Read a good review from a mag on it. It will explain it in detail. Seems like it won't be enough for your needs. Yeah an amp amplifies power, volume, not to be confused with gain which distorts at higher volume levels. The Dac allows the sound to be processed to mono so you can hear it, better in some cases I assume. Those Fidelios are power hungry so definitely bigger amp. I still use an old OB Creek amp I got in like 2000.

Should be perfectly fine.
Also, how does it deliver the power? Is there a way to control it?
The volume knob on whatever device you've got it plugged into.
That's what I don't understand, does it mean the phone buttons, or the laptop slider? If so, I have no control on what the DAC does, it is just a static amplifier, or is it linear - the higher I set the volume in my phone, the more the amplifier will boost (Making it almost increasing by factor of 2 for each level I increase the sound)
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?
I use KA1, not sure if it gives sound quality improvement over the 3.5mm jack, but for sure it completely remove the noise in audiobooks during chapter changes.
