Yeah, I don't think I could get by with a single input device.
I would regret that decision.

The 2i2 is a nice unit. I have one for 'in the field' recording use.
Grab it and go type stuff.

I have Behringer preamps and Focusrite preamps.. I wouldn't call the Behringer ones noisy or anything (they work fine), but the Focusrite preamps are cleaner to me. I use them whenever possible.

Another caveat/tradeoff is the Behringer headphone out is louder then the Focusrite headphone out, which simply means I have to turn the headphone dial up more on the Focusrite.

Funny part - my main system sends two of the Focusrite outs to a Behringer headphone amp so I can have multiple sets of headphones. <grin>
I have nothing against either brand, just my opinion on quality.

I do not work here, but the benefits are still awesome
