Robson MB2

The MB2 Monoblock amplifier is based around the legendary Hypex NCore 500 amplifier module and housed in a high end diamond engraved aluminium case. 

Capable of superbly holographic imaging and a vastly layered and wide soundstage. Vocals are vivid and real with a convincing portrayal of musical emotion.

Possibly the most accurate and detailed amplifier in the world with incredible dynamics and control and a perfect match for our range of tube pre-amplifiers.

MB2 features

  • Rhodium plated poles connectors
  • Duelled Coherent internal wiring
  • Voice of balanced or un-balanced input
  • Choice of output power with the same sonic signature

High current and damping factor the MB2 will drive the most difficult of loads with breath taking control and power.

Monoblock Amplifier MB1

Robson Acoustics new Monoblock Amplifier MB1 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!

The Monoblock Amplifier MB1 is 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.

  • Acoustic tonewood cabinets
  • Low standby consumption
  • High input impedance
  • WBT pole connectors
  • Solid silver wiring
  • Huge damping factor
