Hi all Head Fiers friends

5 volt with micro or mini USB charger .

                       Hisound studio v 3rd edition , 

                       Astell and Kern AK 100

Yes it is , the blackberry old big charger can make better SQ than new blackberry charger

This is going to be like that "Fuse's that sound different" thread... 

The best way if you connect directly your power outlet with separate fuse in your electrical panel , and you can try it in your power outlet between the first , second and the other plug 

and you can hear the SQ different .

Hi Penmarker 

for all my 5 volt portable set up I have tested with many charger , like IPod charger , blackberry old / big charger , and many portable power bank .

i have tested on my dap AK 100 and Hisound studio v 3rd edition

The result are different between all the charger that I used 

Note :

you can try like me , please connect your power bank from different brand to your dap like in my picture AK 100  during you charger , and play 1 song , and stop the song , take out the charger A and directly change with charger B and the other charger as well .

you can hear the SQ different very clear .

if you find the best ones , you can use as your reference charger for your audio gear.

until now my best charger is Blackberry old charger 

for power bank is my Energizer XP 8000 

p

^^ thank you Penmarker for  your explanation .

My explanation above only to test sound different from many power bank , the result IMO if I use power bank Energizer to charge my AK 100 is the best compare the rest from my pier bank .

For he theory I don't know why so different SQ  with different power charger and power bank .

maybe another members can help me for the explanation why the SQ so different if I use different charger or power bank ?

thank you
