Best amp with bass boost under 150$?

[sloomingbla]

Right now i have the fiio e11 and i just cant take how much the bass boost effects the quality of the music, even when its on the 2nd option.
 
Any suggestions?
 
I'm going to use this with an iphone and a pair of ultrasone hfi 580's by the way.

In order of my preferences (that I have heard):
 
Headstage Arrow 3G (Used)
FiiO E12
JDS Labs C421
C&C BH - Although not a pure "bass boost"
 
All have good bass boosts, although the Arrow has very good bass boost. Quite clean, especially on setting 1.

Oh wow, thanks alot. Yeah i've been doing alot of research and the fiio e12 looks like it's got a really nice sound sig and the bass boost is almost just sub bass, which is nice.
 
Although i might have to check out the headstage one too

Oh yeah, and the cheapest model i could find used of the 1st one was like 200$, i just cant afford it right now. but atleast i know what im gonna upgrade to next
