Pioneer Dj CDJ-3000 master tempo test and comparsion

I compared the performance of the Master Tempo algorithms in the CDJ-3000 and CDJ-2000nxs. I can say that the old 2000nxs can still do it! In fact, the difference is small, sometimes it seems that the CDJ-3000 sounds better, and sometimes the CDJ-2000nxs sounds better. There is definitely a difference in sound, it is audible at extreme pitch values. The CDJ-3000 has more detail in the high frequencies, but at the same time, artifacts have increased at these frequencies. The CDJ-2000nxs has more detail in the midrange. There are obviously differences in the code. In addition, in the CDJ-2000nxs the algorithm is executed in a specialized DSP chip from Texas Instruments, and in the CDJ-3000 in an application on an ARM processor. In the pitch range of +-24%, the difference between the players is impossible to notice.
I compared MT CDJ-2000nxs and nxs2, I didn’t notice any difference. This is not at all how the increase in quality between CDJ-1000mk3 - CDJ-2000 - CDJ2000nxs was heard.
This suggests that the optimal key hold algorithm for real-time systems was developed more than 10 years ago and it is difficult to improve it.
