Hello everyone,
 
I'm new to this site and new to headphones and audio equipment in general.  I picked up the B&O's to use with my iphone/ipad/macbook, and while I enjoyed their realistic sound, they lacked much in the low end.  So I recently got a pair of P5's, and while I love the sound overall, I feel like I'm losing a lot of juice using it without an amp.  In addition, I would probably use the improve the sound on my portable iHome speakers when needed.
 
Amps under $150 is where I would like to start, and upgrade later if I need to.  Thanks in advance for your comments!

this might have been tackled elsewhere but I wonder if the P5s would benefit from a portable amp coupled with an iphone, as they are marketed as low-impedence and ready for mobile use.
