Hi
Today I was experimenting with my two RPis and HifiBerry DAC+ and
HifiBerry DAC+ pro. Material used was Gidon Kremer's rendition of
J.S.Bach Partitas which is quite harsh on any digital equipment. After
much tweaking, A/B testing and more tweaking I finally found the right
spot for two sub-optimal Kanto Yu2 speakers and the RPi3+DAC pro.
- In alsamixer set Analogue gain to zero
- set the DSP Program to FIR interpolation with de-emphasis
- on LMS set output level to fixed to 100%
- on the piCore install the alsa equalizer under Tweaks beta.
I got awesome results with these equalizer settings:
