Azur 840A Class XD™
Integrated Amplifier

"Een bijzonder aanbevolen set: alle drie zijn van bijzondere klasse, zowel in het gebruik als in kwaliteit. Ook de bouw ziet er puik uit. Wanneer u het geld er voor (over) heeft zult u niet gemakkelijk iets vinden met dezelfde faciliteiten, geluidskwaliteit en afwerking."

"A set highly recommend: all three are of exceptional class, in terms of quality and use. The build quality is superb. If you have the money you won’t find anything with the same facilities, sound quality or finish."

It handles simple and complex music with equal skill as well as loud and soft dynamics. After all, it takes a special kind of amp to play both loud and soft material well."
