"PrimaLuna’s DiaLogue Premium HP is an integrated amplifier whose sound quality closely approaches that of pairings of reference Class A preamps and power amps."
When a replacement for the awe-inspiring DiaLogue One and DiaLogue Two integrated amplifiers were being penned by the PrimaLuna engineers in The Netherlands, it was already known that there was a difficult job ahead. They had to exceed the performance of two products that were some of the best reviewed in the industry, that's how new Dialogue Premium Integrated Amplifier was born.
Incorporating the best electronic elements of the original ProLogue Series, plus selected ground-breaking features from the more advanced DiaLogue Series, the next generation ProLogue Premium Integrated Amp is an engineering marvel — a single, integrated amplifier that sets a new benchmark in high-performance audio with the following features: *Innovative, new Adaptive AutoBias™ circuitry.
The IA-4 is Sugden's flagship and most popular integrated amplifier. Weighing a substantial 20 kilos the IA-4 has a purposeful look and impressive build quality. Plenty of input and output facilities are on offer including a high quality phono stage.
The special edition A21SE integrated amplifier builds on the strengths of the classic A21. Offering pure class A single ended operation, the sound remains distinctively ‘Sugden’. Upgraded with a fifty percent larger power supply and increased power output, dynamics are even more impressive. A sophisticated pre-amplifier stage is another improvement on the A21. This provides greater clarity without added brightness producing crystal clear highs. The larger power supply provides greater control over a wider range of loudspeakers and improved micro dynamics for low level listening.
