For some budget type speaker cables that are crisp & detail I would recommend The Worlds Best cable 9 gauge premium versions. They are very flexible for their gauge size & look beautiful in their wrap with nice connectors. I paid a little over $200 for them.
I found them to be extremely lively. Too much for me personally but if you have a dark system & wanted to open it up I would recommend to give these a try. At the time I tried them I was wanting to replace a pair of Rocket 44's. The WBC really showed off how soft & laid back the AQ's were. I eventually just went back to a pair of copper cables I bought from Japan in the 90's & put new connectors on them. They just have a plain rubber type jacket with koetsu stamped in a couple spots..but he was a TT dealer.
Those Worlds Best come with a life time return policy lol. I returned them after a couple months no issues.
