Digi 003 Vocal Quality Issue

[ThaPath]

So I've had my 003 for a couple months now and still can't seem to figure out why the vocals have a slight distortion when I play back what I recorded. I'm running Pro-Tools 8.0.4 LE on a HP H8-1120 [Windows 7 Home Premium - 64 Bit]. I use a AT4060 for a recording mic, which runs through an Avalon 737 pre-amp, then through a TC-Helicon Voice Live Touch Effect Mixer and finally links into my 003. At first I thought it was just my mix, but then I recorded through Adobe Audition using the TC-Helicon as the vocal capturing device and the quality is much nicer even though I was using the same mixing process. Then I was thinking that maybe the phantom power is on, on my 003, but the "Setup Guide" it comes with doesn't make it clear if the phantom power is on when the button on the back is pushed in or sticking out? Either way I'm not sure if that would alter the quality in any way but I'm just running out of ideas on to why it might be sounding like this. My microphone has it's own powering unit, so I don't need to use phantom power. I would assume it's not great to have two mic power sources on at once though.

I would just use Audition, but I feel as if I can achieve a much better sound through Pro-Tools if I fix my problem and I definitely wouldn't want all the money I had my sponsor spend on my studio go to waste.

I've been making music for 2 years and I'm only 17, but I'm very new to all this high end equipment work so excuse me if I come off as uneducated with this type of stuff.

Here is a preview of how my vocals sound in pro-tools.
You can skip into about 0:45 to get right to the vocals.
These are the best vocals I ever got out of pro-tools.
Usually there is a bit more of a distortion, but this one is just kinda rough around the edges.

Now here is something I recorded in Audition.
You can skip to about 0:15 to get right to the vocals.
These vocals are much more present and not so rough.

You might not be able to tell too much of a difference on regular speakers at low volumes, but I'm pretty sure if you listen with headphones or mixing monitors you'll instantly be able to tell.

Thanks in advanced to whoever can help me with my problem!

make sure you gain staging from the preamp to the effects to the 003 is balanced.

When you feed the TC unit into the 003, you should be using one of the LINE inputs(5 thru 8) with a TRS cable. If you are going into an XLR input, you are double-preamping, which can't be a good thing. Personally, I would record straight in(mic>power supply>003 mic input) and see if that sounds clean. Then you can route a send out a line output, process thru the TC and record that sound to a new audio track. Then, using the original as a guide, nudge the new track into perfect alignment. Then you can mix/blend the 2, or just mute the original dry track.
