I had a good listen to most of the expensive Louis Eichmann interconnect cables at the get together, and at the same time returned my loan set to check if they had any problems, and indeed they sure did, they just did not sound right here, and on hearing them Keith Eichmann feels they are faulty. The interesting thing about Keith's interconnect cables is they have a sound, lets call it the Eichmann sound. The different models do have a house sound, and the unique ability to make average systems shine, they are a cable that will please, and very few will be disappointed. I must say they have a lot to like particularly warmth, liquidity, blackness, and the lack of grain that helps to promote a very low noise floor, the latter in particular is what sets them apart from others, how it manages this is open for debate.
