Equalization for my set up


I have a Peachtree Audio Decco65 pushing a pair or Paradigm Monitor 9s. Mostly I play iPad Beatsmusic subscription app thru Apple TV into the Optical input of the Decco. Sometimes I play CDs or iTunes or other internet radio. I love the clarity and utterly clean audio especially Beats. My only minor issue I'd like to add just a tad of low end. I'd like to avoid adding a sub if possible I prefer the true stereo experience.
iTunes has an EQ and I have "boom" on my laptop when using the USB. Boom sounds really bad. And I prefer the higher bit rate audio on Beats than iTunes. None of the EQ Apps on iPad function when streaming to Apple TV.
My questions-
Does anyone know of an EQ app that will work when streaming Beats and while Apple TV is activated?
Or since the Peachtree is an integrated I know I can't add an external EQ. Although if I knew someone who could customize an 'insert' to put an nice analog EQ "in line". Anyone do that level of component work?

Just looking for a few db more of Low end around 30 to 40 hz. Open to ideas.

I'm with the guys. Adding a sub is the most logical thing to
do. Sometimes EQ doesn't fix certain issues.
Thanks for your input guys. Just to clarify. I love the clarity of my set up and on many tracks, especially newer recordings there is plenty of bass as is. I'm not a fan of iTunes because the files are so compressed. And when I've tried the EQ on it it just makes the files sound over all less clear.
I'm just looking to add a few DB from time to time depending on the track. Like adding a pinch of salt :).

Something's not right. If you just use a small amount of EQ in iTunes, you shouldn't loose clarity. I haven't used iTunes in a while, but most EQ's in music player software have an overall gain control, as well as the individual eq frequencies. For best sound when using a PC, you are supposed to have your volume on the player software and your OS set to maximum. But not the one on the EQ. That should stay neutral or 0 gain. Its usually half way up on the slider. With too much gain, you may start to break up kind of like when have too much gain on a phono cart.

Aside from that, try ripping some of the problem albums to wav and see how it sounds. iTunes will play wav.

If that doesn't work, try a different music player. You don't list your OS, so here's a list of free players that work with Windows, Mac and Linux. Amarok, Clementine, Audacious, Banshee and Quod Libet.

If you try the stuff I mention above, there's a good chance you'll be able to fix your problem without having to buy anything.
Sorry, I didn't notice you were talking about only 30-40 Hz. I was going to say check out a variable loudness control (see: http://alumlabs.weebly.com/). Much simpler to operate than a parmetric EQ. But a variable loudness control will increase the treble along with the bass, which might not be a good thing for you.
