At $108 this seems like outstanding value given the hardware/specs. Emphasising value because there'll still be several trade-offs at this price point.
Don't forget CR/SB for additional sweetness.

It says 240v, but where is the power input? The yellow one next to USB looks like a digital output. USB powered the same time as sound input?
