The JOB 250 mono amplifier is a unit of 250W power in a reasonably small chassis. Totally protected, easy to use, perfectly silent, it is THE power amplifier for an audiophile who is conscious of his budget but demanding the absolute in terms of sonic quality. With its extraordinary dynamic capability and its unconditional stability, it can drive anything.
More, with the JOB proprietary Ultra-Control” of the speaker, any speaker even a large one will sound better when used with JOB 250.
With extremely low distortion, especially IM distortion, literally zero group delay distortion, ultra wide Megahertz bandwidth and DC coupling, extreme silence and cool operation, it can be played at high level with the same impression of ease as at low levels.
Thanks to the JOB Electronics large scale of operation on power amplifiers , the JOB 250 is also offered at a realistic price , where high end audio manufacturers would charge much higher amounts if the same amplifiers were sold through the traditional channels.
To achieve exceptional sound quality, we needed exceptional construction quality. We picked the best components on earth, and have them assembled by Swiss companies who can guarantee the most accurate work on our products. No amateurism accepted. And to be sure of what we deliver, we test the finished product by running it for a week. The result is an exceptional reliability with the lowest failure rate we could even have dreamed of.
