I use for travel heir 4ai and jh16
Both sound horrible on the iphone 5
On other amps/ dacs they sound great
I'm not sure why
I just purchased an dap x
All sounds fantastic with it.
Ps one last item I also,own a tg334 and that sounds good on the iphone 5
Of course it's better on other amps but why do the others sound so bad
Ps at low sound level half or less its still distorted.
Any insite would be appreciated
