Are those rigs ipods by any chance? If so the second "amp" is actually a USB dac like the CLAS. Same with some smartphones and maybe there are still some old irivers in use too.
There shouldn't be need for more than one amp!
The iPods HP jack where headphones/earphones plug in to lizten music and line out signal pass through dock connector where charging cable plug in. Line out signal are more cleaner and improve the soundquality with external Amplifiers help, both sony walkmen with WM_Port and iPods offers line out signal tonconnect with external AMPs.
