best biwire speaker cables for under $300??

I owned Analysis Plus Oval 9. Great speaker cable. I agree with Jylee that single runs with jumpers sometimes works better than bi-wire. This is what I found when I replaced the Analsis Plus bi-wire with a single run of Straley Reality cable with Straley jumpers (I also auditioned Straley bi-wire). The Straley Realty Cable sounded more transparent and had better bass control than the Oval 9.

Your mileage will vary, which is why buying used wire, or buying wire with a money back guarantee reduces the risk.

Alpha Core Goeartz MI2 Veracity (whew) excellent cable with beautiful tone and very open

I'm running a pair of Audioquest Bedrock bi-wires with AQ spaid terminations. I'm not sure if you can classify them as warm, as I've had to gear everything else in my system to the warm side (golden reference ICs, Musical Fidelity A5 integrated). I may have inadvertantly geared my system around these cables due to their brightness, but either case I've no real complaints about them. Very revealing with great low end response.

Both anti-cables and alpha core Goertz MI2s are great with all the Vandersteens I have heard. I prefer them to audioquest mont blanc cables that are much more expensive.

Thanks for the responses! I actually have anti-cables that I tried in a biwire configuration with my Vandys and they did improve bass response somewhat, but the highs were rolled off noticeably and decay on notes seemed to be missing. I've tried to burn them in (100+ hrs?)but they still sound compressed and rolled off compared to my other DIY cables. Do they need more burn in time? Again, suggestions regarding the ACs or other recommendations is greatly appreciated! And to you all who recommended the Reality cables, I did some research and am greatly intrigued. May need to start saving my pennies...
