Esoteric and Yaqin


The issue brings a question. I have an Esoteric K07 SACD player that can also perform as a DAC. I have what is a suprisingly nice Yaqin CD player, built like a Sherman tank and sounds pretty darn good. I moved it from my secondary system to the main ... next to the Esoteric. I've purchase, but have not yet recieved, DH Labs digital cable. I got this idea to use the Esoteric's DAC when playing the Yaqin. The Yaqin has two Northern Electric output tubes .... so the analog signal runs thru the output tubes and on thru the system. My question is, when connected to the Esoteric DAC, am I bypassing  output section of the Yaqin and therefore the influece of the Yaqin tubes? I must be. Thanks for the help.

Yes correct you will output the digital signal to your Esoteric it will not go through the analog stage of your Yaquin.
Thank you. Then another quesiton, if I may. Let's say we have a tube CD player and a tube pre-amp or even tube amplifier, how do we know how much of the source tubes are influencing the final signal? Would not the pre or power amps masked the sound of the source? And if so, what's the point of having tube sources if your pre or power amp are tubed? I'm sure many have an answer, but this has just come to mind for me.

No, not if the tube preamp and power amps are neutral. They'll simply pass the signal that is fed to them.

If you're choosing components that deliberately distort the signal, then that's another story.
