Impedance-matching in audio amplifiers: The DIN vs. Line/RCA problem

When connecting audio equipment you have to take care of the correct ratio between source-impedance and load-impedance. Plus the properties of the used cable.

In contrast to RCA/Line-connections, DIN-connections are totally different. They are current-sources! Especially cumbersome is trying to connect a DIN-source with a Line-load and vice versa.
