RA-Twin II, $39.00 →Denon AVR-1604 Home Theater Receiver – 6.1 Dolby Digital/DTS, Very Good Condition, Tested, Includes Universal Remote
Experience the warm, authoritative sound of Denon’s AVR-1604—a mid-2000s home theater receiver that delivers true 75 watts per channel across 6 channels with Denon’s signature musicality and build quality. Featuring Dolby Digital EX, DTS-ES, and Dolby Pro Logic II decoding, this receiver brings movies and music to life with detailed surround performance. Thoroughly tested, in very good cosmetic condition, and including a pre-programmed universal remote (replacing the original Denon RC-941), it’s ready to anchor a quality home theater system.
True Denon Power & Performance:
The AVR-1604 delivers a genuine 75 watts per channel into 8Ω (20Hz–20kHz) with just 0.08% THD—a specification that reflects Denon’s conservative ratings and honest engineering. Unlike receivers that inflate specs with “peak” or “music power” claims, Denon’s numbers are real-world, sustained output. Users consistently report the AVR-1604 sounds far more powerful than its spec sheet suggests, driving speakers with authority and control.
The receiver features a 32-bit Analog Devices “Melody 32″ DSP processor and 96kHz/24-bit D/A converters on all six channels—premium components that ensure detailed, natural sound reproduction whether you’re watching action movies or listening to stereo music.
Advanced Surround Processing:
The AVR-1604 supports all major surround formats of its era:
Dolby Digital EX – 6.1-channel discrete surround for enhanced rear effects
DTS-ES Discrete 6.1 – True discrete surround back channel
DTS Neo:6 (Cinema & Music) – Upmixes stereo sources to 6.1
Dolby Pro Logic II (Movie & Music) – Enhanced matrix surround from stereo sources
Additional surround modes include Rock Arena, Jazz Club, Video Game, and 5CH/6CH Stereo for versatile listening options.
Connectivity & Features:
Component Video Switching: 2 inputs, 1 output with 30MHz bandwidth—excellent for DVD players and game consoles
Digital Inputs: 3 optical (including front-panel), 1 coaxial for CD players, DVD, or satellite
5.1 Multichannel Input: Direct analog input for SACD or DVD-Audio players
40 AM/FM Presets: Quality Denon tuner with excellent sensitivity
Two Sets of Main Speaker Outputs: A/B switching for multiple zones
Cinema EQ: Gently reduces extreme highs for overly bright soundtracks
Dynamic Range Compression: Perfect for late-night listening
Front-Panel A/V Inputs: Convenient connections for camcorders or gaming
Pre-Programmed Universal Remote Included:
This unit includes a third-party universal remote that has been pre-programmed to control the AVR-1604 and can be configured for your other components. While not the original Denon RC-941 remote, it provides full functionality and eliminates the hassle of sourcing a vintage remote.

Sound Character:
Denon receivers from this era are celebrated for their warm, musical sound—less analytical than Yamaha, more engaging than Pioneer. Users praise the AVR-1604 for “impressive middle range,” “impressive panorama,” and “excellent bass response”. The 96kHz/24-bit DACs ensure digital sources sound natural and non-fatiguing. While some reviewers noted the bass could be slightly “dimly deep” compared to Sony ES models, the overall consensus is that the AVR-1604 offers exceptional value and sound quality for its class.
Condition:
This unit is in very good cosmetic condition. The black faceplate is clean, all buttons function smoothly, and the chassis shows minimal wear.
Functionally Tested: All surround modes verified; all inputs (digital and analog) tested clean; AM/FM tuner locks stations reliably; component video switching working perfectly; all speaker outputs delivering full power.
Includes pre-programmed universal remote for full functionality.
Summary:
The Denon AVR-1604 represents the sweet spot of early-2000s home theater—genuine 75 watts per channel, comprehensive surround processing, excellent build quality, and that warm Denon house sound. Perfect for building a quality 5.1 or 6.1 system with vintage DVD players and efficient speakers. With testing, warranty, and a working remote included, it’s turnkey ready for your home theater.

Denon traces its roots to a Japanese record and gramophone company founded in 1910, and its name comes from denki onkyo, "electric sound". For decades it built broadcast equipment for Japan's NHK, and its DL-103 cartridge was developed with NHK. Since 2002 it has shared a parent company with Marantz. We carry Denon AV receivers, stereo receivers, integrated amplifiers and CD players. We've had more than 160 Denon listings so far. Every used Denon 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 Denon story
Denon says it first came into existence in 1910 as part of Nippon Chikuonki Shokai, the Japan Recorders Corporation, a record and gramophone company. Its direct predecessor, Japan Electric Sound Company, dates from 1939, and became Japan Denki Onkyo in 1944. The company joined Nippon Columbia in the 1940s.
Broadcast roots. From 1939 Denon supplied NHK, Japan's public broadcaster, with disc recorders and other broadcast equipment. The DL-103 moving-coil cartridge was developed with NHK in the 1960s and sold to the public from 1970.
Hi-fi. The DP-5000 of 1970 was Denon's first consumer record player, and the PMA-500 of 1972 its first integrated amplifier. Denon calls its DN-023R of 1972 the world's first practical PCM digital recorder. Its first consumer CD player, the DCD-2000, came in the early 1980s, and its first AV amplifier, the AVC-500, in 1985.
D&M and today. Denon was spun off from Nippon Columbia in 2001 and combined with Marantz in D&M Holdings in 2002. Sound United bought the group in 2017, Masimo bought Sound United in 2022, and in September 2025 HARMAN, a Samsung company, completed its purchase of Sound United.
Which Denon is which?
DRA stereo receivers: such as the DRA-625R of the late 1980s and the DRA-835R, up to the DRA-800H of 2019 with HDMI inputs.
AV receivers: the AVC line from 1985, AVR-numbered models such as the AVR-1800 and AVR-3808CI, and the AVR-X range from 2013.
PMA integrated amplifiers: from the PMA-500 of 1972 to current models such as the PMA-600NE.
DCD CD players: from the DCD-2000 and DCD-1800 onward, and DCM changers.
DP turntables: direct-drive models such as the DP-3000 (1972) and DP-7000 (1976), and 1980s automatic models such as the DP-47F.
DL-103 cartridge: a low-output moving-coil design, still made by hand at Denon's Shirakawa factory, Denon says.
Buying used Denon: what to check
HDMI boards. On modern AV receivers, HDMI is usually the first thing to fail; owners report failed HDMI boards on models such as the AVR-3808CI. Test every HDMI input and output, with the on-screen menus. We do that on every one we list.
2020 HDMI 2.1 models. Some 2020 receivers, such as the AVR-X2700H, could show a black screen with 4K/120Hz sources; a free external adapter was offered, and later units have the fixed chip. Ask whether the adapter comes with the receiver.
Output stages. Play any amplifier or receiver at a realistic level on both channels; owners report protection-mode faults after abuse.
CD players and turntables. Check tray belts and play several discs, including a CD-R. On an automatic turntable, play a full side, including auto return.
DL-103. It needs a moving-coil phono stage or step-up, and its low compliance suits medium- or high-mass tonearms.
Everything we list is inspected, tested and serviced as required here, and comes with our warranty.
