I tested this. (IQ audio Dac Pro) It has a clear, clean sound.
Unfortunately The treble (ie >2kHz) is piercing and sharp, and it makes me think this DAC does not have a flat response.
I much prefer the sound-card of the old laptop.
With the Same Amp and speaker setup:
When comparing to my laptop sound card (no effects or equalisation enabled)
with the IQAudio DAC pro+ on a Rapbserry pi 3..
The difference was obvious,
The High tones were piercing, female vocals and cymbals were unpleasant and sharp. Things only sounded normal after dialing down the treble on the amp. What detail am I missing out on now.. ?, by cutting down a chunk of sound with the dial.
With the old laptop setup, the Amp equalisation settings can be at dead-centre, and the sound is 'balanced' and full.
I thought I would share my encounter, has anyone else found similar ?

PCM52XX DACs all sound like this. One implementation is better, other is worse, but they all have the some unpleasant high frequency behaviour.
I wonder if this would help Avoiding RPi Master I2S Fractional Jitter . That DAC is certainly slaved to the jittery I2S.
