Class A Stereo power amplifier

Class A Stereo Power Amplifier

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, is there still room for this old design of amplification in the modern world?

Excessive heat,  high power consumption,  very low damping factor and low power output. All these aspects and small amounts of hum 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 that answers the question earlier.

My own reference system now has this amplifier along with the latest MV2 tube pre-amplifier and in terms of preference the Class D N-core 1200 mono block amplifiers which are incredibly good, now comes third behind this stereo power amplifier and the 300B tube integrated amplifier.

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, copper panels and silver wiring are standard.

This stereo amplifier will soon be complimented with a matching tube pre-amplifier. Watch this space.
