

This has really given me an all in one option to handle any possible scenario in a home studio. Want to use a guitar with an amp sim, sure. Have a friend with you and want to jam out with some midi instruments... two headphone outs. Have an old turntable and some vinyl to sample... phono in (also doubles as a rca line in). Want to quickly switch from speaker A to B to hear how your mix sounds on other speakers... press a button. Have a singer and a couple instruments to plug in... up to four. Basically, I can't imagine a scenario it cannot handle for a home studio and it has more features than I'll ever need. I've done all these things and it was wonderfully easy to work with. The only thing that ever tripped me up was learning that to use loopback, you must be using a sample rate of 44100 or 48000. Thank you, Arturia for making such a wonderful piece of equipment.

It took a while to do the research and convince myself that this is worth so much money. Well, this show only that I never invested in a real-real interface. My most expensive was the Presonus AudioBox 1818VSL...
Thank you all other reviewers at Thomann's for the last ”nail in the coffin” of my decision. No, seriously, I was sure that this is going to be good when I ordered, but it's more than that. It's just great for my needs, and the sheer knowledge that I'll also be able to expand it through ADAT sends from my old interface if ever needed, awesome.
The preamps are really great, I could even run some truly lazy mics like the Shure SM7 that I borrowed for a test, as wll as my own large diafragm mics, one of which is another lazy one - Aston Origin, don't trust nobody who says it doesn't need extra gain...
Then my matched pair of Oktava MK-012 (which I also bought through Thomann) that also sounded great sith the pots at around 11:00 close miked and at 16:00 some 50cm away. Didn't get any significant extra noise there.
Just look at all the functions, Bluetooth included, I play my gramophone through it, reamping is a new field but worked great as soon as I understood what I needed to do.
It's small on my table and fits great just underneath the monitor, I drag it out closer when recording, I'm in heaven.
A friend who I recorded with noticed that the main volume knob was ”lazy”, meaning that he needed to make it several turns to incresse the volume significantly and yeah, it's true, but I call it precision...
Great buy, go for it!
