The 640A builds upon the impressive features of the 540A resulting in a quality of performance
you would expect from amplifiers costing considerably more. This development provides true audiophile levels of
sound reproduction and takes the Azur marque to the highest level.
Output is 65 watts per channel into eight Ohms and the inclusion of a Class 'A' follower driver stage, together with high
quality polypropylene bypass capacitors reflects the attention to detail that sets the 640A apart from its rivals.
