Roland Rubix44 USB Audio Interface

The most obvious feature that sets the Rubix44 apart from competition in this price point is the fact that it includes 4 Combo jack input channels, as well as 4 line level output channels.

To sweeten the deal they've powered these 4 channels with Roland high-quality pre-amps carefully designed for pristine sound and low-noise performance.

And perhaps even more critically, Roland have put particular emphasis on high quality AD/DA conversion, allowing  warm and clear high-resolution audio up to 24-bit/192 kHz, which is practically unheard of at this price point.
