UMC1820 : The BEST interface (for the money)

This thing is absurdly cheap. It's basically 1/2th to 1/3rd of the price of its competitors such as the Focusrite Scarlett. The pre-amps on it are OK (I have been told they are the same as the ones on the X32 but they seem a little noisier to me) but the fact has ADAT and SPDIF is very useful for connecting it to legacy sound gear.

There are however some drawbacks. The build quality is quite poor and the casing bends easily with moderate force. It would be nice if it had 2 ADAT in/out ports so any external ADAT gear could be ran at 96khz rather than 48khz and the lack of a word clock sync is a major disadvantage when utilising ADAT/SPDIF connections with some equipment. The external power supply is also unnecessarily bulky for what it does and I don't know why they didn't go for an internal one - but, you don't always get what you want and this thing really is fantastically good value.
