Cables to settle brightness

Mc system: 601s and a c2300 and SF Olympica. My speakers cable is Wireworld equinox. So not an overly bright system by any means.

I should note that vinyl doesn’t have this issue, just digital sources, so cables to the digital source might be the place to start. 

Turning the treble down certainly helps, but, as a purest, I would prefer to not use the EQ

Upgrading my DAC took care of this..using AQ Earth.

Interesting idea about the DAC. I’m currently using a Mc DA1 module in a MCD85. Perhaps as I’m improving my power/amps/pre I’m revealing a deficiency in my DAC. I’m also getting sibilance now with female vocals.

There are several possibilities. Based on my limited experience cables may help fine tune the sound by reducing the brightness but the difference may not be significant enough to completely resolve the sibilance with human voice or glare in the treble.

In my system, the amp and speaker match is usually the culprit with sibilance and brightness. Replacing either the amp or speaker resolved the issue. DACs don’t contribute too much to the brightness in my system. As a matter of fact, one of my DACs (Luxman DA-06) sound slightly warm.

I would look at trying different amps if you like the sound of your Sonus Fabers.
