Hello,

I own the MiniDsp DDR-24 with Dirac Live. After measurements and using Dirac recommended filter, everything is better, except the voices (male & female), They seems to me more edgy and "digital". Is there any way to improve in this aspect, modifying the recomended Dirac curve?.

I have already replaced the original power supply by a lps and the usb cable by a Supra 2.0

Thank you in advance

We could be wrong but I doubt that the USB cable or power supply is the issue here.. It's most likely these 2 issues:
- Overstressing your speakers. Make sure that your target curve is BELOW the natural response of the speakers. Too much boost will make your speaker sound edgy as you're overstressing them.. it's physics.. :-)

- Other potential issue is that you're boosting too much and clipping somewhere.. Make sure that you have enough headroom inside the DSP at the input..

Last but not least, the target curve is your key here.. that's what you want to play with until you enjoy the results. It takes some times to adapt to your taste.

Not the OP but how would one go about doing this?

In my experience, edginess and an electronic sound are most likely caused by too much output around 4kHz to 8kHz or maybe a bit higher. Try sloping the target curve down a few dB starting at 3-4 kHz, and see if that sounds better.

Yes,this helps a little. Thank you very much.
