Harman Kardon AVR 325 7.1 AV Receiver 50WPC – 40 lbs! w/ Remote
7.1-channel Harman Kardon home theater receiver with high-current amplification, Dolby Digital EX, DTS-ES, Logic 7 processing, and component video switching, in good condition with original remote.
The Harman Kardon AVR 325 is a substantial 7.1-channel AV receiver from the mid-2000s, designed to deliver Harman Kardon’s signature high-current amplification and polished sound quality in a full-featured home theater package. Rated at 50 watts per channel across all seven channels (65 watts in stereo mode) into 8 ohms, this receiver uses a robust power supply and discrete output stages that give it surprising dynamic capability and control over real-world loudspeakers. The AVR 325 supports Dolby Digital EX, DTS-ES (both matrix and discrete), Dolby Pro Logic II, DTS Neo:6, and Harman Kardon’s proprietary Logic 7 Cinema and Music modes in both 5.1 and 7.1 versions, creating a wide, enveloping surround field from a variety of source material. This unit is in good cosmetic condition and includes the original Harman Kardon remote.
The back panel offers generous connectivity: three optical and three coaxial digital inputs (one of each on the front panel for convenient access), two component video inputs with wideband switching for HDTV sources and progressive-scan DVD players, plus composite and S-video connections for legacy gear. An eight-channel analog input accommodates external decoders or multichannel sources like SACD and DVD-Audio players. The seven amplifier channels are configurable for either 7.1-channel operation or 5.1-channel main room plus powered stereo Zone 2, making the AVR 325 a capable whole-house audio hub. AM/FM tuner with 30 presets, on-screen display, and RS-232 control port round out the feature set.

Harman Kardon began in New York in 1953, founded by Sidney Harman, who was born in Montreal, and Bernard Kardon. Harman Kardon calls its 1954 Festival D1000 the first hi-fi receiver. We carry Harman Kardon stereo receivers, AV receivers, integrated amplifiers, cassette decks and CD players. We've had more than 130 Harman Kardon listings so far. Every used Harman Kardon here is inspected, tested and serviced as required, then photographed in-house and covered by our Bumper-to-Bumper Warranty and Perpetual Trade-Back Program. Every AV receiver we list is tested input by input on our bench: each HDMI input and output, the analog, optical and coaxial inputs, the subwoofer outputs and the wireless features where it has them.

The Harman Kardon story, 1953 to today
Sidney Harman and Bernard Kardon left the David Bogen Company, where Kardon was chief engineer, and founded Harman Kardon in New York in 1953. Harman was born in Montreal in 1918 and grew up in New York. Kardon retired in the 1950s.
Receivers first. Harman Kardon calls the Festival D1000 of 1954 the first hi-fi receiver and the Festival TA230 of 1958 the first stereo receiver. The Citation II tube power amplifier of 1959, designed by Stu Hegeman, sold as a kit or ready-built.
Cassette and the 1970s. Harman Kardon says its CAD-5 of 1970 was the first hi-fi cassette recorder with Dolby noise reduction. Its "Twin Powered" receivers of the 1970s, such as the 430 and 730, gave each channel its own power supply.
Owners. Sidney Harman sold the company to Beatrice Foods in the late 1970s, when he became US Deputy Secretary of Commerce. He formed Harman International in 1980 and bought Harman Kardon back in 1985. Samsung bought HARMAN in 2017, and Harman Kardon remains one of its brands.
Which Harman Kardon is which?
Tube era (1950s and 1960s): Festival receivers, and Citation kits and factory-built units such as the Citation I preamplifier and II amplifier.
1970s receivers: the 330 series, the Twin Powered 630, 930, 430 and 730, and the HK670.
1980s receivers: the "i" models such as the hk690i, advertised for its high current capability, and the 330i.
Citation separates: solid-state Citation amplifiers and preamplifiers from 1970 to the 1990s, including the Citation XX of the early 1980s.
Cassette decks: from the CAD-4 and CAD-5 to the 1980s decks numbered CD91 to CD491. Those "CD" models are cassette decks, not CD players; Harman Kardon CD players carry "HD" names.
AV receivers (late 1990s on) and later stereo: the AVR line, such as the AVR 3600, and stereo models such as the HK 3700 and HK 990.
Buying used Harman Kardon: what to check
Dial and meter lamps. Owners report dead or flickering lamps on 1970s receivers such as the 930, 430 and 330C; many are replaced with LEDs.
Capacitors. Expect a 1970s receiver that hasn't been recapped to need it.
Output stage. Owners report blown output transistors on the 730 and 430, often caused by a failed part nearby. Both channels should play cleanly at a realistic level.
Switches. Owners say the 1980s "i" receivers are prone to dirty switches that make channels cut out. Try every input and the balance control.
AV receivers. HDMI is usually the first thing to fail on a modern AV receiver. We test every HDMI input and output before listing.
Everything we list is inspected, tested and serviced as required here, and comes with our warranty.
