I am getting a pair of Sennheiser HD 598s soon,and I am deciding which amp to buy.
My current options:
Fiio e6 (great because its small!)
Digizoid ZO 2 (bass boost)
My main goal is to increase the bass on the headphones. The Digizoid seems good, although i hear it lets the bass get out of hand, while the fiio e11 keeps the bass tighter and more controlled
so i was wondering, which would you use for the 598s to increase bass and still keep it clear
