Parasound HALO (John Curl) HCA3500 Dual Mono Power Amplifier (used)
SALE PENDING
This is a consignment item from an estate, there's no sales tax. Very heavy amplifier, local pick-up only please.
One of the monster power amps from Parasound's HALO series, the HCA3500 is a dual mono design by John Curl. It can deliver about 15W Class A before reverting to Class AB. In good working condition with no apparent issues. Cosmetics are ok, about 6/10. Double boxes and packaging included; two power cables and a reprint of the owners manual.
"Priced at what, in a high-end context, is a very reasonable level, the HCA-3500 offers performance that in many ways approaches that of the cost-no-object blockbuster amps." Robert Deutsch, Stereophile (Jan 2000)
