I had a chance to look inside the latest Benchmark DAC1 and this is what I saw.
It has a single circuit board for everything including the power supply, receiver, ASRC, DAC, and headphone amp.
The headphone amp has two BUF634F buffers, two 5532A opamps, and a really small alpha pot.
The receiver is the AK4114, the async sample rate convertor is the AD1896A, the DAC is the AD1853 followed by four 5532A opamps.
A LC02A and RX176 is in there also. Four more 5532A opamps are by the output connectors.
The power supply has a three inch torroid, two TL401 rectifiers, a 7818 pos reg, a 7918 neg reg, a 7805 reg, and a LM1085.
Looks like there is plenty to modify in this thing.
