At least the iPhone's DACs are absolutely audiophile quality, especially because the idea that "an audiophile quality DAC costs 20x what you see in smartphones" is patently ridiculous. There's no evidence at all that any good as in not flawed DAC will sound the same on nearly any, if not any system. At the very least, the audio quality degradation of most bluetooth devices has a worse impact than even your average middle tier Android phone's dac.
