Fanatical and prejudicial Bose hater here.

You can say what you want about them, but in all fairness the tuning they do for Porsche is actually really good. The Burmeister option that costs five times a much only sounds marginally better than the Bose option.

Even factoring in the engine noise you’ll get on most models coming from behind you, they tune it pretty well for their cabins.

If by DAC you’re talking about ultimately using the analogue out on it, I wouldn’t do that with any computer.

I use Airplay for anything 16-bit. If I wanna go fancy 24-bit 96 KHz, I use a media server to my amp.
