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

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.

He's right. There's a reason some of us are not sure that you are doing the right thing by getting your cables before electronics. I can only speak for myself, but I think its foolish. You can get lucky, but the reality is that the same pair of cables can sound different from one piece of equipment to the next. The Gabriel Gold Revelations that you tried with your current amp may sound bad on the next one. Just to be clear, I'm not saying they will definitely sound bad, but it is a real possibility. That's just the way it goes with audio equipment. Also, I speak from actual experience. I've made this mistake myself (and plenty of others, too).

A top KIA is a LOT better than an entry Benz."

Spot on as always, Schubert.
