Amp II
$25000
The AMP II – MK4 is a so-called “dual-mono power amplifier”, i.e. apart from the common mains cable both channels are completely separated from each other – from the transformer to the output stage board. This ensures the excellent values, for example, for channel separation and signal to noise ratio, etc. The AMP II – MK4 works with Class A operation in most applications. And, despite its enormous power, the AMP II – MK4 reproduces the finest details with extreme precision, in our opinion just as one would expect from a real reference product.
