Title: Qutest DAC output voltage
Post by: Audioraider on December 07, 2020, 12:09:23 PM: Would it make any difference running my DAC output voltage at 2 or at 3 volts into my Mainline other than volume level? I am curious as to whether 3 V presents a problem for the Mainline?

So as to stay well under the heat stress (W) rating of the attenuator resistors?

cheers and thanks, Derek

Ok, so 40v in a no go.... I guess Iâ€™m ok at 3 then lol
