This is your personal opinion. Measuring plenty of consumer audio products and designing my own ones during past 20 years tells me something else. "As discussed yesterday" argument would not convince me, hard data do.As discussed yesterday, there is no "usual 2V output level" for a line out.
This is measured at amplifier output playing Tchaikovsky 1812
For 35Vp output voltage with 26dB gain amp I need 1.75Vp input. This is just one example.
Digital source data are this:
So what, are we talking about 150mV line output???
