Fully working, no issues whatsoever, tons of power! There is no way around it; this is big, heavy, and expensive to ship! I have a very, very strong box for it. Boxed up, it's about 100lbs, and big! Local pickup would be ideal, but I will ship it. The Parasound HCA-3500 is a massive, dual-mono high-current power amplifier designed by legendary audio engineer John Curl. [1] (), [2] ( SpecificationsPower Output: 350 watts per channel into 8 ohms; 500–600 watts into 4 ohms (20Hz–20kHz).Design: High-bias Class A/AB, maintaining pure Class A operation up to 15 watts into 8 ohms.Current Capacity: 120 amps peak per channel.Dimensions & Weight: 19 inches wide by 7.75 inches high by 18 inches deep; weighs a heavy 100 lbs.Inputs: Features both balanced XLR and unbalanced RCA connections
This is a fair ask, leaning slightly to the buyer-friendly side: at US$1,200, it sits just under the US$1,250 median and right around the US$1,225 lower quartile, so it reads as a sensible market price rather than a bargain-bin score. Given the wide spread up to US$5,039, this is comfortably away from the lofty end of recent asking prices.
That makes it a worthwhile look if the unit is clean and functioning properly, because Parasound’s big HCA amps are well liked for strong current delivery, solid grip on speakers, and a generally muscular, no-nonsense presentation. The real upside here is value if the cosmetics are decent and the seller can confirm stable operation; at this price, I’d want a clear description of condition, proof it powers up cleanly, and confirmation that there are no channel or protection issues.
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.
