Thanks @Ableza - according to the TI data sheet, the input impedance ranges from 60k-ohms to 9k-ohms depending on the gain (see section 7.3.2 in the data sheet). I don't know what happens to a chip amp's input impedance if it's powered off. But in any case, that doesn't sound super-low in theory.In general it is fine to connect all outputs of a device to an input at the same time. The only time this a potential problem is if one or more of the amplifiers or preamps you connect to has too low input impedance. I know nothing about "Nobsound" but I am always warry of cheap Chinese chip amps...
