DarTZeel NHB-458 Mono Amplifier

Quick Overview

DarTZeel NHB-458 Ultimate Monoblock Amplifier

With the final darTZeel NHB-458, it sets a new standard: after nine years of constant research and continuous development, this amplifier, not only it owns all the qualities of the NHB-108, already acclaimed by the whole audiophile world, but it goes further in revealing a very special machine in every respect. Some key features -The output is still higher than that already showed off the prototype presented in Las Vegas in 2009, and that with further improvements and stronger power: 450 watts RMS into 8 ohms, 800 into 4 ohms and 1000 ohms to 2 , resulting in more than 500, 900 and above, with control of the security offered by security software, the dynamic reproduction of music signals (an additional increase of the actual power generated will also depend on the voltage of power supply, often above, in practice, the nominal value of 230 Volts).
