Parasound A21 Power Amplifier Parasound A21 power amplifier.A lovely power amp with an effortless performance.https://www.theabsolutesound.com/articles/parasound-halo-a-21-stereo-amplifier/Many think it a superior amp to the superceding A21+. Google A21 vs A21+. I have recently discontinued using subwoofers with my Magnepan speakers (also driven by a Parasound) so it is superfluous to my needs (driving the subwoofers). I've used it for about 4 years and had purchased it from a close friend who purchased it new. It has proven faultless with one exception (hence the very reasonable price). It ha
With condition unknown on this used Parasound A21+ speakers listed at AUD$1,900, that's a compelling bargain against recent comparable AUD sales—median AUD$2,238, dipping to AUD$2,114 at the 25th percentile and up to AUD$2,984 at the 75th. The opacity screams caution, but if it's clean and functional, you're stealing it well under market; anything less pristine justifies the discount.
Before biting, insist on close-up photos of the drivers—no tears, cone deformities, or surround rot, as these Parasounds chew through foam edges over time—and a full functional test for buzzing, distortion, or channel imbalance. Verify original grilles, binding posts free of corrosion, and any service history; skip if no original boxes or stands included, as resale tanks without them.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Parasound, an enduring American hi-fi brand, traces its roots to 1981 when Richard Schram founded it in San Francisco, California. Drawing from his experience in consumer electronics retail and engineering trips to Asia, Schram aimed to bridge the gap between exorbitantly priced high-end gear and lackluster budget options. His vision crystallized through savvy U.S. design paired with cost-effective manufacturing in Taiwan, establishing Parasound as a beacon of accessible excellence from the outset.
The brand excels in amplifiers and preamplifiers, its core stronghold, with the acclaimed Halo series embodying decades of refinement. Iconic collaborations with legendary designer John Curl—starting in 1989—elevate power amps, phono stages like the JC3+, and processors to reference-level performance. While not venturing into speakers, turntables, DACs, headphones, or cables, Parasound's focused lineup delivers uncolored, dynamic sound through innovative circuits and robust builds.
Parasound occupies a prime mid-to-high-end niche, revered for punching far above its price weight with reliability that rivals pricier boutique rivals. Audiophiles and critics praise its value-driven sonic fidelity, build quality, and longevity, fostering fierce loyalty worldwide. Even under new ownership since 2022, it remains the discerning buyer's choice for high-performance audio without prestige-driven excess.
