A Behringer Studio Monitor was the 1^st loudspeaker which awaked the KEL 84 to life. With this low cost model the small amplifier could perfectly show its vocal presence and the reproduction of small details. When the amplifiers showed that it ran without problems also on high levels it was attached to my Tannoy Edinburgh. This was a revelation, particularly for the price segment in which this amplifier is situated. This is a real alternative to lots of transistor amplifiers!

The “Live End Hifi Studio” in Muelheim gave me the possibility to an ultimative, perhaps not completely fair test with a Tannoy Kingdom. This loudspeaker shows all errors the equipment can make. I have heard many expensive High End systems which were all about appearances! The Tannoy Kingdom is a four way system with Supertweeter and an efficiency of 91dB. These loudspeakers are very rarely on the European market. So far I know this is the last couple which can be bought as demo system in Germany.

First of all we attached another model which is from the company JMlab. This is a small, however, fine loudspeaker for racks which was available from a customer order at that time. Source for all tests was the CD Player of the British company HHB.   

Together with the JMlab loudspeaker the full amplifier presented a full sound plentiful of bass and little details were still audible. After one hour, during which we heard lots of different music styles we changed to the Tannoy Kingdom. The high efficiency showed that the full amplifier is absolutely quiet in an open-circuit operation. That is not naturally for a tube! Then the first songs of Sophie Zelemani and the acoustic guitar of Badi Assad were impressing! The full amplifier drew a spatialness and a detail wealth which is absolutely incredible! This proves that one can get lots of Hifi for a low budget. Amazing!

Here the company World audio Design developed a brilliant equipment! We hope that further will follow, perhaps an output stage kit with the 845!?
