Classé - DELTA Stereo Review: A Compact Powerhouse That Commands Attention


Classé - DELTA Stereo Review: In an era where audiophiles crave both space-saving design and uncompromising sonics, the Classé – DELTA Stereo emerges as a true marvel. This stereo amplifier distils Classé’s decades of innovation into a single chassis, delivering the heft of dual mono rigs in a beautifully crafted package.

Design & Build Quality

At first glance, the DELTA Stereo makes a statement. The illuminated VU meters—custom-designed and instantly recognisable—sit proudly on the brushed-aluminium fascia, signalling both performance and poise. Beneath the panel, six-layer, hand-laid circuit boards shorten signal paths and lower noise, while 22 four-pole Mundorf® capacitors and a massive custom toroidal transformer ensure rock-steady power delivery. Navcom® vibration-absorbing feet and Furutech® rhodium-plated RCA and torque-guard speaker connectors complete the package, guaranteeing that every grain of detail emerges unblemished.

Amplification That Excels

Under the hood, the DELTA Stereo flexes serious muscle. The first 12.5 W per channel operate in pure Class A, unlocking the harmonic richness and immediacy audiophiles crave. When you demand more dynamics, the amplifier seamlessly transitions to full power—250 W into 8 Ω, and a staggering “over-350 W” into 2 Ω speakers. With <0.0016% THD+N at 1 kHz and a slew rate of 75 V/μs, the DELTA Stereo reproduces complex passages with unwavering control and zero strain.

Uncompromising Clarity & Soundstaging

Classé’s obsession with channel separation shines through in the DELTA Stereo’s expansive soundstage. With crosstalk figures of 124 dB at 100 Hz and still 90 dB at 10 kHz, the amplifier paints a holographic image, delineating performers and instruments with laser-like precision. A signal-to-noise ratio of 118 dB (120 dBA) ensures that even the subtlest decay of piano pedals or the faint breath of wind in orchestral recordings remain audible and alive.

Who Should Consider the DELTA Stereo?

• Audiophiles Seeking Class A Warmth: Enjoy the first 12.5 W of pure Class A operation for acoustic jazz or intimate vocal recordings.
• Power-Hungry Loudspeaker Owners: Drive 4 Ω or even 2 Ω speakers without ever feeling underpowered, thanks to its robust 500 W at 4 Ω (AC constant).
• Space-Conscious Enthusiasts: Get dual-mono performance where two mono blocks won’t fit, all in a single 444 × 492 × 222 mm chassis.
• Design-Focused Setups: Match the DELTA Stereo’s iconic VU meters and premium finishes with high-end turntables, DACs or preamplifiers.
