Most PC/ monitor speakers have build in amlifer so they don't need a power amplifier!
So another mini hifi system will not includes the A1, but it will be more convenient with our E9, because most of the monitor speakers have two volume adjustment!
and it is hard to balance the left/right channel to the same level! now E9 can solve this problem!
BTW, E9 have two output jack on the back pannel! one is constant line out which the output level is in 2V rms, one is pre out, the output level is adjusted by the volume of E9!
Below is the diagram!
