So I have a question for all you otakus. It is a bit unrelated, but most of this thread seems unrelated, so hopefully it'll blend right in. I wanted to buy a portable headphone amp for my portable music setup, but I have an iPhone 5 as my DAP and unfortunately the Lightning port makes compatibility a bitch. I don't want to buy a DAC on top of an amp, and apparently a lot of the DACs aren't compatible with iOS 7 in any case.
My question is this: Would connecting the amp via the headphone jack of my iPhone 5 completely destroy the sound quality of whatever amp I get? I mean, I understand that it won't be as good as bypassing the iPhone's internal amp, but will amping an amped signal really screw everything up?
I've read through the forums somewhat, and I am getting a lot of differing opinions. Some people are saying "never do that, it will destroy the world," and others are saying "it'll still sound much better than straight from the DAP." I figured that it might be better to ask in person, and you lot seemed like the right bunch.
Thanks ahead of time! I appreciate it.
