whats the very best sounding cables for realistic money


hi,
can you all please tell me if there are a really special sounding cable out there for realistic money, ie power cables 300/400gbp, signal cables 1m 400/500gbp and speaker cables for around 600/700gbp, i know its still alot of money but there must be a manufacturer out there thats not pulling our trousers down, or spending time and money on R&D to solve problems that do not need addressing ie over the top shielding or some other marketing nonsense, the company i am showing interest in are Anti cables ??????????

@jriggy  Thanks. I will pm you for more info. Do not want to wander off, for the thread's sake.
Wireworld cables are very good. Replaced my Anti Cables in a Jolida 1701 Magnepan MMG setup. Arcam rDAC. More info and less harsh. Their USB cable no better than Walmart cable. Upgrading USB is a waste.
Expensive cables fix fabricated problems.  Even cable manufactures do not and cannot scientifically explain what their cables are designed to do.  They make over designed, visually attractive cables that perform no audio or acoustic function beyond that provided by inexpensive wire of the appropriate impedance and length.  Nothing new here.
