Parametric EQ ? Is there one and will it keep the signal Hi Res?

Volumio Information

Volumio Version: Not bought it yet - but planning to
Hardware: Primo + Mutec MC3+USB
DAC: Mytek 192 DAC

Hi is there a parametric EQ plug in downloadable?

Does it cause the audio to be downsampled? Or alter the bit depth?

Many thanks
