Audiophile Setup with an Iphone 7


Dear 

Could anybody suggest an Amp + DAC audiophile setup for an Iphone 7. Top Quality.

Many thanks !

Use a mini jack to stereo RCA adaptor and just get your favorite headphone amplifier with a volume control. The internal DAC in the phone is pretty decent.
Rpeebles, what's your budget?  Also, do you intend to output the Tidal service via your iPhone?
