Connecting
- USB-C iPhones (iPhone 15 and later) take a USB-C DAC or dongle directly.
- Lightning iPhones need a Lightning DAC, or Apple’s Lightning to USB 3 Camera Adapter with a USB DAC. The adapter with a power input helps with DACs that draw more current than the phone likes to give.
- Class-compliant USB audio devices need no driver on iOS. If the phone shows a warning that the accessory needs too much power, use a powered hub or adapter.
Getting the right sample rate
An app can request a preferred audio-session sample rate; iOS and the connected route determine the actual result. In MP95, use Match output sample rate where available, then compare the source rate, actual output and any DAC display. Support depends on the DAC, connection and current audio session.
A request for 96 kHz is not evidence that every device accepted it.
Keeping the path clean
A lossless source describes the recording, not the whole output chain. For unprocessed playback, disable effects, EQ, ReplayGain, crossfeed and headphone correction. Check the actual output rate as well as the source rate. A matching rate alone does not prove bit-for-bit delivery through the operating system, volume control and output device.
A note on dongles
Some small dongles only accept 48 kHz, or 44.1 and 48. If the Output line shows → 48 kHz · resampled for a 96 kHz file, that is the device refusing the rate, not the app. Check the DAC’s specifications.
Formats
MP95 supports FLAC, ALAC, WAV, AIFF and other listed formats, plus DSF and DFF through conversion to PCM. DSD playback is not a promise of native DSD or DoP transport. Check the actual decoded and output rates for the file and version in use. See supported formats.
Frequently asked questions
Does the iPhone support 24-bit/192 kHz?
Through a USB DAC that accepts it, yes. Not through the built-in speaker or Bluetooth.
Do I need Apple Music Lossless for a DAC?
No subscription is needed to play your own supported files through a compatible wired route in MP95. Connection, power and DAC compatibility still need to be checked.
