Specs on the LM4562 shows 13 ohms. What do you feel is the overall output impedance of the single ended output?
Are all those resistors in the signal path metal film?. Are all those really necessary?

All of the resistors on the IVY are very low noise precision (0.1%) metal film resistors.

Its a lot lower than 13 ohms!!! That is the open loop impedance. Of course the BAL/SE section is a closed loop. The impedance will be in the some milliohms. :)
Yes the precision is necessary for best results. :)
