Well, it might be an issue if you try to drive non-sensitive headphones, e.g. planars with your W2 on 85++ volume in High Gain: you still can do that on Android but not on iPhone, I faced that while trying Aeon 2 Closed. Anyway, it's not a good idea to max out volume on HG but still expect good sound quality, so it shouldn't be a big deal.No issues unless you run very sensitive IEMs like Andromeda and turn volume so loud that your grandmother will complain and you want to destroy your ear drum - so in short: distortion is rather a theoretical case than a practical one with IPhone
