Beschrijving


Te koop wegens upgrade: de Europese referentie op het vlak van eindversterking in de klasse tot €15k versterkers.

Dit is de Amp II Mk2: deze heeft de hoogste score in Duitsland. Zie reviews en testen online. Een zware (50kg) versterker die moeiteloos de moeilijkste luidsprekers aanstuurt en het maximale eruit haalt.

Test resultaat Stereo:
To conclude, we would like to quote “STEREO” once more:
Test result: “The amplifier is a model of stability and precision while at the same time versatile and agile, making the product a textbook example of how to build an amplifier. Homogeneous, universally usable, virtually perfect. And for this high-end product, an unbelievably reasonable price”.
