I am going to have to go with Philojet and the Gabriel Gold recommendation...I would keep an eye out for a used pair of Rev II's...or talk to Steve about the new entry level Radiance. You would get what you're looking for. I went down a long list of cables in that range and much higher and replaced them early on with Gabriel Gold Extreme's I still use the GG's....but now the Reflections. They are a whole different ball game and absolutely astounding, but beyond your range. Stretching as far as you can up the GG line for you IC's would be a good option.
That said, I yam what I yam and have had a lot of cables, and I thought the Analysis Plus Solo Crystal offers a lot of bang for the buck. Their Oval 9's are also good.....but best bang for buck went the Bear Labs Silver Thunder. And, if you can strecth a tiny bit, Stealth Hybrid MLT's are hard to beat at around 1k.
I have the GG's Rapture r and the sonic improvement over the non-revised version coupled with the Reflections just breathes life's musical essence into my intracellular spaces....happhappyjoyjoy.
Enjoy the tunes!
