Best practices when conducting a DAC comparison

Thanks, Todd. I think you will appreciate what follows.

My main concern is that my current system has been (mostly) optimized with the Schiit Yggdrasil within it. I struggle with this very issue in the comparisons and component evaluations I read, whether professionally done or owner based.

I’m especially concerned about cabling.

I recently completed a USB cable comparison. It was difficult yet very educational. I’m well aware that the cable I found to perform best to my preferences and goals may not match as well or deliver the same outcome with the Denafrips DAC (again to my preferences).

For example, I chose the Cardas Clear Reflection XLR ICs for my headphone system. They are performing very well in the 2ch system, but the choice was made for a different application and goals. Would another brand of cable or moving up the Cardas line-up be a better fit for my 2ch system, with the Yggdrasil in it? For me, the answer is likely.

The ’million’ dollar question (for me):

........ is using the same cabling across the different DACs the best way forward?

OR

........ is it better to compare optimized systems, with the components standing on their own within them?

I believe the second approach has a greater degree of fairness in terms of determining endpoint differences and performance preferences. It, of course, is not nearly as practical or financially feasible.

[Note: At a minimum optimizing around the power and signal cables in and out of the DAC is a somewhat more viable option]

I realize we have a number of Audiogoners who find none to minor differences between cabling. I respect this. Further, keeping the cables identical will make the process straightforward and much, much easier for me.

For those of you that do find cabling an important piece, I’d love to hear your approach to this. Thoughts? Thanks.

The best measure for me to demonstrate the quality of the low end is the Beatles "Come Together" test. The first break where Paul let's his Bass "A" string linger out ("Joker do what he please"). Even if generally listening you cannot tell the differences between dacs, amps, cables....this one little passage will give it all away. You'll know it when you hit a sweet spot because you can feel growl of the bass string. You can switch components and notice that something is missing. This isolated bass snippet is copied and pasted a couple of times in the Beatles LOVE soundtrack as well.

........ is using the same cabling across the different DACs the best way forward?

Both ways is technically best from a comparison and arrival at conclusion(s) perspective.

@david_ten,
I am rooting for the Terminator because I have been following it since its conception, it has been tempting my wallet for some time now.
