Description

The Delta STEREO distills all of Classé’s innovation and knowledge into a compact high-performance stereo amplifier.

In situations where dual mono amplifiers can’t be accommodated, Delta STEREO offers uncompromizing performance in a single component.

AMPLIFICATION 

The first 12.5W of power output are pure Class A, and with a total of 250W per channel at its command (over 350W/Ch @ 2Ω), this compact, powerful amplifier drives loudspeakers with utmost confidence.

  • Up to 12.5W per Channel delivered in pure Class A operation
  • 250W per Channel total
  • Massive, high-quality power supply
  • Custom toroidal transformer

CLARITY 

Delta STEREO 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 

Delta STEREO 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. This amplifier looks every bit has capable as it sounds.

 

REVIEWS

Home Theater Review - Editor's Choice 2022

We were delighted to read Mark Henninger’s article in Home Theater Review. Mark awards the Classé Delta STEREO Amplifier “a perfect 10”. He describes the Delta STEREO as “capable of driving any of the speakers that I connected to it—to their limits—without reaching its limits” whilst “maintaining all of the recording’s clarity and transparance, leaving nothing but the music to listen to.” Herewith more excerpts of his review:

In May 2021, Mark Gusew reviewed our combination of Delta PRE and Delta STEREO. He was “blown away by this classy preamp/power amplifier combination…”. He goes on to write: “The flexibility and capability is phenomenal, and it’s obvious that much care has gone into the design and manufacture of this pair with the overall build quality and finish up to the highest standards available anywhere. […] This combination has abilities well beyond the asking price, so is heartily recommended.” Herewith some excerpts of his review:

Award Logo - Stereonet 2021

This is the third generation of the Classé Delta series amplifiers and easily the best yet.

Many neat small touches add up to a highly accomplished design, including the custom Navcom feet with isolation control. The styling is modern and timeless, and the pair look fantastic stacked on top of one another. 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.

 

review-logoAndrew Quint of renowned Audio Magazine “The Absolute Sound” was the first to review the combination of Delta PRE and Delta STEREO in North America. He did so for over a month and was impressed by the Delta models to deliver a transparency that, so far, had only been equaled by more expensive audio components in his reference setup. A link to the full article is included at the bottom of this page.
