This special sound characteristic can only be found on Valvo Hamburg tubes. And because of the added substance in sound, the overall tonality of these tubes feels sweet, warm and musical, and the ambient clues sound closer to your ears. One may find Telefunken's midrange thinner compared to Valvo Hamburg as a trade-off of a more enveloping and curvier holographical sound stage...the law of physics applies here as well - the shape of sound can only change in one direction. \u003cbr\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"font-family: Arial;
