Hello im new here and own a pair oh Sennheiser hd 280 pros. I thought i wanted to upgrade to the hd 555 or 595's but did not want to spend quite that much now for headphones. So I did a lil research and found out to get a louder, better sound an amp might be in store so im here asking, what amp might be good for the 280's that give them clearer louder sound at a good price? Also if this help my primary use with my phones is an mp3 player and occasional use on a home stereo. Also what are other headphones to compare to the 555 or 595 that are from a different manufacturer? Or is it just best to stick with sennheiser? Thank you
