The Delta Stereo sports both balanced and unbalanced inputs, and has two sets of high quality rhodium-plated copper five-way binding posts with Torque-Guard to avoid over tightening them. In Australia, all Delta Series amplifiers come with a high-performance AC power cable made in the country and fully certified. This beast of an amplifier has a net weight of 46.4kg, so it is definitely a two-person job to set up. Performance and durability are also mentioned as goals, and I get the sense that shortcuts were never an option with the design and execution of the new Delta series. The result is an amplifier capable of driving virtually any loudspeaker very well. MOSFETs are used in the output stage.Ĭlassé told me that one of the design goals for the amplifier was to make something that would easily drive B&W 800 Series speakers, which required a shift to a lower voltage, higher current design. Then there are the twenty-two individual four-pole Mundorf capacitors for 215,000uF of filtered energy potential. This is shaped for minimal noise and maximum cooling effect, with a thermostatically controlled variable speed fan which proved almost silent to those sitting a couple of metres away.Ĭare has been taken with the design and execution of the power supply of this amplifier, the company says, with the use of a custom hand-wound toroidal transformer with separate windings for left and right channels. A removable front louvre is complete with a cleanable air filter used as the inlet for the unit's so-called ICTunnel active cooling system. The front panel is dominated by the large and easy to read VU meters. ![]() This might not seem much, but many will struggle to push it beyond this figure with reasonably efficient modern loudspeakers. The Delta Stereo is a powerful two-channel power amplifier with a rated output of 250W per side into 8 ohms, with the first 12.5W being pure Class A. ![]() With either white on black VU meters or a touch panel display using a minimal amount of front panel buttons, it's a seriously sophisticated aesthetic. The styling is modern and timeless, and the pair look fantastic stacked on top of one another. Many neat small touches add up to a highly accomplished design, including the custom Navcom feet with isolation control. They are finished in a dark charcoal finish called architectural grey. Not exactly spare change, so expectations are high…īoth new Delta amplifiers use the familiar one-piece heavy gauge aluminium curved front styling common to the previous generation of Classé products. The subject of this review is the Delta Stereo power amplifier at $19,900 and the Delta Pre preamplifier at $16,900. There are three new models, the Delta Mono and Stereo power amplifiers and the Delta Pre. This is the third generation of the Classé Delta series amplifiers and easily the best yet. It has the resources, the team and the desire to produce world-class products that build on the company's illustrious heritage. ![]() And it's back with a brace of new products and something to prove. The Canadian company now operates under the umbrella of Sound United, along with brands such as Denon, Marantz and Bowers & Wilkins. ![]() Classé Audio Delta Preamplifier | Delta Stereo AmplifierĪUD $16,900 RRP | $19,900 RRP respectivelyĬlassé Audio has come a long way from its first stereo amplifier, the DR-2 launched in 1980 – but its love of Class A power has not changed.
