Hi nassost79,
Since you are still building your player, I thought it a good idea to show you mine. You might fetch ideas from it.
Have a look at these pictures:

I built it from a yamaha tx-500u tuner from the eighties. Got it cheap from ebay (35Euro). Who uses this kind of tuner nowadays?
I added 2 large analog vu meters to give it a vintage look. The display is a 16x2 oled one. The bezel around the display is from digikey.
I have 10 hardware buttons on the front of the player (1) that are mapped to several playlists, and 4 other buttons (2) that are used for play, pause. next, previous. I use moode audio. A script is used for those buttons.
I use a yamaha IR remote that came with the yamaha amplifier you see under the RPi player (3). It has got 11 extra buttons. Apart from the usual play, pause, next and previous buttons, I have 6 buttons on the remote that are mapped to several playlists.
You can use any IR remote to control your player. All you need is a 10Euro IR receiver and a python script. I find it a must to be able to operate my player with an IR remote.
I recently added an arduino (8) so that I can use the IR remote to switch on the player. The arduino is permanently on and ready to receive the signal from the IR remote, in which case it activate a relay that turn on the atx-type switch (6).
The IR remote ''on'' button switches on both the player and the amplifier at the same time, and the IR remote ''off'' button (different from the on button) switches off the player and the amplifier at the same time. That's cool.
On the second picture you can see that I use a linear power supply (9 and 7) to supply power to the allo boss sound card (11) and a 2 amps switching power supply for the RPi (hidden on the picture). The vu-meter driver (10) has got a separate 12volts power supply (hidden on the picture). The arduino has a different 5volts power supply.
For me, the priority is the ease of use. I don't know if all those addidtions have an impact on the sound quality. I am sure an 'áudiophile'' will tell you it have an impact. It does not matter for me since i am not an audiophile.
