What function do the output buffers perform when driving 300 ohn cans?
In the explanation of the circuit, Tangent notes that the opamp is looking at 200 ohms in the input of the buffer. If the buffer sees 200 ohms in the cans, how does it help? One member got by my screw up in first asking this question and said that the buffer helps with hard to drive cans. But if an opamp can feed a 200 ohm buffer shouldn't it be able to feed a set of 300 ohm cans? I could see it having trouble with low impedance phones.
