Get yourself some Mark Grants, none of this 'Monster' and QED crap.
And now that Mark Grant has his new interconnect range which are £75/m is he now perceived as a rip off artist and con-man whereas previously considered a fair and honest cable maker with good value products?
He would be one of the first guys to swear black and blue that cables of all types *can* make a difference under the right conditions (interconnects/speaker/mains). Basically anyone in the industry worth their salt knows this to be true.
It's true that there are a few of companies out there releasing crap products with huge markups though, ***cough*** QED/Monster but that's true of any industry.
