I understand the need for a volume control and to have the impedance's low for the streamer/DAC and high for the power amp. My streamer/Dac is <100 ohms and the power amp is 47K. There is an implication that the preamp does other things that affect the SQ. Any idea what those are? An Allegri+ addresses the impedance problem and give a volume control and is extraordinarily transparent on my Ribbon Speakers. My amp and steamer is very high end. Is there more?
Perhaps the amplifier maker hopes you will buy his preamp. You are correct, there is no need for one.
