Following the Reference Preamp, the Swiss company Nagra has introduced the Nagra Reference AMP monoblock power amplifiers. The model replaces the well-known Nagra HD AMP and boasts a 25% larger power supply with 2000 VA transformers.
The Nagra Reference AMP offers a number of other improvements - from an engineering point of view, mechanical stability has been improved (a three-stage mechanical damping system is used) and advanced decoupling feet featuring phenolic and pure copper have been used, and in terms of music reproduction - tolerance to various genres.
The Nagra Reference AMP uses a completely new input circuit with super low impedance and can provide higher output power in Class A mode than the previous model (released ten years ago). It is also worth noting the new internal wiring with High End class cable, as well as WBT Next-Gen speaker terminals.
The Nagra Reference AMP is also equipped with a damping factor control system - the user can choose two modes, the first for deeper bass and the second for tight bass to match your speakers or room
