Parasound NewClassic 275 V2 Review: A Powerhouse 1U Amplifier

Embark on our Parasound NewClassic 275 V2 Review – a deep dive into one of the most compelling two-channel power amplifiers in its price bracket. With an ultra-slim 1U chassis and robust performance that belies its low-profile design, the 275 V2 is engineered to deliver precision, power, and reliability for discerning audiophiles.

Design and Build Quality

The NewClassic 275 V2 flaunts a sleek 1U rack-height profile, measuring just 44.1 mm on the front panel. Under the bonnet, Parasound has packed a high-current toroidal transformer and fully discrete circuitry into a compact footprint. Gold-plated five-way speaker terminals, robust binding posts, and gold-plated RCA inputs ensure signal integrity. Front-panel A/B speaker selectors with an optional rear-mounted lockout switch add functional versatility, while sturdy construction keeps vibrations at bay.

Performance and Sound

Delivering 90 watts per channel into 8 Ω with all channels driven (150 watts per channel into 4 Ω or 2 Ω), the 275 V2 punches well above its weight. Bridged mono mode yields a commanding 200 watts into 8 Ω or 4 Ω, making it ideal for demanding speaker loads or subwoofer duties. With 20 amps of peak current, dynamic headroom of 1.3 dB and a damping factor exceeding 150 at 20 Hz, bass response is taut and controlled. Total harmonic distortion sits at a minuscule 0.35% at full output (dropping to 0.025% at normal listening levels), while signal-to-noise ratios reach 110 dB (IHF A-weighted), ensuring an exceptionally clean background. The result is articulate mids, detailed treble and a soundstage that’s both expansive and precise.

Features at a Glance

• Switchable high-pass filter at 20 Hz or 40 Hz
• DC trigger and audio-sensing auto on/off with dual sensitivity
• Switchable stereo/bridged mono operation
• Rear-mounted gain controls and 115/230 V selector
• 24 k gold-plated five-way binding posts and RCA inputs
• Efficient low-heat design with DC servo and relay protection circuits
