As it comes to sound, the 1st gen Scarlett 2i2 was limited to a sample rate of 96kHz. However, the 2nd gen 2i2 now supports up to 192khz sample rates with a 24-bit resolution (but, who records at 192khz anyway?). I've been using a 1st gen Focusrite Scarlett 2i4 for the past 5 months. It has turned out to be very reliable and it works great but the only thing I don't like is the latency. I wanted to try out the 2nd gen 2i2 since Focusrite managed to lower the overall latency considerably. .
