QED is an American company founded in 1973 and specializing in the manufacture of the highest quality cables. QED is an abbreviation (Q.E.D. - quod erat demonstrandum) from English which translates as what was required to prove. In 1994, the company initiated a large-scale study on the effect of cable quality on sound, the results for many were shocking. Hi-FI / HI-END manufacturers in their products try to reduce signal loss to a minimum so that the end user can enjoy the high-end sound of their product. And in the end, the consumer takes an old cable, bought in the nearest store, and DOES NOT get a surge of emotions and admiration from listening. QED solves this problem.

QED is a leader in its segment and this is achieved thanks to several factors.

1. Technologies - the company always strives to improve its products and follows emerging trends in the market;

2. Warranty - when buying any product of the company, the consumer receives a lifetime warranty;

3. Reputation - a company has been on the market for more than 40 years and has one of the best (if not the best) reputation in the field.

4. Result - the consumer will always get the best possible result, this is confirmed by the numerous awards of the company in the field of Hi-Fi.

If you need a better solution for connecting anything, the choice will be obvious to QED - as required.
