I found the solution! Hi Res portable player from Astell and Kern (AK-240). Conversion cable from Aux out on the player to Aux in on my processor. All parts on order. Will review the setup when I get it all set up this weekend.
Has anything else not reached your ears? None of that will make a big difference as a proper install. Speakers thrown in a door with big holes and gaps have minimal chance of it performing properly, in fact most sound like utter garbage in a sub-par install. Car audio is not like home audio where you just throw stuff together and have a good source and be done with it.
-Home audio has a wall socket for almost unlimited power
-Car audio has a 12 volt charging system which directly impacts the performance of your amps.
-home audio has very minimal noise, sound proofing is rather simple with some acoustical foam.
-car audio, ANYTHING can be an unwanted reflection causing phase issues and blocked sound EVEN your legs, chairs and the materials of your car will have a big impact.
-Home audio speakers are in a nice sealed cabinet so getting proper sound out of them is almost a no brainer
-car audio doors are horrible resonating flimsy sheets of metal along with a plastic panel where sound can get trapped and all sense of sound quality is out the door.
I'd highly suggest you find a nice Real time analyzer to tune your DSP properly or have someone that really knows what their doing on a serious competition level install/tune level or else you'll be wasting your gear away.
THIS is a REAL install take your time and actually look through what is needed to be done to even tap into any potential of what your speakers can actually do rather than stressing over lossless vs 320kbps which Is utterly useless in real world performance wise.

everything else i mention will get you sounding 95% better. lossless instead of 320kbps 3% improvement tops. Totally focusing time and resources on the wrong aspects here.
