In an interview with HIFI World,he claims he designed a switching box to demonstrate his cables.One flick of a switch and the music switched between the free cable and his own.He went on to say the buyer public were easy to convince becuase they believed their own ears,he even claims that changing cables could have as big effect as changing amps. So why don't dealers nowadays use a similar device so their customers can hear differences between 2 cables? is it because many years ago,the difference between the cable that was built in the speakers were so bad it was easy to make something better.............but acccepting that arguement means you accept that cables do make a difference,its just harder to hear now because you don't compare bell wire with £500 high end stuff anyway,just thinking out loud,anyone want to build a switching box?
