ahh ok well it will be the 180R I was just going by what we do in the valab and what I have done in any passive I/V set up in any of my dacs. the I/V are usually the last set of resistors to ground before the output, I would assume your 47K are not standard and just something you put there to tune for your amp in particular?? at a glance I only saw the one set, 47K is far too large for I/V. the 340R in the valab are the I/V, in any dac i've ever built the aim is to keep the output impedance as low as possible, so it didnt even cross my mind there would be another set just to make it larger.
