3 speaker cable options - what to choose?


Hi guys,
First of all, I new here, it's my first post, nice to meet you all.
Now to business:
I am looking to upgrade my current speaker cables (VDH cs-122)to something much better.
I have narrowed down my choices to 3 options:
1. Audio Art sc-5(se)
2. Morrow Audio sp-5
3. Clear Day Shotgun
My budget is $250-$350 and all three fall within this price range (either new or used), the ClearDay is a bit cheaper than the other 2, but the double shotgun version is out of my price range.
My speakers are 88db, 8ohms yet quite power hungry.

Which option will give me the best sound?
Any advice, especially from someone who's had a chance to here more than one of them, would be highly appreciated.

Thanks

Why do you want to change your cables...what improvements are you looking for?? If there is a wart in your system, fix the wart rather than find a cable that will hide it. Unless you listen to the new cable in YOUR system you will never know what improvements or deterioration you can expect. One cable may be fine in one system and awful in another.
This thread's going nowhere, just tell him what he wants to hear. Buy the Clear Day Double Shotgun, it's a great cable, you will love it. ;)
Jmcgrogan - Yup, that's the spirit, everything's much clearer now - just what I was looking for. thanks for the tip. (regardless of the fact that my setup sounded much much better when I hooked up a pair of Gabriel Gold Revelations I borrowed from a friend, an experiment that taught me that speaker cables CAN make a difference, and that my electronics are fine, a bit lacking in power but nonetheless willing and able. But hey, I've already made up my mind, right?).
Buy what ever is the piece Transparent Audio makes at your price. There is a reason people buy them. Buy an entry level Mercedes rather than a Kia. Also consider power conditioning! It is not snake oil.
