That thread is a good reminder is always turn on amp/s last.Wouldn't connecting a DAC directly to a power amp risk frying your speakers if there's a bug in the DAC firmware that randomly resets/ changes its output volume? See horror story linked below.
Not trying to save this particular product, just asking as a newbie.
I don't know why but today when I switched on the Topping D70S the volume was at -0db. Of course, i never set the volume so high, and usually the dac reminds the volume of the previous time, but not today. Result: the amplifier fried the tweeter of one loudspeaker. I don't know what the Topping...audiosciencereview.com
And check the volume level before you turn on amp/s.
