Is there something I could ask Doug Dale at Coda to do to limit the output voltage of the balanced outputs?I presume you meant to refer to the amp’s balanced inputs, not outputs. I would recommend against asking him to do anything to make the amp more optimal for use with the high output voltage of your DAC, because it would likely make it less suitable for use with whatever DAC or other source components a future purchaser of your amp may want to use with it.
What you might ask him about, though, is if it would be feasible to drastically increase the input impedance of the amp’s balanced inputs. Very few tube-based source components can drive 1K properly, and many solid state source components would have trouble as well. So if it is practicable for him to make such a change, it would increase the amp’s versatility.
Why do you think this voltage is so high here? What would be the intended equipment to run balanced at this voltage?
I have no idea. (And btw the unbalanced output voltage of the DAC is also far higher than usual). My initial instinct was to suspect that the high output voltages of the DAC might be optimal for use with W4S’s own preamps and integrated amps, but looking at the gain and sensitivity specs for their currently produced models (which are fairly normal numbers) I doubt that is the explanation.
