If you're hell bent on using the line outs to monitor, either listen at full volume all the time, or put something in your signal chain that you can use to change the volume in the analogue domain.
I think the question we should be asking is that if the Dual DAC's garner a significant improvement in audio quality. Why weren't they used on the monitor out???
Good replies to that question. Here's the thinking. The Line Outs were intended to be the analog output for the most critical usage. That's why we designed it the way it is.
If you go to our website and compare the specs between the Line out and Monitor out, you'll see that the specs on the Monitor out are still pretty darn good, -107 dB THD+N; 121 dB dynamic range; -130 dB crosstalk; and +/- 0.02 dB freq response 20 Hz - 20 kHz. This is pretty darn good. And these are REAL measured specs, not estimates or preliminary.
Now I don't want to get into a specs war here, but in practical applications, for a monitor output with a volume control, this is hard to beat. And the Line out is even better, but that performance, as you note, would be compromised by a volume control.
You are also correct in that we do not have a digital volume control in the Line Outputs. We do however offer digital output level controls on the Monitor and Headphone outputs.
The bottom line is that all three analog outputs, Line, Monitor and Headphones sound really, really good. I do not have golden ears, but I cannot hear any difference between the Line out and Monitor out signal, and I have tried this directly into both Tannoy and Genelec monitors.
