So I have a pair of Shure SE315 that I love... Trouble is they lack Bass unless boosted properly - what I mean is they are super flat when plugged into a generic source like my laptop where when plugged into my sansa with proper EQ the bass comes alive and is rather impressive while maintaining the highs and mids that the 315s are known for.
Recently at a head-fi meetup in the Philadelphia area (oct 26) I had the opportunity to try my headphones with some portable amps and not so portable Tube amps. I noticed a difference in the "aliveness" of all the frequencies/bands/ect .... (basically it sounded nice. I wanna do now)
So I was looking at various diy headphone amps and Ive been wanting to learn all the electrical stuff for awhile now... I wanted to make a 3 opamp design ... a left, right, and bass channel. Each channel having its own op amp... The bass channel would be sourced from the pre-opamp left and right -> mixed together -> apply low pas filter -> amp -> mix back out into the post-opamp... Put it all in a neat little container... Maybe some modular boards using 8pin headers and pcbs for each channel / mix.
I thought of this idea while using my sound board - Id create channels for specific frequencies and route them to appreciate speakers/amps.
Is this a waste of time? Am I over doing it? Am I plain wrong? I was thinking of using these op amps. http://www.ebay.com/itm/261269062286?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1438.l2649
