KR Audio - Vacuum tubes made in the Czech Republic

This beautiful images show the manufacture of Vacuum Tubes in a small company based at Prague, in the Czech Republic. Each tube is more like a piece of art and is used in high end audio amplifiers to give amazing sound reproduction. To young people who were born without knowing vinyl records and are used to modern MP3, it might seem strange that music and sound can have much more to give, but it is indeed the case. Specially the emotion that a music composition or a voice can deliver through a Vacuum Tube amplifier.
