Quick Overview


Not available - please enquire


The Sugden Grande Amplifier is a Mono Block Amplifier operating in Pure Class ‘A’ mode (there are two Grande amplifiers for stereo reproduction).

Each mono block houses dual matched amplifiers with the output stages in the floating bridged mode. The amplifiers are best described as instrumentation, class ‘A’, floating bridge power output amplifiers, dc coupled with current feedback.

The amplifier is equipped with an input board with user logic switching for balanced or phono/asymmetric inputs. Also on the input board is a six dB attenuation facility for input signal matching.

There are two power output levels, an ‘Eco level’ for low level listening where the power consumption is reduced by 75% and concert hall /auditorium level to take full advantage of the units fatigue free uncompressed massive sound stage.

Sugden’s 50 years experience of designing and manufacturing class ‘A’ audio amplifiers for the discerning music lover ensures the advantages of class ‘A’ are fully realised.

The mono blocks are housed in an aluminium chassis with massive extruded aluminium heat sinks for the necessary heat dissipation associated with pure class ‘A’.

Whilst this descriptive text includes a technical bias, Sugdens Philosophy of ‘Rescuing Music from Technology’ has been fully exhausted to develop a product that provides ‘simply more music’.

The Grande is the most powerful pure class ‘A’ amplifier of the Sugden lines and has involved intense development over a period of years. Many thousands of hours have been spent on circuit layouts, component selection, overall physical relationships of the circuitry and its main case. From the balanced or asymmetric input through the controlled gain stages to the floating bridged output and final tuning, absolutely no compromises have been made in achieving an exceptional amplifier with remarkable musical performance.
