Well the DAC doesn't "boost" anything, it takes a digital 1's and 0s and creates an analog signal from that.
I'm not an expert on the finer points of USB audio, but presumably when you twiddle the volume knob on your phone or laptop, it writes to a volume register in the DAC chip, which sets the amplitude of the output accordingly.
So I need a DAC and an Amplifier? Is there dongle with both?
