For me, pre Decware, I biwired my speakers. With Decware I have single driver speakers so it isn't an option. With low power amps and high sensitivity speakers I feel like the advantages of biwiring are reduced, but not eliminated. What isn't reduced is the impact of the speaker cables on sound. So if you have speaker cables you like, and they are biwire, then by all means stick with it. But if you are looking to up your wire game then I would rather spend the money on a better single run then on biwiring. JMO/YMMV and all that.
