I have a really old Aune T1 DAC/Amp. And I recall that when I first got it, it could drive very low resistance IEMs just fine. But after all these years, all at sudden, it can't anymore. It can drive planars such as my Sundara.
The specific problems it has with IEMs now are:
1) Overall, volume is tiny.
2) No base and mid is thin. Everything sounds like far away.
3) If I really increase the volume, a lot of distortions and pops kick in.
So it feels like the output resistance is just too big now. And planars are less affected, but IEMs are just not able to get decent power anymore. I am just curious if this is common and if so, can I salvage it?
