After messing about with different components for years and years and also having quite a negative viewpoint on overpriced interconnects and other snake oil hifi bits I have now changed my mind and decided that the best money I have ever spent is on 2 x 5metre lengths of chord signature speaker cable. These are outstanding, especially during low volume late night listening sessions where without the power from the amplifier the detail and stereo image is still amazing, god forbid I get a shot of nordost valhalla or odin. So what I want to know is what product has transformed your listening experiance and why?
