MacBook Pro>Fiio E7>D5000
MacBook Pro>old Pioneer receiver>HD 598
What would you guys recommend using to amp the D5000s and HD 598s? I particularly like the bass boost on the Fiio E7 for the D5000s and sometimes HD 598s. I really don't know a thing about amps so I am open to suggestions. Trying to stay under $400 but would really like the cheapest option.
