v40 Blackline

Enjoy the warm rich sound that valve amplification provides now in a retro walnut finish. Following on from critically acclaimed press reviews for our v40 hybrid tube amplifier, the v40 Limited Edition is now available in a sumptuous high gloss walnut finish and presented in distinctive Limited Edition packaging. Matching high gloss walnut loudspeakers are offered as part of the system. Primarily sold as a combined amplifier/loudspeaker system, both products can also be purchased separately.

Our Blackline range goes from strength to strength with the latest addition, the v40 Limited Edition. The v40 LE amplifier has all the technical attributes of the standard v40 and is presented in a high gloss walnut finish.
Both sonically and aesthetically matched, the ps40 LE loudspeakers are offered as part of the system.

Eight coats of clear lacquer have been applied to the amplifier facia and the loudspeaker enclosures to give a deep, luxurious finish to the walnut veneers.


As a result of customer demand we have developed a new loudspeaker to partner the v40 LE amplifier, an upgrade from our standard ps40's.
A slightly larger enclosure is used to allow increased cabinet volume.
The tweeter selected by our acoustic engineers for the ps40 LE is an AMT (Air Motion Transformer) type. AMT tweeters offer excellent transient response and low distortion ratios, resulting in a more natural and musical ambience to be heard.

The low frequency drive unit is a 4.5” Hemp impregnated cone type. Hemp has less cone break up and distortion than other fibre coned drive units and improves tonality and resolution. 
High quality audio components are used for the filter network ensuring delivery of a clean audio signal.   Both the amplifier and loudspeakers have Limited Edition insignia and are supplied in bespoke packaging.
