Thanks Simon, that’s helpful reference.
I didn’t realize you have the Altair G1. I think we do share the same concern with the output impedance of 4.4 Vrms (4.8 Vrms for Vega G2 per specifications). The difference with our concerns, which is between Vega G2 and Altair G1, is Vega G2 has he analogue volume control which, once set, does not affect SQ. I think Altair volume control is digital so if you lower to anything less than 100, you will reduce SQ.
That is why I am trying to get clarification from Auralic on whether the LDS output trim also cuts output impedance like the volume knob on the Vega G2 without affecting SQ. Or if it is just a software reduction in volume which would be different than the analogue volume control and would affect SQ.
When Xuanqian replied that LDS output trim does not change output impedance level, that’s where I am confused and start to think it is digital/software controlled volume which affects SQ. If that is the case, I should stick to LDS output at 0 and control/lower output impedance by using Vega G2’s analogue volume control.
As well, if Auralic provided some sort of graph or curve similar to what you had provided, would be very helpful for many users.
