UMC404HD : Probably the best you can get for this price.

Bought this for home use, so that I don't need to go out to record, and my old AI was having it's last days. TL;DR - it's great. Noise levels are low, the preamps are very good, there's enough gain, pads for every channel as well as other creature comforts. The unit feels very sturdy as it is all made of metal, the knobs feel very good, smooth and heavy. Installation is pretty straightforward, took me about a minute and bam, it works. Hooked up to my studio monitors, it is very silent. The playback is clean and crisp, not colored, very neutral, which I personally value a lot. Overall, the only small gripe I have with it is that the phantom power switch is located on the back of the unit, which can be annoying depending on your setup. Other than that, I honestly don't see why anyone would take the scarlett over this. Sure there are better units, with even quieter preamps etc etc, but not at this pricepoint nor anywhere close to be honest. A very good unit, hope it lasts, absolutely do recommend.
