Point.8系列放大器提供高功率，更少的阶段，较低的失真和较少的反馈。按照Foresthill中，总部位于加州的公司，单位准确地表示非常深沉的低音和高音延伸录制场地。

该系列由五个A类放大器和四个AB类放大器，四双通道和五个直板机型。双通道放大器包括X150.8时， X250.8 ， X350.8的和XA30.8 。单型号包括X600.8时， XA60.8的XA100.8的XA160.8和XA200.8 。其每通道的额定功率为30为双通道XA30.8 600为单通道X600.8 。
由通Labs的X.5系列自2006年放大器的启发，较大Point.8系列的输出级被设计成偏向更深入地进入了A级经营区域。它们的特点是大推拉A级操作系统信封低失真和普通的听力水平不错的扬声器控制。

A类放大器采用更高功率的MOSFET东芝（金属氧化物半导体场效应晶体管）比以前安培。 MOSFET是通常用于转换电压。那些在Point.8系列运行在其既定功能的一小部分。该公司还安装了许多比平常更多的MOSFET上最Point.8模型。该X250.8和XA100.8放大器每次使用56 ，而X350.8 ， X600.8 ， XA160.8和XA200.8车型每次使用72 。

通Labs还提高了放大器的前端，这房子的输入和电压增益级。每个9 Point.8模型具有前端唯一模制到其输出级的具体细节，以使9前端部的大小不同，电压，偏置电流，功耗，以及单端与推挽分布偏见。

这些改进产生直接耦合（ DC）是拥有非常高的稳定性，低失真，低噪声， 100 kHz的开环带宽和高输入阻抗前端。
该电源也比那些更早放大器与第三多个存储电容，以及新的CRC（电容器 - 电阻器 - 电容器）过滤较大。该电源还采用并联快/从Plitron软整流器和大型环形变压器，但AC主电路都包含了额外的RF滤波。电源开/关切换和待机消耗也有新的。此外，通实验室改进超过10分贝放大器的输出噪声，并把放大器更耐变化的交流电源线。

较小的Point.8车型 - X150.8时， X250.8 ，该XA30.8的XA60.8和XA100.8 - 还配备了新的，更大的散热片来降低失真和消散较大偏差的能量电流。

Point.8 Series amplifiers deliver high power, fewer stages, lower distortion and less feedback. According to the Foresthill, Calif.-based company, the units accurately represent recording venues with very deep bass and extended highs.




The series consists of five Class-A amplifiers and four Class AB amplifiers, four two-channel and five monoblock models. The two-channel amps include the X150.8, the X250.8, the X350.8 and the XA30.8. The mono models include the X600.8, the XA60.8, the XA100.8, the XA160.8 and the XA200.8. Their per-channel power ratings range from 30 for the two-channel XA30.8 to 600 for the single-channel X600.8.
Inspired by Pass Labs’ X.5 Series amplifiers from 2006, the output stages of the larger Point.8 Series have been designed to bias more deeply into the Class-A operating region. They feature large push-pull Class-A operating envelopes for low distortion and good loudspeaker control at ordinary listening levels.




The Class-A amps employ higher power Toshiba MOSFETs (metal-oxide semiconductor field-effect transistors) than earlier amps. MOSFETs are typically used to convert voltage. Those in the Point.8 Series run at a fraction of their stated specs. The company also installed many more MOSFETs than usual on most Point.8 models. The X250.8 and XA100.8 amplifiers each use 56, while the X350.8, X600.8, XA160.8 and XA200.8 models each use 72.




Pass Labs also improved the amplifiers’ front ends, which house the input and voltage gain stages. Each of the nine Point.8 models has a front end uniquely molded to the specifics of its output stage so that the nine front ends vary in size, voltage, bias current, dissipation, and the distribution of single-ended vs. push-pull bias.




The improvements yield directly coupled (DC) front ends that boast very high stability, low distortion, low noise, 100-Khz open-loop bandwidths, and high input impedances. 
The power supplies are also larger than those of earlier amplifiers with a third more storage capacitance as well as new CRC (capacitor-resistor-capacitor) filtering. The power supplies still use paralleled fast/soft rectifiers and large toroidal transformers from Plitron, but the AC primary circuits now incorporate additional RF filtering. Power on/off switching and a stand-by draw are also new. In addition, Pass Labs improved the amplifiers’ output noise by more than 10 dB, and made the amplifiers much more resistant to variations in the AC power line.




The smaller Point.8 models — the X150.8, the X250.8, the XA30.8, the XA60.8 and the XA100.8 — also feature new and larger heat sinks to lower distortion and dissipate the energy of the larger bias currents.

我们很兴奋！因为我们庆祝我们第二十三年通过我们做过的最好的放大器。我们的新的8系列，x.8与XA。8，操作“高”为A和比以往桥梁测量性能和主观经验之间的差距。
 
用更苛刻的发烧友设计的发烧友，他们邀请听众的音乐是前所未有的。甚至，他们代表了我们的专业知识在设计放大器的总和，而优雅地表达我们对多个放大器的哲学，更进步和更多的音乐。
 
 
七年，8点系列表明我们相信最好的产品必须仔细调整，直到他们的成分协调运作-然后主观微调。用测量不满意，我们将放大器的最先进的工程通过广泛的，严格的听力过程中使用六种不同的音响系统，提供最高的音乐经验。
 
作为一个结果，该放大器与创新。例如，大点的输出阶段8放大器偏置 更深入的A级操作区域。他们更大的推挽A级操作信封提供在普通的听力水平低失真和附加的扬声器控制。高功率MOSFET，比平时多出许多，增加放大器的A类操作运行时其规定的规格的馏分以提高性能和可靠性。
 
还不满足，我们唯一成型的每个模型的前端的输出级的细节使九放大器的前端的大小不同，电压，偏置电流，功耗，单端与推拉偏分布。直接耦合的前端，所输入的电压增益阶段，最大限度地发挥每个模型的输出级的性能，同时赋予每个模型自身的微妙而独特的声波签名。
 
有更多的包括更大的电源供应，更多的存储容量，更精确的参考电压，和新的，更大的散热片，但我只想说，有点的8系列，我们超越了千篇一律的电路。

We’re excited! Because we’re celebrating our 23rd year by presenting the best amplifiers we’ve ever made. Our New Point 8 Series, X.8 & XA.8, operate “higher” into Class A than ever before and bridge the gap between measured performance and subjective experience.
 
Designed for audiophiles by even more demanding audiophiles, they invite listeners into the music as never before. Even more, they represent a summation of our expertise in designing amplifiers, while elegantly expressing our philosophy of more amplifier, more progress and more music.
 
 
Seven years in the making, the Point 8 Series demonstrates our belief that the best products must be carefully adjusted until their components operate in harmony — then subjectively fine-tuned. Not satisfied with measurements alone, we put the amplifiers’ state-of-the-art engineering through an extensive, rigorous listening process using six different sound systems to deliver peak musical experiences.
 
As a result, the amplifiers glow with innovation. For example, the output stages of the larger Point 8 amplifiers bias more deeply into the Class-A operating region. Their larger push-pull Class-A operating envelopes deliver low distortion and additional loudspeaker control at ordinary listening levels. And higher power MOSFETs, many more than usual, increase the amplifiers’ Class-A operation while running at fractions of their stated specs to enhance both performance and reliability.
 
Still not content, we uniquely molded each model’s front end to the specifics of its output stage so that the nine amplifiers’ front ends vary in size, voltage, bias current, dissipation, and single-ended vs. push-pull bias distribution. The directly coupled front ends, which house the input and voltage gain stages, maximize each model‘s output stage performance, while imparting to each model its own subtle and unique sonic signature.
 
There’s more — including larger power supplies, more storage capacitance, more precise reference voltages, and new, larger heat sinks — but suffice it to say that with the Point 8 Series, we move beyond cookie-cutter circuits.

体重较xa.5系列大幅增加

160.8和200.8现在什么价格？

频繁换款，不知是厂家的意思还是代理商的意思，如果是前者，代理商够累的

行货上市了吗？
