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?
