DO NOT CONNECT THE OUTPUT OF A HEADPHONE AMP TO THE INPUT OF YOUR POWERED SPEAKERS!!!!!!!
Use the mixers pre fader aux sends to go to the headphone amp. Here you want to use shielded cabling. If both mixer out and headphone input are balanced connections, then you want to use balanced cabling. If they are not BOTH balanced, then unbalanced cabling is what you use.
Use the mixers control room or main out to go to the speakers. Again you want to use shielded cabling, and if both mixer out and headphone input are balanced connections, then you want to use balanced cabling. If they are not BOTH balanced, then unbalanced cabling is what you use.
Belden, Mogami, Canare are all great cabling. Belden is usually the least costly, and works great.
Neutrik connections are excellent, simple to assemble, and lest costly than Switchcraft.
All line and mic level connections use shielded cabling. Only amplifier outputs use unshielded cabling. There is no such thing as balanced speaker cables. Speaker cables have 2 conductors, a +(plus) and a -(negative), there is no shield. You're confusing the headphone amps output, which is for headphones, and is a left, right and common neutral.
Again, DO NOT CONNECT YOUR KRK POWERED MONITORS TO YOUR HEADPHONE AMP UNLESS YOU REALLY DON'T LIKE YOUR KRK'S, THEY WON'T LIKE BEING CONNECTED THIS WAY.
Best of luck.

I need to make a ton of 1/4 cables and a few XLR, and its all conecting my DIGI 001 my keyboar, my MPC, and my speakers/sub together. If you need more info on my equipment feel free to ask.
The 001 uses both balanced and unbalanced connections, depending on which i/o. Check the Digidesign site if they still have info up on the 001. However in all cases connections i/o of the 001 want ot be shielded cabling. All inputs (XLR and TRS) are balanced, and as I recall, the 8 TRS outputs are balanced, but the monitor outs are not. However best to check the specs beforehand.
Remember, if you are connecting an unbalanced input or output, the circuit is unbalanced, regardless of what the other end connects to. Don't waste money on balanced cables when you're connecting to unbalanced i/o's. Also, when using unbalanced cabling, stay far away from AC and expecially transformers and CRT's, and keep the length under 15'.

what I meant by this was the pair go from the mixer to the headphone amp and "from [the headphone amp], a pair of cables go to my KRK RP8 monitors."
does that make sense? there are inputs and outputs on the headphone amp so i run the monitors out of the "monitor outs" on the headphone amp.
Just be careful that those "monitor outs" are not amplified outs from the headphone amp...since your KRKs are self-powered...they need a line-level signal. Most people go from the mixer to the monitors...using the provided Control Room A/B outputs...or some other output intended for feeding control room monitors. But...maybe your headphone amp also has a line-level output that goes directly from its input....??? Just check before you plug in and turn on.
For the record, I have a cheapy little Samson 4-bank headphone amp that has a "pass-through" in the back, unamplified. It's not that uncommon a feature.

DdubBdrum, if you could give us specifics as to what gear you are connecting, we can give you more specifics as to what cabling you should be using.

Not looking to stop the positive, helpfull replies...
...but the OP posted this back in April...and I haven't seen him back here since with any follow-up questions.
So all these good suggestions may be falling on deaf ears at this point....and I'm kinda' thinking he musta' worked out his issues in the last 4-5 months!
