Dette er den beste rørforsterker vi kjenner til under kr 100.000,-!
Audio Valve er et meget eksklusivt merke, for de som vil ha et alternativ til de aller beste amerikanske merkene.
Assistent 100 kan være et alternativ for deg som har vurdert å en effektforsterker med rør, til over kr 50.000,- samt en forforsterker på samme kvalitetsnivå. Skal du kjøpe en "pre/power" kombinasjon på dette nivået, vil du også trenge en relativt dyr siganlkabel for å oppnå den lydkvaliteten du søker. Da har du kanskje allerede passert kr 100.000,-
Skal du investere i en effektforsterker som bruker samme rørtype som Assistent 100, nemlig 6C33, vil bare den koste rundt kr 100.000,-
Selv om du da velger en av de beste amerikanske merkene, vil teknologien være mer primitiv enn på Assistent 100, så du vil ikke få en like god ytelse på rørene.
For at du skal få litt kjennskap til hvor langt fremme Audio Valve ligger på ny teknologi anvent på denne rørforsterkeren, kan du her lese et utdrag fra manualen til Assistent 100:
BIAS AND PCB
Traditionally, valve biasing is performed with a screwdriver to adjust the bias current to the valve. Any such adjustment can only be optimum for an instant as valves, even selected ones or a matched set, cannot hold a consistency of performance in the long term. Each valve will deteriorate individually and, if in a set, not necessarily in the same way as others in that set. A matshed pair or quad will therefore only remain matched for a relatively short period of time!
Helmut Becker of Audio Valve has developed a unique valve biasing circuit that automatically monitors, biases and controls each valve independently therby maintaining any number of valves at their optimum performance level. These valves do not even have to be of the same type or condition. This is Audio Valve´s Automatic Bias Regulation (ABR) circuit, a feature that audio Valve considers essential to deliver optimum performance from any multiple power valve amplifier and, in particular, to get the very best from the stunning 6C33.
Audio Valve´s ABR therefore delivers a long awaited dream - to combine the operational convenience of solid-state amplifiers with the sonic benefits of pure triodes. True 21st century valve-technology!
The PCB
All electronic components of the Assistent 100 are mounted on one double sided mil-spec printed circuit board created from a pure copper covered panel using CAD/CAM software to produce a circuit board completely free from solder bridges or point-to-point wiring. All signal and power tracks are separated by grounding tracks to minimise cross-talk and noice and the overall construction is designed to ensure low microphony and excellent conductivity.
The advantage of this approach is a consistency and reliability of performance and the certainty that all production examples of any Audio Valve model will be exactly like its reference sample! This is in stark contrast to amplifiers that employ hardwired components, where the sonic outcome will depend upon the construction technicians ability to solder all joints to a consistent standard and place the components in the same position and orientation as those of the reference sample to ensure consistency of interaction with other components.
Audio Valve´s PCB ensures that all components receive the same accuracy of assembly and that electro-dynamic interactions between components are constant in all aspects of the construction. Only the use of a well thought out and calculated printed circuit can achieve this. |
