Reviews
“Classé’s Delta PRE and STEREO are impeccably designed and manufactured products that offer impressive operational flexibility and dependability. These two components are visually appealing and practical to install in a domestic setting. The Delta PRE and STEREO were a pleasure to operate and, more importantly, to listen to.” – Andrew Quint – the absolute sound
“A first-class demonstration from A to Z: there is hardly a better way to sum up the presentation of the new Classé Delta preamplifiers and power amplifiers.” – Martin Freund – guide.ch
Clarity
Classé Delta STEREO Power Amplifier delivers exceptional clarity. Every effort has been made to preserve complete separation between channels, delivering the natural, expansive sound that Classé is legendary for.
- Hand-laid circuit boards
- 6-layer circuit boards provide for shortened signal and power pathways with lowest noise
- 22 4-pole Mundorf® capacitors
- Custom-made Navcom® feet to absorb vibrations
- Furutech® rhodium-plated RCA and torque-guard speaker connectors
Design
With the Classé Delta STEREO Power Amplifier, it has presence. It’s capabilities are expressed through design and it looks fantastic in any room or installation.
Superb material finishes and a pair of custom-designed illuminated VU meters display power output for both channels beautifully.
Delta Series design concept is to create a monument to sound. The Classé Delta STEREO Power Amplifier looks every bit has capable as it sounds.
