这款新品马兰士HD-AMP1是一款高级紧凑型放大器，具有超凡、典雅、经典的外观。但不要让这些误导您，其高级开关放大器技术能迸发出“震耳欲聋”的70W功率（4欧姆负载时），其双晶体时钟和带有马兰士HDAM-SA2模块的分离式DAC后置滤波器能使标准计数的声音如高解析度音频一样令人吃惊。这款新功放还为您提供独特的Marantz Musical Digital Filtering (MMDF)技术，使用两个可选滤波器特性适应不同的品味和音乐。两者都能精心处理数字音频信号所包含的最微小的细节。因为当今的新媒体不仅有44.1kHz/16位解析度–（与CD格式类似），马兰士开发了数字部分以处理高达384kHz/32位解析度和DSD 2.8MHz / 5.6MHz / 11.2MHz的信号。 光纤和同轴数字输入已准备好连接电视机或机顶盒，还有一个USB-B端口，可从您的PC或MAC直接串流音乐。 还可通过前置USB端口连接iDevice。为在连接至计算机时保证质量，我们在USB-B输入端口周围强化隔离措施，以消除计算机所产生高频噪音进入HD-AMP1的机会。时尚的马兰士旋孔显示屏可显示音量、输入、解析度等信息。 前端是实心铝板，由双层底板和复古风格的侧板支撑。欢迎来到紧凑得令人心醉的世界。

Marantz MusicLink系列

马兰士再度借着MusicLink的再生加强其对纯音乐性能的投入，MusicLink产品系列于1990年上市，注重从小尺寸、罕见设计元件再现音乐的本质。目标很简单：为聆听者带来原始录音棚的所有情感和音乐细节，结合高雅外观和丰满的感觉。令人欣喜的新MusicLink系列的设计者又是Ken Ishiwata，这并非巧合。

马兰士音频性能及发烧级D/A转换器
不要被紧凑的外形误导。得益于超稳定电源以及马兰士独创的电流反馈技术，HD-AMP1可为4Ω负载提供2x 70 W的功率，可轻松处理哪怕要求更高的音乐部件。双晶体时钟以及带有该公司备受好评的分离式HDAM前置放大器模块和后置滤波器，使标准音频的声音如同高解析度音频一样令人吃惊。处理能力不低于384kHz/32位的高电流发烧级SABRE数模转换器，能够轻松地再现哪怕最小的细节。

独特马兰士音乐数字滤波(MMDF)
HD-AMP1具备参考级技术的独特马兰士音乐数字滤波(MMDF)功能。对于马兰士来说，使用标准数字滤波器解决方案不是一个选项，因为滤波对于数字输入信号的声音再现至关重要。因此，为了获得专家级技术，公司进行了大量投资，开发出备受推崇的Marantz Music Mastering技术，这一技术导致Premium Range 11系列获奖产品的产生。针对HD-AMP1硬件设计进行调适后，这种新型解决方案称为Marantz Musical Digital Filtering技术。两种可选的数字滤波特性以迎合不同的品味，两者都能精心处理数字音频信号所包含的最微小的细节，将新媒体文件转换成最精细的高解析度播放。

特殊的开关功放原理
HD-AMP1是马兰士首次利用开关功放原理的Hi-Fi产品。到目前为止，开关(D类)功放显示出一定的局限性，导致马兰士音响工程师不会考虑将其用于高级Hi-Fi产品。现在，HD-AMP1将马兰士独特的HDAM技术、开关功放原理与总体反馈环路结合起来，以保证各种扬声器具有一致的性能。与常规开关功放原理相比，HD-AMP1不会在功放模块的输出中提取反馈信号，而是在LC滤波级之后提取信号。若在LC滤波器之前提取反馈时，功放过程并不会考虑所连接的扬声器，因此，功放对所连接的扬声器的反应非常灵敏，其性能会发生变化。采用精心设计的开关功放并在LC滤波器之后提取反馈，所连接扬声器的影响就变得非常小。除了由功放输出阻抗决定的阻尼系数之外，所连接扬声器的阻抗对频率的反应也不太灵敏。功放原理的高转换速率以及高品质LC滤波器自身可确保较宽的带宽与平缓的频率响应。所有这些都通过紧凑的外形造就了超凡的Hi-Fi性能。

现代连接功能
HD-AMP1不仅构建在著名的马兰士音质基础之上，还具有极高的可连接性。光纤和同轴数字输入以及USB-B端口能让您从PC或MAC直接串流音乐，还可通过前置USB端口连接iDevice。为提供更多连接性，马兰士还附带两个模拟输入。USB-B以异步模式工作，不仅支持384kHz/32位高分辨率音频，还支持2.8MHz、5.6MHz甚至11.2MHz的DSD音频，使性能最大化，以最直接的方式欣赏极佳品质。为在连接计算机时能保证质量，马兰士在USB-B输入端口周围强化隔离措施，以消除计算机所产生高频噪音进入HD-AMP1的机会。

高品质耳机输出
针对通过耳机欣赏最喜欢的录音的音乐爱好者，HD-AMP1配备了高品质耳机级以及专用放大器模块HDAM-SA2。为了能与各种耳机配合，可从低-中-高改变增益因数。这样可以驱动低至高阻抗的各种耳机，不会有任何问题。

优雅的外观
毫无疑问，HD-AMP1是为听者耳朵提供的盛宴。其外形也很优美。前端是实心铝板，由双层底板支承，两侧的木装饰板颇有复古风格。时尚的马兰士旋孔显示屏可显示音量、输入、解析度等信息，体现了该公司最卓越的设计水平。这是纯手工工艺。

双层底盘和铝压铸隔离装置
HD-AMP1具有双层底盘，除主底盘外再加一块底板，以抑制外部振动对音质的负面影响。底盘的支脚采用铝压铸隔离装置以进一步吸收外部振动。

WHAT IS THE MARANTZ HD-AMP1?

This compact integrated amplifier marks the rebirth of Marantz’s Music Link range, which first emerged back in 1990 with the goal of delivering audiophile sound quality from small, elegant components.

It’s one of three products under the Music Link umbrella, alongside the HD-DAC1 headphone amplifier and £379 HD-CD1 CD player – the latter we’ll be testing with the HD-AMP1 and featuring in a separate review.

MARANTZ HD-AMP1 – DESIGN AND CONNECTIONS

It isn't every day we can say this about an amplifier, but the HD-AMP1 is simply stunning. Its design oozes elegance thanks largely to the gorgeous glossy side panels with retro wood-style patterning. These, combined with the rounded corners, give it a friendly, lifestyle look that won’t scare off muggles. There are two equally sumptuous colour options (Black and Silver/Gold), but the side panels are the same on both.

Don’t be fooled by its beauty, however – beneath the pretty surface lurks some heavyweight hardware. It’s housed in a dual-layer chassis with an additional bottom plate to suppress unwanted vibrations, supported by feet with die-cast aluminium insulators.

The brushed aluminium front panel plays host to Marantz’s signature porthole display, which shows the current input and the sample rate of the incoming signal when USB-DAC is selected. You get two large dials – one for volume, one for input selection – that turn with a smooth, firm action.

A few buttons are dotted about, including setup and standby, plus USB and headphone output ports. The USB port supports direct music playback from USB sticks and Apple devices, up to 192kHz/24-bit.

Rear socketry aims for quality over quantity, with premium-grade gold-plated connectors and Marantz’s chunky, solid brass SPKT-1 speaker terminals. There are two pairs of analogue inputs, coaxial input, two optical inputs, subwoofer output, USB-B and remote control in/out. Phono input is the only notable omission.

MARANTZ HD-AMP1 – FEATURES

The HD-AMP1 thumps out 70W per channel into 4ohms, or 35W into 8ohms, courtesy of Marantz’s HDAM-SA2 modules (employed in three separate circuit blocks) and Current Feedback technology.

Interestingly, it’s the first ever Marantz hi-fi product to incorporate a switching (class D) amplifier, which Marantz’s engineers previously didn’t consider acceptable for a premium hi-fi product. However, combining it with HDAM technology and an overall feedback loop irons out the problems, guaranteeing a consistent performance with a wide range of speaker types.

This HDAM technology is paired with a reference-class ESS SABRE DAC, which (via the rear USB-B port in asynchronous mode) can decode WAV, FLAC, ALAC and AIFF up to 384kHz/32-bit and DSD in 2.8MHz, 5.6MHz and even 11.2MHz.

Marantz Musical Digital Filtering (MMDF) uses proprietary filter algorithms to extract all the detail in hi-res tracks, with two selectable settings that cater for different tastes. The Dual Crystal Clock and a discrete DAC post filter ensure optimum digital-to-analogue conversion.

The elephant in the room is the lack of wireless connectivity. That means no Bluetooth, Wi-Fi, AirPlay, DLNA, app control or HEOS multiroom. If wireless is what you want, try Marantz’s £300 NA6005 network player instead – the HD-AMP1 is a more old-school affair.

MARANTZ HD-AMP1 – OPERATION

On the plus side, its simplicity makes the HD-AMP1 very easy to setup and control. Inputs are selected at the turn of a dial and tracks play at the touch of a button, not by sifting through menus on a smartphone. There’s something refreshing about that.

However, owners of Windows PCs hoping to use the USB DAC function will need to install the driver software (available to download from the Marantz website) and select the HD-AMP1 as their playback device.

The HD-AMP1’s large black remote sports a stripped-back array of responsive rubber buttons. At the top you’ll find keys for each input, while the playback, volume and menus controls below are well spaced out. The brushed black finish is attractive, too.

Use the setup button to toggle through the menu options on the porthole display. Here you can adjust the bass, treble and balance controls, select one of two filter settings and boost the headphone gain if you need to drive particularly demanding cans.

MARANTZ HD-AMP1 – PERFORMANCE

Marantz always strives for transparency from its products and that’s exactly what you get from the HD-AMP1. Playing a range of tracks across all inputs – all with the Source Direct mode engaged – it delivers an open and insightful performance, where every voice and instrument is rendered with outstanding clarity.

There’s an organic feel to the Marantz’s presentation. Some systems push the top end to engineer excitement; others overplay the bottom end for extra depth and impact. The HD-AMP1 does neither. It simply lets the music do the talking with a natural and well-balanced sound.

Most impressive is its ability to dig out fine top-end and mid-range detail. The Marantz sheds new light on elements of jazz compositions I thought I knew inside out; background noises, percussion patterns, guitar textures. It will breathe new life into your beloved classics, too.

Move to hi-res and the Marantz maximises the step up in quality, pulling out the extra sonic detail and turning it into something really rather beautiful.

But if the bulk of your collection is still of the standard-res persuasion, no problem. Paired with the HD-CD1, the HD-AMP1 makes CD-resolution material sparkle – during the perky jazz-funk of Lee Ritenour’s 'Bullet Train', the drums and slap bass are tight and focused, overlaid by rich, inviting piano riffs and sax solos.

And with George Michael’s Songs From The Last Century CD in the tray, the Marantz offers a sumptuous rendition of 'Roxanne'. Drums and vocals bristle with detail and it’s all gelled together by the solid double-bass and warm piano.

Next I gave the HD-AMP1 a workout with some fast-paced dance tracks. It conveyed the chunky basslines and busy kick drums with plenty of punch and agility. The system’s bass output is warm and seamlessly integrated, adding body without muddying up the mix.

What’s more, the Marantz creates a wide and immersive soundstage, with a clear idea of where instruments are placed. Shut your eyes and you’re whisked into the studio or live venue.

Despite its compact size, the HD-AMP1 is as comfortable driving large floor-standers as it is bookshelf or desktop speakers. I tried a few pairs I had lying around the house, from big Teufel and Tannoy floor-standers to Q Acoustics’ 7000i compact satellites, and it powered them all with aplomb.

With the larger speakers, it managed to convey the big dynamics of movie soundtracks at loud volumes without losing sight of the finer details. The amount of impact and poise on display here is terrific for such a compact and relatively affordable amp.

SHOULD I BUY THE MARANTZ HD-AMP1?

With its delectable retro design and gorgeous performance, the HD-AMP1 doesn't disappoint. It’s a versatile, accommodating amp, capable of driving a wide range of speakers and supporting any audio resolution you throw its way. Top-drawer electronics, clutter-busting dimensions and formidable build quality make that asking price seem thoroughly reasonable.

But its sparkling sound is the real story here. Transparency, insight, power and poise, the HD-AMP1 has it all, making your music shine, no matter the source.

In fact, the only bad thing I can say is that there’s no multiroom or wireless music streaming, but that’s scraping the barrel – as straight stereo amps go, the Marantz is a belter.

VERDICT

Marantz delivers the goods yet again with a stylish, sublime-sounding amp that redefines what compact components are capable of.

開聲試聽 聲音高貴溫

我們當日就在 76-FriendClub  的會址內, 用上店中一對書架式的 Cayin LYRE T50 來接駁這套靚仔西裝, 試聽了二隻唱片包括第一版張學友的《我與你》大碟及學而的LPCD版《be night back》, 當中都試聽了兩首歌曲, 以學友《只想一生跟你走》及學而《尋開心》, 以學友這隻唱片來講, 因為當年歐丁玉對唱片的要求都十分之高, 所以這大碟由這套西裝出來之感覺都非常正面, 首先音場非常廣闊, 開揚感非常之好, 而學友之男聲在一對 T50中間位置未算十分正宗, 這個相信需要多一點點時間作調校擺位有關, 而深度方面又未算十分明顯. 但幸好以這個大音壓來說整體音色都帶有一點馬蘭士一直以來的高貴及通透感. 而學而方面, 就同學友的原全相反, 音場窄了很多, 但深度竟然非常明確, 雖未至於可以看得見學而在場中唱歌, 但都可以找到多一點點的主體距離感來, 而音色方式這首歌因為是小瑟大王的喜好, 所以調子岩聽之餘更覺多一份份美感.

Conclusion : 「萬元的高雅品味之兩聲道入門組合」

實試了這套品味西裝之後, 雖然同上次6006 二兄弟的音色未至於有天與地明顯的分別, 但見其二位身形都非常細小, 本來都對其控制力及音色的平衡力有一點點懷疑, 但開聲之後, 反而覺得這對高雅西裝除了外型靚仔之外, 原來力水同原音性都非常不錯, 聽了二隻碟, 二隻碟的錄音取向都非常不同, HD-CD1+HD-AMP1可以完整地將二張大碟的錄音效果原整地呈現出來, 尤其是聽學而的尋開心時, 聽得大家都有一點點的回音醉意, 算是非常不俗. 雖然好多朋友都會說馬蘭士這套西裝及上次 6006 這二套西裝都不可以讀取 SACD , 有點不便, 但這個問題對於小火來說反而如釋重負, 因為小火到現在都是一張 SACD 都沒有, 主要都是買CD唱片為主, 而且多年來家中主要收藏的都是以 CD 唱片為主, 如果是希望聽更高質的音樂, 小火反而會考慮網絡串流播放會來得更有意思呢.
