Hi I have a factory fitted head unit in my BMW X1 2019 connected to focal speakers in 4 doors, under seat focal woofers and match pp86 dsp amplifier. I also have dd sub woofer powered by a separate amplifier. My car doesnt have aux input and has usb inputs regular one and type c. I play music using tidal premium service on iPhone. Tidal premium service offers MQA files. My system sounds great but I want to make it sound better. I’m considering 3 actions and want i outs from audiophiles
1. Installing a hd usb sound card to match amplifier so I can directly connect to USB input of amplifier and bypass the factory fitted receiver.
2. Buying a new portable player which can stream tidal MQA files and other high quality files. I have heard that iphone is not certified for MQA.
3. Alternatively attach a portable dac to iPhone and then connect to usb c of headset
Do you recommend both the above or some other alternative?
