转。罗技Z906和z5500全面比较(是英文版的）

hihgp

Year 2004 Logitech launched what was to become arguably the most successful 5.1 computer/home theater audio-system. At that time, Z-5500 was product ahead of its competition offering good sound quality, a slick design, plenty of power as well as versatility, crushing virtually all competitors on the PC consumer market. The system was, naturally, not flawless, weak spots existed, but the target customers received it with great appreciation, this being the reason for its huge commercial success. After seven years, during which it didn’t receive any major overhauls, Logitech announced a successor for Z-5500, namely Z906. In this article we tried to achieve a direct comparison between the two aforementioned products, we analyzed the pros and cons of the new model, and last but not least we tested its audio performance.

Presentation:
The first thing to meet the eye the moment we opened the box was the subwoofer. It was significantly smaller than that of the previous model, being lighter as well. After opening up both packages we started a direct evaluation of the two models

a. Satellites
Constructively, both model’s satellites are similar, both having used same 3’’ loudspeakers belonging to the “Full Range Paper Cone” series manufactured by Tangband. The speaker membrane is made of cellulose, the suspension of rubber, whereas the shape and volume of the housing is similar.

\
The audio output dissimilarities arise from the fact that Z906’s satellites are of the sealed type, whereas the ones from Z5500 are bass-reflex. The satellites have no tweeters, thus their only speaker unit must cover the whole frequency spectrum. We could not understand why such a solution was preferred, as it is clearly inferior to a classical, two-way solution with regard to the accuracy of the frequency response. Exterior-wise they they look different to a somewhat larger extent: the Z906 satellites lack the outer detachable mesh in favor of a fixed metallic one. They are also fitted with silicone rubber bumper feet instead of the rotating stand we have gotten used to in the previous model. The color of the plastic case is dark gray, which is more discreet than the shiny silvery tint used on the previous model. Both models have similar aesthetics as far as we are concerned, both plastic having a satisfying build quality. Z906’s satellites have a wall hanging system in case this is required; the cable-clutching system is firm. While we are not fond of this particular solution, we believe that it is acceptable for the system form factor.


b. Subwoofer
The differences between the two subwoofers are important, both construction- as well as functionality-wise. Both encasings contain the subwoofer own amplifier unit as well as the satellites’. In the case of Z906, however, inside the subwoofer casing lies the digital decoding module, unlike the Z-5500 model, where the DAC unit lied inside the exterior console. One other easy to notice aspect is the “evaporation” of the huge metallic heatsink that stood on the back cover. It is the aluminum-made back cover that overtook the heat dissipation task; we’ve tested the system up to high volumes and it never heated up to worrisome temperatures. On the back-cover of the subwoofer lie the system analog and digital connectors. Z906 features a generous amount of connectors, i.e. multichannel analogic input, stereo analogic input and three digital inputs(two tosslinks and a coaxial input).


We’ve opened up both subwoofers in order to study their design and components thoroughly. As one can notice from the pictures, the Z906 drags its juice from a SMPS (Switch-mode power supply) while the filtering capacitors are being rather small for the declared power output. We also believe that the finals (class D) on the integrated circuits are not the most fortunate solution. The Z5500, on the other hand, has a more solid amplification unit, with a larger toroidal transformer which is seated in the opposite corner with regard to the electrical parts, the filtration is more to our liking (2 pc. 10,000uF), the finals are of better quality and the massive heatsink insures an effective cooling.


The Z5500 subwoofer loudspeaker measures 10’’ diameter and is manufactured by Tangband, the model being WT644F. The Z906 subwoofer diameter is 8’’, significantly smaller than the previous model. Unfortunately, we could not identify its manufacturer and model, but it is likely to be aTangband W8-670Q. We apologize if we are wrong; the loudspeaker has no specifications printed on, being completely rebranded by Logitech, while the producer offers no official data regarding their product’s components origin

c. Central console, remote control, accessories
The Z906 central console has been simplified. On it, we could find the general volume knob, the individual satellites and subwoofer volume knobs, as well as the system configuration control (2.1, 4.1, 5.1, etc.). There is no longer an LCD, but only orange LEDs which indicate the status of the device, a much less elegant solution in our opinion. The horizontal layout of the console, the dark gray color of the system as well as the subwoofer’s smaller form-factor, all make this system easier to fit in a living-room, a feat we most definitely like. The remote control is simple yet very effective. The small dimensions and the ease of use make it pleasant and friendly to use. In this regard, we have only praise words: we could not understand why high-end receiver manufacturers do not include an EZmode remote control for basic menu access. We are increasingly being numbed by the lush and complicated high end remote controls, inappropriate for daily use.
The package also contains cables for the five satellites which are of questionable quality, being both thin and fragile. However we are glad to see that the user can change and thus choose cables according to his liking regarding quality, size and color, a feat we considered a strong point of the previous model that stills lies with the new one.
d. Digital to Analog conversion
The Digital to Analog conversion unit is completely overhauled. While Z5500 is equipped with Cirrus Logic (CS42526-CQZ DAC) chips, Z906 has AKM and D2Audio counterparts (AKM5386vt and D2-71583-L3). The aforementioned manufacturers are well-established, both AKM and Cirrus Logic being a good choice for quality.


TESTING:
We tested Z906 in parallel with Z5500, using both the analogic inputs as well as the digital ones. For the analogic input we used an ASUS Xonar D2 soundcard. As for the digital input we used the digital-coaxial output found on Xonar D2and the AD LABS MARS USB-to-coaxial interface.
Movies we watched:
• Burlesque (.mkv)
• Despicable Me (.mkv)
• Inception (.mkv)
Music we have listened to:
• Pink Martini – Sympathique (1999)
• CesariaEvora– Miss Perfumado [1992]
• Rihanna-Music.Of.The.Sun.2005
• Celine Dion-Best Ballads
• Francis Goya – Greatest Hits 2CD – 2009
• Dire Straits 1985-Brothers in Arms
• Chesky Records-Ultimate Demonstration Disc
 B&W-Demo
For gaming we used the exceptional Starcraft 2 as well as Crysis
At the end of the testing we performed a novel experiment. We linked together both system satellites to the Onkyo 807 “beast” in order to evaluate if and to what extent the audio-experience gets any better.
THE SOUND:
Z5500:
The Z5500 massive subwoofer shoots an impressive bass for a system of its price-tag. The solid amplification offers enough juice to the 10’’ speaker for the rendering of low frequencies. The bass we witnessed was ample and deep, lacking either outstanding precision or refinement, but being more than satisfying considering the target segment.
The middle frequencies sound cold, a feeling we’ve encountered the moment we listened to a few female voices. This downside penalizes the “live” sensation. The emotion an artist wishes to express is being lost.
The high frequencies are one of the system’s weak points. The lack of tweeters cannot be compensated by the full-range speakers, regardless of their build quality. The lack of resolution and details along the high-frequency spectrum is annoying and the listener misses important audio information.
When listening to music we could not achieve a satisfying tonal equilibrium. The bass covers the rest of the frequencies and dominates the scenery; we tried to reduce its volume selectively but we could only wind up with an absent, flat sound. There is a lack of coherence in the middle-low ranges, where there is a hiatus between the inferior middle spectrum and the bass.
As for watching movies and gaming we believed the system performed well, offering an enjoyable experience. The system possesses sufficient power and dynamicity to render a pleasant atmosphere, the spatiality sensation is vivid while the subwoofer raw strength brings in a specifically charming sensation, regardless if we consider a Playstation/PC game or an HD film.
The use of the ASUS Xonar D2 coupled analogically brings no significant benefits with regard to sound quality, certain details became more present, but to an insufficient extent so as to justify the investment if you own this system.

Z906:
Z906 has an aggressive bass which is lacking precision and depth. There were moments when it sounded uncontrolled, having a tendency towards humming and bumming. While watching films or gaming its swiftness confers a plus to the atmosphere while offering the necessary impact in order to make the listener shudder. Compared to Z5500, the Z906 bass cannot explore the very low frequencies, lacks depth, while being superior both in speed and aggressiveness. For films and games we preferred a fast bass while for music we considered Z5500s bass to be superior. Similar to Z5500, the subwoofer output has a tendency to cover the rest of the frequencies. However, in order to obtain a correct sound, we could manage a satisfying tonal equilibrium by playing with the system settings (which we could not obtain in Z5500).
The middle-range frequencies are very much similar to the Z5550, present but cold, synthetic, soulless. The only difference we could find between the two systems was a “thicker” sound envelope in Z5500, owed, most likely, to the bass-reflex encasing design.
The absence of dedicated tweeters is the great minus of this system. Despite numerous critiques received along the seven years of existence, Logitech decided to use the same technical solution of a full-range loudspeaker covering middle and high frequencies. We must admit the result is not overly disappointing (as one might expect at first glance), as the sound climbs up quite well in frequency. However we should reformulate two easy to spot problems: the system has an evident absence of details, which if manage to be squeezed out are being constantly covered by bass and middle-range frequencies.
The soundstage is mediocre for both models, a normal thing, considering that none of the two systems was designed for an audiophile stereo performance. As far as grinding is concerned, we have taken the Z906 out of the box and grinded it for 48 hours while the Z5500 had already been grinded for at least one year. We noticed no significant variation after the grinding period, as we listened to the system right after we’ve taken it out of the box for two days without long intermissions.
As with the Z5500, using the analog output of ASUS Xonar D2 brings no major improvement of the sound, so we once again do not recommend purchasing a superior sound source for this system.

We have also performed a novel experiment, coupling both system’s satellites to the massive Onkyo 807 receiver, being curious as to what extent are the satellites limited by the integrated amplifying module. We can sat it came as a surprise to hear the sound getting significantly better even for the untrained ear. The experience was indeed far from what we could easily achieve with our multichannel system based on Warfedale Diamond loundspeakers (which we own), but we could notice a clear quality increase at the level of details and dynamics, so we could conclude that the integrated amplifiers of these systems does not squeeze everything out of their speakers.
CONCLUSIONS:
If one year ago someone would have asked us what we would expect from Z5500’s successor we would have answered “dedicated tweeters, HDMI inputs, and decoders for the new hi-res (DTS-HD and DolbyTrueHD) formats”. Unfortunately Z906 brings NONE of the above mentioned feats, therefore we believe that Logitech missed an important moment, the moment it could have made Z5500’s successor a shining star of the PC/HT dedicated audio systems. On the other hand we suspect that the “lighter” amplifying unit design is meant to make the system more durable than the previous one and thus more appealing. It is thus a more stable, friendlier version of the Z5500 rather than a true upgrade.
PROS:
- Good performance in films and games
- Good connectivity and versatility
- Slick design
- Competitive price
- Ease of usage
CONS:
- The sound lacks any sort of refinement
- Lack of dedicated tweeters
- Lack of high definition decoders
- Severe lack of improvements compared to its predecessor Logitech Z5500
- Mediocre integrated amplification (bottle-necking the loudspeakers)
- Questionable quality cables (can be fixed)

其实这东西方还是不错的

2004年罗技推出后来成为可以说是最成功的5.1电脑/家庭影院音响系统。当时，Z - 5500产品未来的竞争提供良好的音质，华而不实的设计，充足的电源，以及作为通用性，破碎的PC消费市场上几乎所有的竞争对手。 ，自然，该系统并非无懈可击，薄弱点存在，但目标客户的好评与高度赞赏，这是其巨大的商业成功的原因。 7年后，在这期间，它没有收到任何大修，罗技宣布对Z - 5500的继任者，即Z906。在这篇文章中，我们试图实现了上述两个产品之间的直接比较，我们的新模式的利弊进行分析，以及最后但并非最不重要的，我们测试的音频性能。

介绍：
首先要满足眼睛的那一刻，我们打开了盒子，重低音扬声器。它明显比以前的型号更小，更轻，。开放这两个程序包后，我们开始了两个模型直接评价

A.卫星
建设性的，两个模型的卫星很相似，都使用相同的3英寸扬声器属于“全音域纸盆”系列Tangband制造。扬声器膜是由纤维素，橡胶悬架，而房屋的形状和体积类似。

\
音频输出异同出现的事实，Z906的卫星密封型，而从Z5500的低音反射。卫星有没有高音喇叭，因此他们唯一的扬声器单元，必须涵盖整个频谱。我们不明白为什么这样一个解决方案是首选，因为它是一个经典的，双向的频率响应的准确性方面的解决方案显然逊色。外观上他们看一个稍微大的程度上的不同：Z906卫星缺乏可拆卸外网赞成在一个固定的金属之一。他们还配备了硅橡胶保险杠英尺，而不是旋转的立场，我们已经习惯于在以前的模式。塑料外壳的颜色是暗灰色，这是比以前的型号上使用闪亮的银色色调更加谨慎。两款车型有类似的美学至于我们关心的是，无论是塑料有一个令人满意的建设质量。 Z906的卫星在箱壁悬挂系统，这是必需的;抓着电缆系统是坚定的。虽然我们不喜欢这个特殊的解决方案，我们相信制度的形式因素，这是可以接受的。


B.低音炮
两个低音炮之间的差异是重要的，无论是建设以及功能上。这两个encasings包含的重低音扬声器自己放大器单元以及卫星“。然而，谎言在Z906的情况下，重低音扬声器的外壳内的数字解码模块，不像Z - 5500模型，其中DAC的单位内外部控制台撒谎。另外一个容易注意到的方面是“蒸发”站在后盖的巨大金属散热片。它是铝后盖超越散热任务，我们测试过的系统，高卷，它从来没有令人担忧的温度加热到。在低音炮的封底谎言系统的模拟和数字接口。 Z906功能的连接器的大方量，即多声道类比输入，立体声类比输入和数字输入三个（两个tosslinks和一个同轴输入）。


我们开辟了两个低音炮，以深入研究他们的设计和部件。正如人们从照片上可以看到，Z906其汁，而一拖再拖，从一个SMPS（开关模式电源）滤波电容器正在小而宣布的输出功率。我们也相信，对集成电路的总决赛（D类）是不是最幸运的解决方案。 Z5500，另一方面，具有较大的环形变压器，这是坐在对面角落里的电气部件方面具有更加坚实的放大单元，过滤更合我们的胃口（2件。10,000 UF），决赛中有更好的质量和巨大的散热片，确保有效的冷却。


Z5500低音炮扬声器措施，直径为10英寸和制造Tangband，模型WT644F。 Z906低音炮的直径是8“，明显比以前的型号。不幸的是，我们不能确定它的制造商和型号，但它很可能是aTa​​ngband W8 - 670Q。我们深表歉意，如果我们错了;扬声器已印上不规范，完全由罗技更名，而生产商没有提供关于其产品的组件起源的官方数据

C.中央控制台，遥控器，配件
Z906中央控制台进行了简化。就可以了，我们可以发现一般的音量旋钮，个人卫星和低音炮的音量旋钮，以及系统配置控制（2.1，4.1，5.1等）。不再有一个液晶显示屏，但只有橙色的LED显示设备的状态，在我们看来优雅的解决方案少得多。控制台，暗灰色系统以及低音炮的体积更小的横向布局，都让这个系统更容易适合在客厅，我们最喜欢的壮举。遥控器是简单但很有效的。小尺寸和易用性是愉快和友好的使用。在这方面，我们只有赞美之词：我们无法理解为什么高端接收器制造商不包括EZmode基本菜单访问的远程控制。我们越来越多地被郁郁葱葱的和复杂的高端远程控制，不适合日常使用的麻木。
该软件包还包含了质量问题的五颗卫星，电缆，既薄且脆弱。然而，我们高兴地看到，用户可以改变，从而根据他的喜好有关质量，大小和颜色选择电缆，一个壮举，我们审议了以前的模式的剧照在于新的支撑点。
D.数模转换
数字模拟转换单元是全面整顿。虽然配备与Cirrus Logic（CS42526 - CQZ DAC）芯片Z5500，Z906 AKM和D2Audio公司的同行（AKM5386vt D2 - 71583 - L3）。上述厂家是行之有效的，AKM和Cirrus Logic公司是一个质量不错的选择。


测试：
我们测试的Z906，Z5500并行使用的类比输入以及数字的。对于类比输入，我们使用了华硕的Xonar D2声卡。作为数字输入，我们使用的Xonar D2and的AD实验室火星USB，同轴接口数字同轴输出。
我们看到的影片：
•滑稽（MKV）
•卑鄙的我（MKV）
•初始（MKV）
音乐我们听了：
•粉红马蒂尼 - Sympathique（1999）
•CesariaEvora小姐Perfumado [1992]
•蕾哈娜- Music.Of.The.Sun.2005
•席琳迪翁的最佳民谣
•弗朗西斯戈雅 - 最巨大的命中2CD - 2009
•恐惧海峡兄弟在1985年武器
•Chesky唱片最终示范光盘
B＆W - DEMO
对于游戏，我们使用的特殊的星际争霸2以及“孤岛危机”
在测试结束时，我们进行了一种新的实验。我们连在一起的两个卫星系统以评估是否和在多大程度上音频体验得到更好的安桥807“野兽”。
声音：
Z5500：
Z5500庞大的低音炮射击它的价格标签制度的令人印象深刻的低音。固体放​​大10英寸喇叭的低频渲染提供了足够的果汁。我们目睹的低音足够深，既无悬而未决的精度或细化，但满足考虑的目标市场。
中间频率的声音冷，一种感觉，我们所遇到的那一刻，我们听了几个女的声音。这样做的缺点惩罚的“活”的感觉。正在失去一个艺术家想表达的情感。
高频系统的薄弱点之一。不能得到补偿缺乏高音喇叭全音域扬声器，不论其建设质量。缺乏的分辨率和沿高频谱细节很烦人的，和听者错过重要的音频信息。
听音乐时，我们无法达到一个令人满意的音调平衡。低音涵盖了其余的频率和主导的风景;我们试图减少其体积的选择性，但我们只能缺席的，平的声音风。有一个缺乏连贯性，在中等偏低的范围，那里是劣质中间频谱和低音之间的间隙。
至于看电影和游戏，我们相信该系统表现良好，提供了一个愉快的经验。该系统拥有足够的权力和动态性，呈现一个愉快的气氛中，空间感的感觉是生动的，而低音炮原料的实力带来了一个特别迷人的感觉，不管，如果我们考虑一个游戏机/电脑游戏或高清电影。
使用华硕的Xonar D2加上类推带来音质方面没有显着的效益，某些细节成为更为现实，但不足的程度，以证明，如果你对自己这个系统的投资。

Z906：
Z906有一个积极的低音，这是缺乏精度和深度。有时刻它响起不受控制的时候，对嗡嗡声和流浪的趋势。看电影或玩游戏的同时，赋予其迅捷加分的气氛，同时提供必要的影响，以使听者不寒而栗。相比Z5500，Z906的低音不能探索非常低的频率，缺乏深度，而无论是在速度和侵略性的优越。对于电影和游戏，我们宁愿一个快速的低音，而音乐，我们认为Z5500s低音要优越。 Z5500，重低音扬声器输出有一种倾向掩盖其余的频率。然而，为了获得正确的声音，我们可以玩的系统设置（我们无法获得Z5500）管理一个满意的色调平衡。
中等范围的频率是非常类似的Z5550，存在，但感冒，合成的，没有灵魂。我们可以发现在两个系统之间唯一的区别是“加厚”Z5500的声音，信封，拖欠，最有可能的是，低音反射套设计。
没有专用的高音喇叭，是这一制度的伟大减去。尽管沿线存在的7年获得了无数的批评，罗技决定使用相同的全范围涵盖中，高频率的扬声器的技术解决方案。我们必须承认的结果是不是太令人失望（如人们所期望乍一看），声音爬上频率相当不错。但是，我们应该重新两个容易发现问题：系统中有一个明显的细节的情况下，如果管理被挤掉正在不断低音和中等范围的频率覆盖。
声是平庸的两个模型，一个正常的事情，没有考虑到这两个系统的高保真立体声性能设计。至于磨削而言，我们已经采取的Z906开箱和研磨48小时，而Z5500已经至少一年研磨。我们注意到，经过研磨期间没有重大的变化，我们听系统之后，我们已经采取了两天的盒子不长的中场休息。
与Z5500一样，使用华硕的Xonar D2的模拟输出带来的声音没有大的改善，因此我们再次建议不要购买此系统的出色的声源。

我们也执行了一种新的实验，大规模的安桥807接收机耦合两个系统的卫星，到什么程度是有限的卫星集成放大模块充满好奇。我们可以坐在它作为一个惊喜越来越明显更好，甚至未经训练的耳朵来听声音。的经验实在与我们Warfedale钻石loundspeakers（我们自己）为基础的多声道系统，我们可以很容易地实现，但我们可以看到一个清晰的细节和动态水平质量的提高，所以我们可以得出结论，集成放大器这些系统不挤一切扬声器。
结论：
如果一年前有人会问我们什么我们希望从Z5500的接班人，我们会回答“专用的高音喇叭，HDMI输入，并为新的高清晰度（DTS - HD和DolbyTrueHD）格式的解码器”。不幸的是，Z906带来了没有上面提到的功勋，因此，我们认为，罗技错过了一个重要的时刻，它可以Z5500的继任者一个专用的音频系统的PC /羟色胺的一颗耀眼的明星的那一刻。另一方面，我们怀疑，“打火机”的放大单元的设计是为了使更耐用，比前一个系统，从而更具吸引力。因此，这是一个更加稳​​定，友好的版本的Z5500，而不是一个真正的升级。
优点：
- 在电影和游戏的良好表现
- 良好的连通性和通用性
- 油滑的设计
- 有竞争力的价格
- 易于使用
缺点：
- 声音没有任何细化的排序
- 缺乏专门的高音喇叭
- 缺乏高清晰度解码器
- 改进的严重缺乏相比，它的前身罗技Z5500
- 平庸的集成放大（瓶缩颈的扬声器）
- 质量问题电缆（可以是固定的）

无名氏

Z680呢？

redeast

Z906使用数字功放，电源也采用开关电源，效率提高。技术上的进步降低了成本，提高了工艺性。所有信号输入端子都移到功放端，对信噪比的提高有帮助。

对于数字功放褒贬不一。

最大的郁闷是为什么我的Z5500的低音炮里没有吸音棉呢？看来要自己加了。

906和5500的低音炮结构还是有区别的，导向管都不一样，一个90度，一个是180度，不知道导向管对低音有多少影响
