A/B testing an old school vs. new school mastering setup

Hi! I'm A/B testing an old school vs. new school mastering setup. Which version of this track do you prefer?

Version "CCA9":

Version "CE0F":

I think I prefer the first one - Bit more physicality to the sound, the second didn't have as much brightness in the mix in my opinion.

Hi!

CCA9 for me (without the hiss, maybe). CE0F seemed more in-your-face, too much for my liking after hearing the other one.

i like the first one[cool track] better but the hiss…...

Interesting, thank you all very much!

How about between just these two?

Version "0e42":

Version "63db":

0e42 sounds sort of more detailed but also harsher. And during the outro it sounds almost like it's trying to normalize after the beat stops, just like CE0F above.

So I think I prefer 63db, the only thing better about the other one is that it simply sounds louder (which is a serious confounding variable, I think levels should be matched better for proper testing).

0e42 for me this time, as manmower mentioned there seems a lot more details in the sounds. It emphasises the nice analogue imperfections of the pulse/saw (is that then classed as PWM ?) plodding basseline.
