读者评分：8.5分

The Luxury & Precision W2 is the latest USB-powered portable audio solution, the sequel to the W1, launched in 2020. The new design comes with FPGA chipset-powered equalizing technologies and a dual Cirrus Logic CS43198 decoding chipset which is doubled from the W1.

The S/N ratio for this dongle goes as far as 131dB, comparable with some flagship devices, and also has a few advanced implementations for a dongle. Rumors say that this is one of the best dongles ever made and the specs look unbelievably good, time to plug it in and check out what the W2 can do!

乐彼W2是最新的USB供电的便携式音频解决方案，是W1的续集，于2020年推出。新设计配备了FPGA芯片组驱动的EQ技术和双Cirrus Logic CS43198解码芯片，比W1增加了一倍。

这款小尾巴的信噪比高达131dB，可与一些旗舰设备相媲美，而且还拥有一些对小尾巴来说相当先进的配置。有传言说，这是有史以来最好的小尾巴之一，其规格看起来好得令人难以置信，是时候插上它，看看W2能做什么了!



TECH HIGHLIGHTS

SUMMARY

It is quite amazing to see how far these small dongles have come to rival entry or mid-tier DAPs. It is even more intriguing to see what Luxury & Precision will put on their flagship dongle, having in mind that they designed many higher-end DAPs.

The W2 packs in a lot of features in its ‘Doublemint’ size casing. When you compare the internals, you will actually see it is quite similar to some full-sized players.

It offers a dual DAC, low power consumption MCU, FPGA for DSP, discrete oscillators, separate power supply for amping and decoding. There is also a spdif output and a “Pop sound eliminating chip” which is probably a relay component.

On the machine you will find a 4.4mm TRRRS output alongside the 3.5mm jack, with full balanced support outputting a whooping high output for a dongle, measuring 230mw at 32Ω.

DAC

If you follow closely the decoding chipset technologies there is no way you could leave out the CS43198, a highly regarded chipset after the CS4399 which consumes very little power. The W2 uses a dual CS43198 implementation to also allow a balanced output architecture.

With high output up to 2V RMS and 130dBA dynamic range operating in a single chipset configuration, the W2 has good enough power to kick some big cans loud as well as hooking up to the speaker system with an RCA to 3.5mm cable, still sounding dynamic and clean.

Other features of the CS43198 include a patented on-chip DSD processor that supports up to DSD256 in direct mode and 50kHz filtering. In my own experience, it is quite a smooth-sounding chipset with clean treble. Depending on implementation it can also get really engaging and dynamic.
Most major lossy and lossless codecs are supported by the W2, pretty much all you would need. It is also plug-and-play on Android and iOS devices. The device is recognized instantly but you will need to install a USB driver for your Windows PC.

Switching between different file formats there is no clicking noise or pop sound, and everything is very smooth. If you decode using DSD the power drain is higher so the W2 will warm up slightly.

PERFORMANCE NUMBERS

The W2 amplification will output up to 125mW@16Ω load and 230mW@32ohm. For a dongle, the numbers are good but we will check if it really sounds powerful in the sound impression session onpage 2.

The THD performance measures at 0.00012% only, which is even lower than that specified by the chipset manufacturer and is comparable to some high-end DAPs. The result is a very very dark background, even very revealing. Sensitive IEMs will sound dead quiet while being sufficiently powered to sound dynamic and engaging.

While distortion is low it makes me wonder if the output and gain are weak but that is not the case for the W2. There is actually plenty of power, nearly doubling Lotoo PAW S1’s output by 2 times on 4.4mm output (120mW) at 32Ω.

With 230mW in the output, the W2 has meaty lows and breathes more air into more power-hungry IEMs. Personally, this is a very welcoming move but as you may have expected, higher power consumption is the trade-off and it is draining ~1% off my iPad pro every song I listen to.

With the level of output, I experienced and with a dual DAC inside this is acceptable and if you bring along a small power bank it should be totally worry-free.

技术要点

摘要

看到这些小尾巴已经发展到可以与入门或中档DAP相媲美的程度，真是令人惊讶。考虑到乐彼精密公司设计了许多更高端的DAP，我们更想知道他们的旗舰小尾巴会有什么功能。
W2在其 "绿箭口香糖"大小的外壳中装入了很多功能。当你比较内部电路结构时，实际上你会发现它与一些全尺寸的播放器构造很相似。

它提供了双DAC、一个低功耗的MCU、一块用于DSP的FPGA和一块独立晶振，以及用于放大部分和解码部分的独立电源。还有一个spdif输出和一个 "POP声消除芯片"，这可能是一个继电器组件。

在机身上，你会发现一个4.4mm的平衡输出口和3.5mm的单端插孔，w2支持全平衡输出，在32Ω负载时高达230mW，对于一个小尾巴来说是一个惊人的高输出。

DAC

如果你密切关注解码芯片技术，你就不可能漏掉CS43198，这是继CS4399之后又一个备受瞩目的芯片，它的功耗非常小。W2采用双CS43198的实现方式，也可以实现平衡输出架构。

在单芯片组配置下，W2具有高达2V RMS的高输出和130dBA的动态范围，有足够好的功率来驱动一些大头戴，同样的，还可以用RCA转3.5mm线把它连接到扬声器系统，听起来仍然很有活力而且声底干净。

CS43198的其他特点包括一个专利的集成DSD处理器，在直解模式下支持高达DSD256和50kHz的滤波。根据我自己的经验，这是一个听起来相当流畅的芯片，具有干净的高音。根据实际情况，它也可以变得非常具有吸引力、爆发出高动态。

W2支持绝大多数主流有损和无损编解码器，几乎是你所需的全部格式。它在安卓和iOS设备上也是即插即用。该设备可以立即被识别，但你需要为你的Windows PC安装一个USB驱动程序。

在不同的文件格式之间切换时，没有咔嚓声或爆裂声，一切都非常流畅。如果你使用DSD解码，耗电量会更大，所以W2会稍微升温。

性能参数

W2的耳放部分将输出高达125mW@16Ω负载和230mW@32Ω负载的功率。对于一个小尾巴来说，这些数据是相当不错的，但我们将在第2页的声音印象环节中检验它是否真的听起来很强大。

THD性能仅为0.00012%，甚至比芯片厂标注的理论值还要低，与一些高端DAP相当。其结果是呈现出一个非常非常黑的背景，甚至“过分裸露”。高灵敏度的IEM听起来会非常安静，同时又有足够的动力，听起来很有活力和吸引力。

虽然失真很低，但它让我怀疑输出功率和增益是否很弱，但W2的真实情况并非如此。实际上，它有足够的推力，在32Ω负载下的4.4mm输出，几乎是Lotoo PAW S1（120mW）输出功率的2倍。

基于230mW的高功率输出，W2拥有富有肉感的低频，并为更多吃电的IEM注入更多空气感。就个人而言，这是一个非常受欢迎的举动，但正如你可能已经预料到的那样，更高的功耗是它的副作用，我听的每首歌都会消耗我iPad pro的1%的电量。

以我所听过的耳机口水平以及内置双DAC的用料来说，W2的耗电是可接受的，如果你带着一个小型充电宝，应该是完全无忧的。



DESIGN

Consistent with Luxury & Precision’s design language you get a cool masculine form factor with an elegant refined finish The back panel makes use of a matte color carbon fiber, which has been seen before on other Luxury & Precision players.

For my own preference, this looks very cool like some exotic hand-built sports car parts. At 22g it is quite light in the hand and will not stress the cable when hanging outside of the pocket.

The design is very compact measuring just 6cm widest and 1.2cm thick, still very slim considering there is the huge Pentaconn 4.4mm balanced port within. The overall build quality and machining quality on both the body unit and cable parts are really well done and premium, and it does feel quite luxurious and precise!

The small 0.91″ Monotone LED screen sits on the heavily machined casing, which feels quite industrial in design. Despite the petite screen real estate, the font size is clear to read with all the display info legible and tidily arranged.

SPDIF OUTPUT

I don’t think I have ever seen another dongle with spdif output. However, this could be a useful feature if you want to listen to your music collection on your phone, hooked up with your desktop gears by SPDIF input.

When you are using some devices like new Macbooks or iPad Pro it will also be a nice adaptor that gives you digital output without the need to buy a cable with USB-C to bigger USB connectors, but of course, you will need to hunt down a 3.5mm spdif cable for your setup.

CONTROLS

With only 3 buttons the W2 can be operated easily and you could switch from different options within a few clicks.

By holding down the button on the right side you will gain access to the settings menu including gain, EQ presets, SDF profiles tuned for specific IEMs, and Tune profiles. You can also cycle between these settings by pressing the multifunctional button.

The volume button will let you change the settings with the experience fairly similar to adjusting a computer monitor, quick and easy.

设计

外观与乐彼一贯的设计语言相一致，你会得到一个很酷的直男风造型和优雅精致的外观。背板使用了哑光色的碳纤维，这在其他乐彼播放器上已经出现过。

对于我自己的审美而言，这看起来非常酷，就像一些异国情调的手工制造的跑车部件。它的重量为22克，拿在手里相当轻，挂在口袋外面时不会对线造成压力。

设计非常紧凑，最宽只有6厘米，厚1.2厘米，考虑到里面有巨大的Pentaconn 4.4mm平衡端口，仍然算非常纤薄了。机身和线材部分的整体做工和加工质量都做得非常好，而且很高级，确实感觉相当的豪华和精确！

小巧的0.91英寸单色LED屏镶嵌在精加工的外壳上，在设计上感觉相当工业化。尽管屏幕面积不大，但字体大小清晰可读，所有显示信息清晰可见，排列整齐。

SPDIF同轴输出

我想我从未见过另一个带有spdif输出的小尾巴。然而，如果你想在手机上，通过SPDIF输入口与你的桌面设备连接，来欣赏你的音乐收藏，这可能是个有用的功能。

当你使用一些像新款Macbook或iPad Pro这样的设备时，它也会是一个很好的适配器，为你提供数字输出，而不需要购买USB-C转更大尺寸的USB-A的转换器，不过，显然你将需要为你的设备寻找一个3.5mm端子的同轴线。

操控

W2只有3个按钮，可以很容易地实现操控，你可以在几次点击中切换不同的选项。

按住右侧的按钮，你就可以进入设置菜单，包括增益、EQ预设、为特定IEM调音的SDF配置文件和乐调音配置文件。你还可以通过按下多功能按钮在这些设置之间循环。

音量按钮将让你改变设置，其体验和调整电脑显示器颇为相似，快速而简单。



FEATURES

HARDWARE EQUALIZER

The FPGA chipset inside the W2 can process equalizing at a nearly lossless rate, allowing the tuning to be switched instantly and without causing extra distortion.

This is one very important feature that differentiates it from quite some other devices with equalizer options, which are normally done by software and will hinder sound quality. You can switch between the below equalizers settings. I would expect that Luxury & Precision will update the options via software updates later:

•        Classical (Class)
•        Jazz
•        Rock
•        Pop
•        Bass
•        Movie
•        Game

FILTERS

The DAC chip provides 5 onboard filtering settings and you can switch between these by holding down the multi-function button on the W2. The five options include:

•        Fast roll-off / Slow roll-off interpolation filter options.
•        In each option above, both low-latency and normal phase-compensation filtering options can be used.
•        Non-Oversampling (NOS) mode, which minimizes the internal digital processing.

SDF PROFILE

The latest firmware updates include profiles that maximize the performance with the SE846, ie800s, and the Beyer Xelento. With the SE846 on and switched to the corresponding SDF profile, the output sounds more controlled and expanded than the default setting.

This is definitely a great feature and I hope Luxury & Precision could consider allowing the import of user-defined profiles or adding different profiles for more IEMs.

特点

硬件均衡器

W2内部的FPGA芯片组能够以近乎无损的速度处理均衡器，允许即时切换调音，而不会造成额外的失真。

这是一个非常重要的特点，它区别于相当多的其他设备的均衡器选项，这些选项通常由软件完成，会妨碍音质。你可以在以下均衡器设置之间进行切换。我希望乐彼以后会通过软件升级来更新这些选项：

• 古典（类）
• 爵士乐
• 摇滚乐
• 流行音乐
• 低音提琴
• 电影
• 游戏
  

滤波
DAC芯片提供了5个板载滤波设置，你可以通过按住W2上的多功能按钮在这些设置之间切换。这五个选项包括：

• 快速滚降/慢速滚降插值滤波器选项；
• 在上述每个选项中，都可以使用低延迟和正常相位补偿滤波选项；
• 非过采样（NOS）模式，它将内部数字处理降到最低；
  

SDF（特调）配置文件
最新的固件更新包括各种特调配置文件，可以最大限度地提高与SE846、ie800s和拜雅榭兰图搭配的性能。当连上SE846并切换到相应的SDF配置文件时，输出音质听起来比默认设置更有控制力和延展性。

这绝对是一个伟大的功能，我希望乐彼可以考虑允许导入用户自定义的配置文件或为更多的IEM添加不同的配置文件。



TUNE MODE

There is also a “Tune” mode that allows you to switch between Tune 01 and Tune 02 profiles, which represent two different timbres. The Tune 01 mode has a more easy-going and relaxing signature and 02 sounds firmer and with more control.

It would be nice if there are more explanations on these features or else users may miss out on these tuning profiles that have quite a distinct impact on the sound output.

HID CONTROL

Tuning HID on it will allow you to control the volume on the host device and the onboard volume will stick to the volume before you toggle on this option. To have more fine steps of volume for sensitive IEMS I am not using this function but it may be handy for those who want to change the volume fast with heavier loads.

乐调音模式

还有一个 "乐调音"模式，允许你在Tune 01和Tune 02配置文件之间切换，这代表了两种不同的音色。Tune 01模式有一个更随和和放松的特征，而02模式听起来更坚定，更有控制力。

如果乐彼对这些功能有更多的解释说明就更好了，否则用户可能会错过这些对声音输出有相当明显影响的调音配置。

HID控制

打开HID KEY，你就可以控制主机设备的音量，而机身自带的实时音量将保持在你切换到这个选项之前的音量。为了让高灵敏度的IEM有更精细的音量调节格数，我没有使用这个功能，但对于那些想在更重的负载下快速改变音量的人来说，它可能很方便。



PACKAGING & ACCESSORIES

The packaging is rather straightforward, just a small box with two layers that fits the body unit and cable parts. Printed at the back are the specs and descriptions in Chinese, not really an issue since it is very easy to navigate on this small device.

Opening the box and getting access to the lower layer you will find two cables including the lightning cable for iOS and the USB C cable for Android devices. There is also a USB-A adapter for laptops and a user manual in English.

Some other manufacturers do not include the lightning cable in the package and require a separate purchase, so this package will work well for those who use iOS and Android devices at the same time.

包装和附件

包装相当简单，只有一个两层的小盒子，适合放置主机和线材。背面印有中文的规格和描述，这不是一个真正的问题，因为在这个小设备上非常容易浏览。

打开盒子，进入下层，你会发现两根线材，包括iOS的闪电接口连接线和安卓设备的USB C连接线。还有一个用于笔记本电脑的USB-A适配器和一本英文的用户手册。

其他一些制造商在包装中不附赠苹果的闪电口线材，需要单独购买，所以这个包装附件对那些同时使用iOS和安卓设备的人来说效果不错。
