Robson Acoustics new Monoblock MB1 amplifiers represents the latest in high efficiency class D amplification and the beauty of hand crafted solid hardwood cabinets.
The first of a range of products following our love of natural materials and design approach to compliment our tube Pre-amplifier, Phono stage and our range of speakers.
Able to dig out the minutest detail from recordings without the harshness or fatigue associated with many class D amplifiers.
Hearing is believing!
Capable of driving virtually any speaker with 500W’s of incredible dynamic and controlled power, low output impedance and optimised input stages.
Honed out of solid walnut to give both beauty and acoustic resonance control reducing the outside impact on the sound together with solid brass feet for vibration isolation. Walnut is well known for it’s textured and earthy tone and a great compliment to these amplifiers.
Fine solid silver wire is used for input and output connections with WBT binding posts for the ultimate retrieval of audio signal.
Optional input for balanced or single ended to eliminate switching and available on customer request where Lundahl transformers are used to isolate and match other equipment.
