Sound quality of the Headphone jack

[CzarofAK]

I thought about the Raspberry Pi Audio output quality.
For my speaker i am going to derive a bit from your configuration.
There are two different possible ways for me to realize a better Sound output quality:

1. Keep the Display but use a USB audio card such as "Sandberg USB to Sound Link" or "Creative Sound Blaster Play!3"
2. Leave the Display away, and use instead a Hifiberry DAC+ with stereo cinch output

Hi @CzarofAK maybe fork this project and we can pull back anything that is worth doing?

The casing is exceptionally tight, as ideally the KMTechs would have been better all on one board. Maybe in future I could make the crossover, but there is an audiophile skill there to set them that is probably beyond me.

The 3.5mm jack was only of minor annoyance, so I am betting that a USB Creative Sound Blaster (and that its on a cable allowing perhaps to put it in a gap between the Pi or KM Techs) may work out.
