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 ??????????

SignalCable. Expertly hand-assembled, sensible proven designs, reasonably priced (buy direct), great customer service. What more do you need?
@david_ten, I have some Seven+, an older Eight+ or two I'd like to upgrade at some point and a Digital American. would also like to try a High Power for the amp, which might have a bit deeper bass over the Seven+ but they are close in performance to each other, from what I've read. 
Lowes hardware store,  this is good cable for realistic money!, get the 10awg speaker's cable's 😂🤣😃
@jriggy  Thanks. I will pm you for more info. Do not want to wander off, for the thread's sake.
