Today, we are going to check out the new Luxury & Precision W2. It is a portable USB DAC with headphone AMP and is part of the company’s flagship W series. Portable DAC/AMPs like the W2 have been gaining popularity since it upgrades your smartphone’s or other compatible mobile device’s audio. It turns your smartphone into a HiFi/Hi-Res digital audio player similar to a dedicated DAP. Luxury & Precision has two variants, the W1 and W2. I only have the W2 here and based on what I have seen and read on some forums and social media, the hype of this product could be real. So if you are in the market for a portable USB DAC/AMP, check out my Luxury & Precision W2 review below.
今天，我们来看看全新上市的乐彼 W2。这是一款带有耳机放大器的便携式USB DAC，是该公司W系列产品线的旗舰款。像W2这样的便携解码耳放一体机已经越来越受欢迎，因为它可以提升你的智能手机或其他移动设备的音质水平，它把你的智能手机变成了一个近乎于纯HiFi/Hi-Res数字音频播放器。乐彼推出了两款机型，W1和W2。我这里只有W2，根据我在一些论坛和社交媒体上看到和读到的内容，这个产品高热度的舆论可能是真的。因此，如果你在市场上寻找一个便携解码耳放一体机，请看看我下面的关于乐彼W2的评价。
Luxury & Precision W2 Portable DAC/AMP Review – Features and Specs
Let’s start with some of the features and specs that we can expect from the W2 portable USB DAC/AMP. The W2 features two Cirrus Logic CS43198 DAC chips on a dual DAC configuration. Meanwhile, the W1 only uses one CS43198, and I guess that’s the main difference between the W2 and W1. The W2 is also built with high-gate-count FPGA for EQ processing; offering “professional sound effects” and “lossless EQ” on top of parallel processing DSP.
Luxury & Precision is using a low-power MCU chip for the operation of the W2. I do not know what is the exact model of the MCU used. But it has a separate MCU so that the USB decoder chip only performs data transmission. It also offers an overall signal-to-noise ratio of up to 131dB; resulting in a darker background that is said to be “on par with TOTL flagships without multi-tone problems”.
乐彼W2便携解码耳放一体机评测 —— 功能和规格
让我们先来看看W2的一些值得期待的特点和规格。它带有两片Cirrus Logic CS43198 DAC芯片，采用双DAC配置。同时，W1只用一颗CS43198，我猜这是W2和W1的主要区别。W2还采用了高门数的FPGA进行EQ处理；在并行处理DSP的基础上提供 "专业级音效"和 "无损EQ"。
乐彼使用低功耗的MCU芯片来操作W2。我不知道使用的MCU的具体型号是什么，但它有一个独立的MCU，所以USB解码芯片只执行数据传输。它还提供了高达131dB的整机信噪比，从而使背景更黑，这个信噪比表现 "能与最好的旗舰机相当，且没有多音问题"。
About the CS43198 DAC chip from Cirrus Logic:
The CS43198 is a next-generation, low-power audio DAC that provides a superior system-level audio performance without draining battery life. The CS43198 features a high impedance of 600 Ω, a 130 dBA dynamic range, a THD+N rating of -115 dB, and inter-channel isolation of >110 dB. A patented on-chip DSD processor supports up to DSD256 in direct mode to preserve audio integrity by providing non-decimating volume control with soft ramp, and 50 kHz filtering as recommended by Scarlet Book. Volume matching of the analog output levels and channel mixing enable a seamless transition between the DSD and PCM playback paths.
The company also boasts that the W2 portable DAC/AMP offers an output of up to 125mw @ 32Ω for the single-ended, and up to 230mw @ 32Ω for the balanced output. That’s almost twice the level of similar products according to the company. This is one feature that got me really intrigue – “0 noise floor”. Luxury & Precision claims that the W2 offers a high output but with a very low or 0 noise floor on a tiny circuit board.
Aside from the “0 noise floor”, the LP W2 offers “incredibly low distortion. The total distortion is said to be as low as 0.00012% @ 300Ω or 0.00048% @ 32Ω. That is even lower than the claimed distortion of the CS43198 DAC chip according to the company. I don’t know how Luxury & Precision was able to achieve that, but it sounds impressive indeed.
Luxury & Precision also claims that its W2 is the only USB DAC/AMP dongle that has SPDIF output. Not sure why you’d want to use a SPDIF for this setup, but it’s there. It’s also compatible with Android and Apple smartphones/tablets. Below is a diagram showing the multi-chip architecture of the W2. After that, let’s take a closer look at the product itself.
关于Cirrus Logic公司的CS43198 DAC芯片简介：
（此处略，原文摘自CS官网关于43198的介绍，可自行查阅：https://www.cn.cirrus.com/products/cs43198/）
该公司（乐彼）自称W2的单端输出高达125mw @ 32Ω，平衡输出高达230mw @ 32Ω。据说这几乎是同类产品输出水平的两倍。还有一个让我非常感兴趣的特点--"0底噪"。乐彼声称W2提供了一个高功率的输出，但在一个很小的电路板上还做到了极低或近乎于零的底噪。
除了 "0底噪 "之外，乐彼W2还提供 "令人难以置信的低失真"。据说总失真低至0.00012%@300Ω或0.00048%@32Ω。该公司称，这甚至低于CS43198 DAC芯片的标称失真度。我不知道乐彼公司是如何做到这一点的，但这听起来确实令人印象深刻。
乐彼还提到，W2是唯一具有SPDIF输出的USB解码耳放一体机。我并不清楚你会在什么情况下会把它设置成SPDIF输出，但这个功能就在那里。它还与安卓和苹果智能手机/平板电脑兼容。下面是一张显示W2的多芯片架构的电路图。之后，让我们仔细看看产品本身。
Packaging and Closer Look
包装与外观
The Luxury & Precision W2 came with a small rectangular hard box. We can see an image of the W2 at the front and some information about the product at the back. Unfortunately, there is no English translation of what’s printed at the back. Don’t worry, the manual (inside) has the English translation.
Inside the box, you get the W2, a USB-C to Lightning cable, a USB-C to USB-C cable, a USB-C (female) to USB-A (male) adapter, and some reading materials. I’m not sure why, but Luxury & Precision included a white cable. A black cable would have been nice to go along with the aesthetics of the W2. The included cable is about 13cm long or about 5.12″ inches from end to end.
乐彼W2是一个小的长方形硬盒包装。我们可以看到正面是W2的图片，背面是关于产品的一些信息。不幸的是，背面所印的内容没有英文翻译。不要担心，手册（里面）有英文翻译。
在盒子里，你得到了W2主机，一根USB-C转Lightning的线，一根TYPE-C转TYPE-C的线，一个USB-C（母）转USB-A（公）的适配器，以及一些阅读材料。我不知道为什么，乐彼标配的线是白色的，如果有一条黑色的连接线就好了，可以相对搭配W2的颜值。线从头到尾大约有13cm/5.12英寸长。
The LP W2 is a small portable USB DAC/AMP; measuring only 60mm x 22mm x 12.5mm and weighs around 22 grams. At the front portion, you can see the company’s name/logo, and on its left is a 0.91″ OLED display. You can’t see it from the photo above due to the lighting.
The company’s logo is also printed at the back on a carbon fiber sheet. I’m not sure if that’s a real carbon fiber or just a sheet of plastic that has a carbon fiber finish/look, but it looks cool.
乐彼W2是一款小型便携USB解码耳放一体机；尺寸仅为60mm x 22mm x 12.5mm，重量约为22克。在机身正面，你可以看到公司的名称、logo，在其左边是一个0.91英寸的OLED显示屏。由于光线的原因，你无法从上面的照片中看到它。
该公司的logo也印在背面的碳纤维壳上。我不确定这是否是真正的碳纤维，或者只是一块具有碳纤维表面/外观的塑料片，但它看起来很酷。
LP W2 Buttons and Ports
按键和接口
On its sides are three multi-function buttons. The shorter one is the “enter” button and the longer one is for the volume up and down or left/right buttons. On the right-hand side are the 4.4mm Pentaconn balanced output and 3.5mm single-ended output. The 3.5mm out also serves as the SPDIF output.
On the left-hand side is a single USB-C port used to connect the W2 to the source. The W2 cannot be turned on without a source since it doesn’t have an internal battery. Once you plug the W2 into a smartphone, it will turn on right away and this will lead us to the next part of the review.
在其侧面有三个多功能按钮。较短的一个是 "进入 "按钮，较长的一个是音量加减或左/右调节按钮。右侧是4.4mm Pentaconn平衡输出和3.5mm单端输出。3.5mm PO输出也集成了SPDIF输出。
左侧是一个USB-C接口，用于连接W2和信号源。由于W2没有内置电池，所以在没有信号源的情况下无法开机。一旦你把W2插入智能手机，它就会马上开机，这将把我们带到下一部分的评测。
Luxury & Precision W2 User Interface
The LP W2 has a simple menu and interface. It’s quite easy to operate but it can be a bit finicky since you are limited with three buttons to operate the W2. Once you plug the W2 into a smartphone or other sources, you will be greeted with a similar look below.
用户界面
W2有一个简洁的菜单界面，它相当容易操作，但可能有点棘手，因为你只能用三个按钮来操作它。一旦你将W2插入智能手机或其他来源，你会看到类似下图的样子。
How to check the L&P W2 Firmware Version?
Since the W2’s firmware is upgradeable, you might want to check the current version before upgrading. To check the W2’s current firmware, disconnect it first from the source. Press and hold the small button, and while holding it down, connect the W2 to your smartphone or PC. The current version will be displayed for a few seconds before it returns to the default screen.
如何检查L&P W2的固件版本？
由于W2的固件是可以升级的，所以在升级前你可能想检查一下当前的版本。要检查W2的当前固件，首先将其与源头断开。按住小按钮，在按住它的同时，将W2连接到你的智能手机或电脑。当前的版本将显示几秒钟，然后返回到默认屏幕。
EQ, SDF, Gain, and Digital Filter Menu
EQ、特调固件、增益和数字滤波器菜单
The LP W2 has eight main options, the first one is the EQ preset. To access these settings, simply hold down the smaller button and the “EQ” setting will appear. And simply press the small button again (don’t hold) to cycle through the different menu. To change the setting under a menu, use the left/right buttons to cycle.
In the EQ settings, you can choose from normal, game, movie, bass, jazz, classic, pop, and rock presets. I usually just leave it to normal, as I find it the most natural and pleasing output. For the SDF settings, you can choose from normal or Xelento.
For the gain settings, there are only two options – low and high. I usually just use low for sensitive or very efficient IEMs. And I use high for earphones that use dynamic drivers or hybrids, and for efficient full-sized headphones. After the gain settings, there’s the FLT or the digital filter. You can choose from Fast roll-off, Slow roll-off, Low Latency Fast roll-off, Low Latency Slow roll-off, and Non-Oversampling (NOS).
I haven’t gone deep dive into the different filters. But for this review, I use slow and low latency slow (LL Slow) since I also use and prefer Slow digital filter on my LG V40. Using the same digital filter gives me, at least, an apples-to-apples comparison. To be honest, comparing the digital filter is quite difficult (at least for me). It needs time, getting used to, and a headphone/earphone that is sensitive enough to pick up the minute and (very) subtle changes.
W2有八个主要选项，第一个是EQ预置。要进入这些设置，只需按住较小的按钮，就会出现 "EQ "设置。而只需再次按下小按钮（不要按住），就可以在不同的菜单中循环。要改变一个菜单下的设置，使用左/右按钮来循环。
在EQ设置中，你可以选择正常、游戏、电影、低音、爵士、古典、流行和摇滚预设。我通常只是把它留在正常状态，因为我发现这是声音最自然、最令人愉悦的音效模式。对于耳塞特调固件设置，你可以选择正常或榭兰图模式（译者注：目前最新固件已更新IE800s和SE846模式）。
对于增益设置，只有两个选项--低和高。我通常只对灵敏度很高的入耳使用低增益。而对于使用动圈驱动或混合驱动单元的耳机，以及高灵敏度的全尺寸耳机，我则使用高增益模式。在增益设置之后，是FLT/数字滤波器。你可以选择快速滚降、慢速滚降、低延迟快速滚降、低延迟慢速滚降和非过采样（NOS）。
我还没有深入研究不同的滤波器。但在这次评测中，我使用慢速和低延迟慢速（LL慢速），因为我也在我的LG V40上使用并喜欢慢速数字滤波器。使用相同的数字滤波器，至少给我一个同类同平台的比较。说实话，比较数字滤波器是相当困难的（至少对我来说）。它需要时间，需要习惯，还需要一个足够有揭示力的高灵敏耳机/耳麦来捕捉微小和（非常）微妙的变化。
SPDIF, Display, HID Key, and Tune
同轴、显示、HID键和乐调音
The next menu/settings are for the SPDIF, Display, HID Key and Tune. You have the option to turn on or off the SPDIF, it’s self-explanatory. Meanwhile, for display, you can set it to manual or automatic off. In manual mode, pressing the small button will turn off the display. Set it to automatic off if you want the display to, well, turn off automatically after a few minutes.
Now with the HID key, you have to option to control the volume using the W2 or independently. When the HID key is off, pressing the volume keys on the W2 will not increase the volume output of the smartphone or source. The volume is only increased on the W2. You can still, separately, control the volume (output) of the smartphone.
Whereas, turning on the HID key, the W2 controls the volume of the smartphone or source. When turned on, the volume on the W2 DAC remains at the last value it was set to. And pressing the volume up or down on the W2 only changes the volume on the smartphone. For me, I’d rather set this off, so that I can control the volume of the smartphone and W2 independently.
The last menu is the tune option. There are only two options here, Tune 01 and Tune 02. According to Luxury & Precision, Tune 01 offers a “gentle tune”, while Tune 02 offers a “refine” output. I find it difficult to distinguish the difference between the two tunes. I just set it to Tune 02, as it is the default and it felt like the “better” tune or tonality.
接下来的菜单/设置是关于同轴、显示、HID键和乐调音。你可以选择打开或关闭SPDIF，这是不言而喻的。同时，对于显示，你可以将其设置为手动或自动关闭。在手动模式下，按下小按钮将关闭显示。如果你想让显示屏在几分钟后自动关闭，就把它设置为自动关闭。
现在有了HID键，你可以选择使用W2或信号源控制音量。当HID键关闭时，按W2上的音量键将不会增加智能手机或其他信号源的音量输出，音量只在W2上增加，你仍然可以单独控制智能手机的音量（输出）。
而打开HID键，W2就能控制智能手机或信号源的音量。当打开时，W2 DAC上的音量保持在最后设定的数值。而在W2上按下音量，只能改变智能手机的音量。对我来说，我宁愿将其关闭，这样我就可以独立控制智能手机和W2的音量。
最后一个菜单是调音选项。这里只有两个选项，Tune 01和Tune 02。根据乐彼官方的说法，Tune 01提供了一个 "温和的调音"，而Tune 02提供了一个 "细腻向的”输出。我发现很难区分这两种调音之间的区别。我只是把它设置为Tune 02，因为它是默认的，而且感觉它是 "更好 "的调音或音调。
L&P W2 Impressions and Subjective Listening
Now let’s talk about the sound quality and characteristics of the Luxury & Precision W2 DAC/AMP. I wasn’t really into USB DAC/AMP dongles since I was not a fan of something dangling from my phone. But the reason why I got interested in a USB DAC/AMP is that my LG V40 is about 2++ years old now. I got this when it was first released in 2018, and the 3.5mm headphone out is getting loose. In addition, most (if not all) of the latest smartphones don’t have 3.5mm headphone out anymore. If they did, the sound is most probably rubbish or so-so.
I love the sound quality of the V40, thanks to its “quad DAC”. And I think there are no other smartphones that have a good audio quality (Hi-Res/HiFi) other than LG’s V series. I could be wrong though. Too bad they are now out of the mobile business and the V60 is the last of its kind. I need something that can help me with my media consumption without the need to use a dedicated portable DAP. Not to mention, there are a lot of things you can’t do with a DAP that you can do with a smartphone. So, I just need the smartphone functionality plus the audio quality of a dedicated DAP.
Also, when testing the W2, I am using Campfire Audio’s Solaris 2020 and Andromeda (2nd gen) earphones. These two IEMs are fantastic, with excellent detail, clarity, and tonality; especially the Solaris 2020. I highly recommend them and if you’re looking for the best or one of the best IEMs in the market, be sure to try them.
W2的印象和主观听感
现在我们来谈谈乐彼W2解码耳放一体机的音质和特点。我并不是很喜欢这种迷你型的USB解码耳放一体机，因为我不喜欢在手机上挂东西。但我对它感兴趣的原因是，我的LG V40现在已经有2年多了。我是在2018年刚发布的时候买的，3.5毫米的耳机口已开始松动。此外，大多数（如果不是全部）最新的智能手机都没有3.5毫米耳机口了。如果它们有，声音很可能是垃圾或很一般。
我喜欢V40的音质，这得益于它的 "四路DAC"，而且我认为除了LG的V系列之外，没有其他智能手机有良好的音质（Hi-Res/HiFi），不过我可能是错的。太糟糕了，他们现在已经退出了移动业务，V60是最后一个同类产品。我需要一些能够帮助我进行影音消费的东西，而不需要使用专门的便携式DAP。更不用说，有很多你用DAP做不到的事情，你可以用智能手机做。所以，我只需要智能手机的功能加上专业级DAP的音频质量。
另外，在评测W2时，我正在使用Campfire Audio的太阳神2020版和仙女座（第二代）耳机。这两款入耳非常棒，具有出色的细节、清晰度和音质；尤其是太阳神2020版，我强烈推荐它们，如果你正在寻找市面上最好或最好之一的入耳，一定要试试它们。
Does the Luxury & Precision W2 (Really) Have A “0 Noise Floor”?
I don’t have any other portable USB DAC/AMP to compare the W2 with. So, I am going to compare the W2 to my LG V40 instead. In the course of testing the W2, I wanted to answer some questions. Is the W2 better than the V40’s Quad DAC? Is it (smartphone+W2) better than an entry to mid-range DAP? And does it really have a 0 noise floor or (dead) silent background as the company claims?
Let me answer the last question first. Yes, it does have a dead silent background. I was quite impressed since I could not hear any background noise, unwanted signals, or interference coming from the V40 at all. It reminded me of my Opus#1S DAP, which also uses two CS43198 DAC chips in a dual DAC configuration. The Opus#1S has a dead silent background, and it was better compared to the Cayin N3Pro when it comes to background noise. The LP W2 is in a similar situation, where it has a (much) better or lower background noise compared to the Cayin N3Pro.
Despite having a “quad DAC”, the LG V40 doesn’t have a “0 background noise”. I can hear some static or hiss, but it’s very minimal especially when compared to other smartphones. The noise is almost unnoticeable, especially if you are not using a (very) sensitive IEM or earphone. But when using the W2 with the V40, that noise was (instantly) eliminated.
W2（真的）是"0底噪”吗？
我没有任何其他便携式USB解码耳放可以与W2进行比较。因此，我打算将W2与我的LG V40进行比较。在评测W2的过程中，我想回答一些问题：W2是否比V40的四路DAC好？它（智能手机+W2）是否比入门到中档的DAP好？它真的像该公司所说的那样具有0底噪声底或（死寂一般的）无声背景吗？
让我先回答最后一个问题。是的，它确实有一个死寂的背景。我印象很深，因为我根本听不到来自V40的任何背景噪音、不必要的信号或干扰。这让我想起了我的Opus#1S DAP，它也是两颗CS43198 DAC芯片的双DAC配置。Opus#1S有一个死寂的背景，与凯音N3Pro相比，它在背景噪音方面的表现更好。乐彼W2的情况类似，与凯音N3Pro相比，它的背景噪音（好得多）或更低。
尽管有一个 "四路DAC"，LG V40并没有 "0底噪"，我可以听到一些静电声或嘶嘶声，但与其他智能手机相比，它已经非常小了，噪音几乎是不可察觉的，尤其是如果你没有用（非常）灵敏的入耳或耳机的话。但当把W2与V40一起使用时，这种噪音（瞬间）就被消除了。
How Does the LP W2 Sound Like? Is It Better Than Some DAPs?
I haven’t listened to the W2 extensively yet. But it didn’t take long for me to have my answers for my first and second questions. Yes, the W2 is (way) better than the LG V40’s Quad DAC. It is definitely a step up and improvement. And, to be honest, it could be even better than some upper entry-level to mid-range DAPs in the market.
Its audio output is simply very clean. The sound is like being “distilled and purified” by the W2, removing unwanted noise or hiss. To my ears, the W2 sounds transparent and revealing. It doesn’t colorize or adds emphasis on any frequency. Instead, it makes the sound richer and fuller, perhaps making the audio a bit more energetic.
For comparison, when I listened directly to the V40, the audio sounds a bit lean or perhaps a bit anemic compared to the W2. But when I listened to the W2 (connected to the V40), the audio sounds much better. It’s like turning condensed milk into a full cream one, metaphorically speaking.
I also noticed that it has much better dynamics; the bass region responds better and can do deep. It also feels and sounds well-controlled and fast. I am using normal SDF with (low latency) slow roll-off and tune 02. Using Xelento gives a different experience. It’s somewhat smooth and sounds a bit warmer or perhaps more “intimate”. Pair that with Tune 01 and it gives a totally different experience and mood.
The LP W2 doesn’t offer any “artificial sound staging or 3D imaging”. There is nothing like that on the W2, but it does offer a certain level or degree of spaciousness and imaging. It does sound like it has a (very) wide sound stage, but the audio certainly doesn’t sound cluttered or compressed.
W2的音质是怎样的？它比一些DAP好吗？
我还没有全方位地聆听W2。但没过多久，我就对我的第一个和第二个问题有了答案。是的，W2比LG V40的四路DAC（明显）更好，这绝对是一个进步和改善。而且，说实话，它甚至可以比市场上的一些入门进阶级到中级DAP更好。
它的音频输出简直是非常干净，声音就像被W2 "蒸馏和净化 "了一样，去除不需要的噪音或嘶嘶声。对我的耳朵来说，W2听起来很透明，很有启示性。它不会在任何频率上着色或增加重点。相反，它使声音更丰富、更饱满，也许会让音色更具活力。
作为对比，当我直接听V40时，与W2相比，听起来有点瘦弱，或许有点“贫血”。但当我听W2（连接到V40）时，音质好了很多。打个比方，这就像把炼乳变成了全脂的。
我还注意到，它的动态效果要好得多；低频响应更好，能做到更加深沉。它的瞬态也控制得很好，速度足够快。我使用的是普通的调音模式，带有（低延迟）慢速滚降和Tune 02。如果切换到榭兰图调音模式，会给人一种不同的体验：它有点顺滑，听起来有些温暖，或者说更 "亲密"。与Tune 01搭配使用，会有完全不同的体验和情绪。
W2不提供任何 "假大空的声场或3D结像"，在W2上没有这样的东西，但它确实提供了某种水平或程度的空间感和成像。它听起来确实有一个（非常）宽阔的声场，但绝不杂乱或有空间压缩感。
Pairing and Power
Specs-wise, the Luxury & Precision W2 has a 125mW@32Ω for the single-ended output and 230mW@32Ω for the balanced output. I haven’t tested the balanced output yet since I do not have a balanced cable for my full-sized cans. But for me, I think the W2 is better paired with IEMs and earphones. It doesn’t have any problems driving my earphones, even the DD or DD+BA ones.
While it can drive efficient full-sized cans without any problems, you’ll have to set the gain setting to high and crank up the volume. Of course, it depends on what headphones you use. In my case, I tried Audeze’s LCD-GX and LCD-X (since I am also in the process of reviewing them). The W2 can drive them, but it drains my phone’s battery a lot faster. It’s expected since the W2 draws more power from the V40 to drive the headphone.
搭配和推力
从规格上看，乐彼W2的单端输出为125mW@32Ω，平衡输出为230mW@32Ω。我还没有测试平衡输出，因为我没有为我的全尺寸头戴配备平衡线。但对我来说，我认为W2与入耳和便携头戴的搭配更好。它驱动我的耳机没有任何问题，即使是推多单元动圈或圈铁混合耳机。
虽然它可以毫无问题地驱动单元效率较高的全尺寸头戴，但你必须将增益设置调高，并调大音量。当然，这取决于你用什么耳机。在我的使用情况中，我尝试了Audeze的LCD-GX和LCD-X（因为我也在评测它们），W2可以驱动它们，但它使我的手机电池消耗得更快。这是意料之中的事，因为W2从V40吸取了更多的能量来驱动耳机。
W2 + Full-Sized Cans Is a No Go For Me
Generally, I don’t prefer using a full-sized can with the W2. For the LCDs, the “planar magic” simply wasn’t there with the W2. When I use the LCD-X with a DAC/AMP like the Schiit Jotunheim, it sounded somewhat different. While the sound and volume are there, it simply feels or sounds “not right”.
Another example, I like the pairing of the Luxury & Precision P6 (R2R DAC) and the LCD-GX when listening to Metallica. Honestly, I was quite surprised with the pairing; and it made me listen to my favorite songs from Metallica (repeatedly). But when I listened to the same tracks with the LCD-GX connected to the W2, it sounded that it wasn’t pushed to its maximum potential. The experience was different and it felt like the “magic” is not there.
I am aware that the Jotunheim and R2R DAC on the P6 is on a different level, and are totally different animals. But I just think that using full-sized headphones with the W2 doesn’t give them justice. Now, the experience could be different for you. I’m just speaking based on my experience and the gear that I used.
Okay, for now, I’m going to wrap up this review and may update this in the future.
W2+全尺寸头戴对我来说是不可行的
一般来说，我不喜欢在W2上使用全尺寸头戴。对于LCD来说，W2的 "平面魔法 "根本不存在。当我把LCD-X与Schiit Jotunheim这样的解码耳放一起使用时，它听起来有些不同。虽然音质和音量都在那里，但它只是感觉或听起来 "不对"。
另一个例子，在听Metallica时，我喜欢乐彼P6（R2R DAC）和LCD-GX的搭配。说实话，我对这套搭配的表现相当惊讶，它让我不断听我最喜欢的Metallica的歌（反复听）。但当我把LCD-GX与W2接起来听同样的歌时，它听起来没有被推到最大的潜力，这种体验很不一样，感觉就像 "魔法”不在那里。
我知道Jotunheim和P6上的R2R DAC和W2不在一个不同的水平线上，是完全不同的物种。但我只是认为，用W2搭配全尺寸耳机并不能给它们带来公正。现在，你的体验可能是不同的。我只是根据我的经验和我使用的装备来讨论。
好了，现在，我要结束这篇评测了，将来可能再会更新。

Luxury & Precision W2 Review Conclusion
Overall, I think the Luxury & Precision W2 is an excellent and impressive portable USB DAC/AMP. Although it is too early for me to declare that it is the best of its kind; since I haven’t tested other USB DAC/AMP like the Lotoo PAW S1 or iBasso DC03/DC04. But based on my experience, it sounds like a dedicated DAP with a really low or no background noise and distortion. If I blind tested it and didn’t know that what I am listening to is via a portable DAC/AMP, I would think that I am listening to a DAP instead. That’s how good it is.
Most smartphones nowadays don’t come with 3.5mm headphone out anymore. And if they do, audio quality is usually crappy. So, depending on your use case or setup, I think you don’t have to buy an entry-level or (semi) mid-tier DAP. Your smartphone/mobile device paired with the LP W2 could be what you are looking for.
W2评测总结
总的来说，我认为乐彼W2是一款优秀的、令人印象深刻的便携式USB解码耳放。虽然我现在宣布它是同类产品中最好的还为时过早，因为我还没有测试过其他USB解码耳放，如Lotoo PAW S1或iBasso DC03/DC04。但根据我的经验，它听起来就像一个专业级DAP，背景噪音和失真非常低或没有。如果我盲测，我不会知道我正在听的是通过一个便携解码耳放发出来的声音，我会认为我正在听一台DAP，这就是它的优点。
现在的大多数智能手机不再有3.5毫米的耳机输出。即使有，音频质量通常也很糟糕。因此，根据你的使用情况或需求，我认为你没有必要购买入门级或（半）中档的DAP。把你的智能手机/移动设备与W2配对，可能是你正在寻找的东西。
Nitpicks?
Now, there are a few things that I would like to nitpick about. Given its asking price, I’d prefer to see a much better quality (black) cable included in the package. The included cables are okay and serviceable. But they look and feel cheap and could be a weak link in the long run.
The second is I wish there is or L&P add a “memory function” where you don’t have to cycle through all the menu settings. For example, I am comparing Tune 01 and Tune 02 (the last (8th) option from the menu). After a few seconds has lapsed, it will go back to the very first menu option which is the EQ settings. And you’ll have to hold and press and press again to get back to the Tune options. At least, with a memory function, it will remain on the last menu option.
鸡蛋里挑骨头？
现在，有几件事我想挑个刺。考虑到它的要价，我更希望看到包装中附赠一条质量更好的（黑色）线材。附带的原线质量还不错，可以使用，但它们看起来以及感觉上都很廉价，从长远来看，这可能是一个薄弱环节。
第二，我希望有或者乐彼后续增加一个 "记忆功能"，让你不必循环查看所有的菜单设置。例如，我正在比较Tune 01和Tune 02（菜单上的最后一个（第8个）选项）。几秒钟后，它将回到第一个菜单选项，即EQ设置。你必须按住、然后再按，才能回到Tune选项。至少，有了记忆功能，它将保持在最后一个菜单选项上。
Finally…
This isn’t a cheap product and it is priced higher than its competition. But I noticed that price is (very) different from the value when it comes to this (audio) hobby. L&P offers something better here that could tip the scales towards the W2’s favor. And when it comes to audio quality, the Luxury & Precision W2 certainly doesn’t disappoint.
写在最后...
这不是一个便宜的产品，它的价格比它的竞争对手都要高。但我注意到，在面向（音频）爱好者方面，价格与价值是（非常）不同的。乐彼在这次W2上提供了更好的东西，可以使最终的天平向W2倾斜。至于音质这块，乐彼W2当然不会让人失望。
功能特色：4.5星
声音品质：5星
设计与UI：4星
性价比：3.5星
概述
乐彼W2是一款具有USB-C接口的便携式解码耳放一体机。它采用Cirrus Logic公司的CS43198 DAC芯片，采用双DAC配置，提供高分辨率和高保真输出，背景噪音非常低甚至为零。对于没有耳机输出或有耳机输出但音频质量不佳的智能手机和移动设备来说，这是一个极佳的解决方案。
总评：4.3星
