Marantz HD-AMP1 overview

  • 1Description

Enjoy high-resolution stereo sound with the Marantz HD-AMP1 Integrated Amplifier. It delivers up to 35W per channel at 8 Ohms and has two optical inputs, one digital coaxial input, and two RCA stereo inputs. The HD-AMP1 also features an integrated DAC for the playback of files stored on a USB device or a computer.

High-Resolution Audio Decoding
Equipped with the reference-class ESS SABRE DAC that's paired with Marantz HDAM-SA2 technology, the HD-AMP1 is designed to deliver a high-resolution listening experience and is capable of decoding uncompressed audio tracks up to 32-bit/384 kHz as well as DSD tracks (2.6/5.2/11.2 MHz). For enhanced D/A conversion with virtually any sampling frequency, the HD-AMP1 is equipped with dual master quartz clocks.
Marantz Musical Digital Filtering
Marantz Musical Digital Filtering technology utilizes proprietary digital filter algorithms that are designed to extract the utmost fidelity with high-resolution audio tracks, and the HD-AMP1 has two different digital filtering options so you can easily tailor the sound quality to your preference.
Dual USB Ports
The front panel features a USB port for direct connection to your favorite iOS device, USB thumb drive, or NAS. The rear panel USB-B port is reserved for direct connection to your Windows or Mac computer so you can stream your favorite high-resolution music tracks, and it features advanced noise isolation to help prevent digital noise from degrading the audio fidelity.
USB Auto Charge Function
Listen to your favorite iOS device via the front-panel USB port and charge it at the same time. When the HD-AMP1 is put into standby mode, your device continues to charge until the battery reaches full capacity; then charging is automatically stopped. The USB port delivers a 1A current output, the same current output provided by many smart device USB chargers.
Class-D Digital Power Amplifier
The cool-running Class-D digital power amplifier is designed to deliver wide frequency response (up to 50 kHz), wide dynamic range, and low distortion.
Marantz Current Feedback Technology
First introduced in the Marantz tube amplifiers more than 55 years ago, the Marantz Current Feedback technology is designed to provide natural warmth and musicality, helping the HD-AMP1 deliver augmented audio fidelity for an enjoyable listening experience.
Marantz HDAM-SA2 Technology
Instead of using conventional IC chip op-amps, HDAM technology features precision discrete component circuit blocks that deliver wide frequency response, a fast slew rate, and low distortion. The HD-AMP1 features HDAM-SA2 in three circuit blocks, including the analog front end, the D/A converter section, as well as the dedicated headphone amp block.
Multiple High-Resolution Lossless Audio Formats Supported
For a wide range of high-resolution lossless audio tracks, the HD-AMP1 can decode WAV, ALAC, FLAC, and AIFF audio file types. It can also decode MP3, WMA, and AAC tracks as well. Via the front-panel USB port, the HD-AMP1 supports up to 24-bit/192 kHz high-resolution files, while the rear-panel USB-B port supports up to 32-bit/384 kHz high-resolution tracks. Also, the HD-AMP1 can decode all 3 DSD sampling frequencies – 2.6, 5.2, and 11.2 MHz.
Dual Analog Inputs
For compatibility with analog audio sources such as a tuner, tape deck, or any other source that's not equipped with digital audio outputs, the HD-AMP1 features 2 analog inputs.
Dedicated Headphone Circuit with Adjustable Gain and HDAM-SA2
Designed to deliver an enhanced listening experience with a wide range of headphone types and impedances, the HD-AMP1 features a dedicated headphone amplifier block that employs Marantz's HDAM-SA2 technology. There are 3 gain settings available in order to match a wide range of headphone impedances.
Premium-Grade Connectors
The rear panel features gold-plated analog and coaxial input connectors, along with Marantz's SPKT-1 speaker connectors, which feature multi-way connection capability for compatibility with a wide range of speaker cable terminations.

    Marantz HD-AMP1 reviews

    HD-AMP1 Integrated Amplifier is rated 5.0 out of 5 by 2.
    Rated 5 out of 5 by from Punches above it’s weight Purchased this three weeks ago to replace an aging Denon integrated amp.  It’s been a remarkable upgrade. I have a pair of vintage Infinity RS4b speakers. The Denon never really seemed to get them to perform. Not so with this Marantz. Forget the specs.  This unit has half the WPC but drives these speakers with no problem. I’m playing CDs using a Rotel player from the ‘90s and it’s a good match to this amp. I’m relistening to my CD collection and hearing them like they were new. The iPod/USB connection is excellent. I’m streaming tracks from Tidal and it matches CD quality. I’ve listened to a lot of gear and I can honestly say you’d have to spend a LOT more money to get this kind of sound from the likes of NAD, Rotel, etc.  it doesn’t have some of the bells and whistles of some units. I didn’t care. I wanted great sound and that’s what I got.

    Rated 5 out of 5 by from I love it Bought it for my kid's room. Checked it with my RP-280F and her KSB 3.1, both sound very convincing. Built-in DAC is better than one in my older cd6005 unit. Daughter likes the appearance. Happy with the purchase.
