Ubuntu system wide PulseAudio EQ (Equalizer)

I have recently become much more excited about cleaning up my music library within Ubuntu (versus just using WinXP and iTunes) so I can eventually get rid of Windows once and for all. (iPhone user - iTunes dependent currently) The audio levels that came from the default sound card in my machine were just not adequate for how I wanted the sound system to sound from my 2.1 Logitech system.
Built in Sound Card specs per

sudo lspci -v

Off I went in search of an EQ application or addon to PulseAudio sound server system that was both easy to install and "just worked". I had come across a very interesting search result which was to enable a Personal Package Archive (PPA). Some Ubuntu users question the use of PPA's as they "can" pose a security risk but that's not what this post is about. I enabled the PPA and sure enough, "it just worked" and now I am able to click a preset such that the audio levels of various Hz and KHz ranges are affected and my audio files can be played back more accurately for those high highs and those low lows.
