Best practices when conducting a DAC comparison

I would also ensure all the components are broken in, especially the Terminator DAC.

@gdhal 

Got it. No, I don't want to mess with Mr. Zhao's flagship work!. : )

My main output is USB from a Sonore Signature Rendu SE.

I'll primarily be focused on comparing the USB input between all DACs.

@muzikmann  Yes, especially the Terminator. The manufacturer advises 300-500 hours; and yes I know how some feel about this. : )

As @toddverrone mentions in his post, spending time with the components will also help accomplish this.

I will start with the critical listening for the Terminator towards the end of November. I'll energize and run signal through it 24/7 until that time.

I'll also keep the Yggy and the Comet energized. 

You are certainly being thorough.. I'm interested to hear what you find. Keep us posted!
