I have the IPHONE 7+ and DFR. Amp wise,Do the 99s sound noticeably better using a Dragonfly Red, as opposed to not when playing music from an iPhone 8?
not to big of a difference when compared to using the dongle. But the DAC is pretty good and worth it. I like the combo a lot and it sounds better then straight from the phone even though it has the juice to power them. The 99’s are so easy to drive.
