just the beginner...
 
have one Superlux hd681(for recording vocal) and one Sennheiser hd558(for listen pop music).
 
onen yahanma audiogram 3 for my recording interface and DAC
 
I always listen pop music..and like strong  and low bass, warm sound quality..
 
(1) my source gear is Sandisk Sansa e250....what else can I buy in order to make the sound more powerful or sound better if I connect it to hd681 and hd558..
 
(2)when I use NB for my source gear, and connect to audiogram3 for DAC...then connect to hd681..
why the sound not good as what I imagine...
for the different situation:
Do I need to change other DAC? headphone amp?? source gear? cable?? or something else?

I think you should try the Fiio E10, haven't heard the Audiogram so can't comment on that!
