Can it be used as a preamp? I intend to use it to drive the Adam A4 active loudspeakers.
Yes, the Lindemann Limetree USB-DAC can drive the ADAM Audio A4V active loudspeakers. The DAC features a built-in analog volume control and a stereo RCA line output designed to feed active speakers, while the A4V monitor includes unbalanced RCA inputs that match this output.
