> [@beatom](#): > > Hi @djgorey, as stated above, this issue has been resolved with the last update. As I said, that’s not quite correct. My point was that the other sound problems are worse than the roll off and particularly even more so now that the roll off has been reduced, so if people have a problem with the sound it’s unlikely the roll-off is most of the alteration they’re hearing. That doesn’t mean there isn’t roll off, just that the nonlinear harmonics and IMD is substantially more coloring than the slight roll off remaining. And as I said in the post someone flagged, VDJ, Traktor, and Deckadance aren’t bit perfect, either, but their sound, unfortunately, currently puts Prime to shame. > **[Denon SC5000 Prime - Page 10](https://forum.djtechtools.com/showthread.php?t=93197&page=10&p=765578&viewfull=1#post765578)** > > Love the hardware cue buttons despite having the (multi)touch display. > Loop/loop move encoder! > 2(3?)

I ran some RMAA tests of the Hanpins, Pioneer CDJ-900, and Gemini MDJ-1000 playing off a flash drive. All done using SPDIF out. For MP3s, 320 was a significant but not alarming reduction in specs for all three brands… I don’t believe that’s shown, but take my word for it. VBR was substantially worse (red line with wild high frequency swings), and they pretty much decoded MP3s of varying types similarly as f… --- _[View the full topic](https://community.enginedj.com/t/16khz-lpf/16212)._
