    RCA splitting: Why is it able to send full output to 2 devices?

    So this is a basic and very dumb question, but I am currently splitting my DAC line out RCA to a set of 2.1 speakers (Corsair SP2500, old and poor quality I know) and my headphone amp. It is my thinking that, should either the speakers or the amp be the only device on, the full output of the...

Does my headphone cable have to be balanced also to get the benefits, or is it enough that I am plugging it into...

    Accidentally connected 3.5mm line out to RCA preamp out - could this have affected my gear?

    Hey all, very basic question incoming.

(So basically, a 3.5mm line out on the Topping...
