audioquest gibralter speaker cables

I have vandersteen audio 5A speakers and a modded denon 3910 dvd player. I have them biwired with audioquest bedrock speaker cables. I would think that getting a pair of audioquest gibralter double biwire cables would be a nice upgrade, but I have read some reviews that said the gibralters were a little on the warm side. I have the dvd player hooked up to a lessloss power cord and that took a lot of harshness out of my system, do you guys think that the gibralter cables would be to warm or would it be a good match, I would audition them but that is not an option. I would appreciate any comments of those with experience with this cable, thanks
