Hi all Head Fiers friends
i want to share my personal experience with my friends , that the charger for the battery our portable Dac and Amp is very important .
we have tried many different charger to charge the battery from our audio gear , especially
5 volt with micro or mini USB charger .
for example : go dap dd1
Hisound studio v 3rd edition ,
Astell and Kern AK 100
if we charge with iPhone charger has different sound quality compare with blackberry charger or external power bank like Energizer xp 8000
i will share our opinion with many charger for the best sound quality as follow :
1. We use Energizer xp 8000 power bank
2. We use blackberry charger from old type / bigger size
3. We use Iphone charger
please share your opinion and experiment here
