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

Electronics will be replaced later this year, not now. This a different scale of budget we're talking about. Currently I want to finalize the SC upgrade."

I don't think I get what you are trying to do. How can you finalize your speaker cable upgrade before you have your new electronics in place?
Zd542 - I want to enjoy my music today, not just a year from now, that's why I want a pair of cables I won't have to upgrade a year from now.
Leaning towards the Clear day double shotgun despite the price
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?).
