Masterpiece Class A Monaural Amplifier

Description

Class A amplifiers have always had the reputation of warmth and a great soundstage and although class D amplifiers have made a great way forward in recent years, there are still many benefits to Class A and MOSFET designed power amplifier designs.

Excessive heat, high power consumption, low damping factor and relatively low output power. All these aspects does not bring confidence to the discerning audiophile how-ever as always, it is in the listening where this approach to amplification brings a certain joy and pure audio realism to the equation.

My own reference system now utilises these monaural amplifiers along with the latest Masterpiece Edition tube pre-amplifier and in terms of preference the MB10 Class D mono block amplifiers which are incredibly good, now comes behind these amplifiers.

The reasons are many but primarilly it is about that elusive holographic presentation, a lack of edge to vocals and instruments such as piano and pure realism to live recordings which gives an accurate sense of space and depth to a recording.

Digital recordings have a more organic and analogue feel and vinyl takes on an even more beautiful and beguiling nature making you want to explore your vinyl collection yet again and buy new records.

As with all the masterpiece editions, this model is hand crafted using exotic materials and components. Bolivian Rosewood, dampened aluminium construction and silver wiring are standard.
