Xs Pre前级放大器在外观设计上也有变动,目前硕大的旋钮显得充满质感,更令到Xs Pre前级整体的感觉更具时代气息,我们知道,由PassLabs总裁的Desmond Harrington一手设计的音量衰减调控系统非常出色,这次Xs Pre前级使用的音量衰减调控系统同样先进,在机身上使用的是DallasDS 1882音量控制芯片,面板上的音量控制旋钮,是以光学耦...
Noise levels have been dropped from the already low-noise XP30. Refined circuit design and layout, new gain-stages with auto-bias and DC compensation all combine for optimal performance. But it all comes down to sound; once you listen to the Xs preamplifier, there is no going back....
the Xs Preamp has the ability to compete with any tube or solid-state preamp in the market from virtually any perspective. Tube lovers will either rejoice or curse but I strongly believe the challenge has been answered. The bottom line is that this preamp is quite unique...
At the same time, as Nelson Pass makes it clear in the Pass literature on the Xs 300s, they are not an exercise in size for size’s sake or in specmanship. He stresses the harmonic structure of the Xs 300’s transfer curve and its ability to reproduce the quality and integrity of l...
The Xs Preamp weighs 80 pounds versus the 108 pounds of the XA30.8 amp. When you consider this weight is divided between two chassis, it was much easier to unpack and install. When my UPS guy knocked on the door, I said, “I’ll go open the garage door, I know you have two big...
The gain circuitry continues to use our favorite transistors from Toshiba but has a larger higher biased output stage similar to the XS preamplifier auto bias. This makes longer and multiple cable runs easier to drive and gives us the advantage of simplifying our single ended output circuitry whi...
目前的旗舰Xs Pre电源分体前级 甲乙类输出的X系列后级,外观与XA系列一模一样 INT-250合并功放(输出甲乙类功率250瓦),是Pass Labs的入门产品一头披肩白发的帅帅老爷子,每年还会参与在旧金山湾区举行的Burning Man聚会,以及附近Sebastopol举行的Amp Camps和Speaker Camps。Burning Amp由 DIYAudio论坛主办,在旧金山举行,每...
Pass 现在的产品线，大概兵分三路，一是电源分离的 Xs 系列，然后是 Class A 放大的 XA 系列，再来就是大功率 Class AB 的 X 系列，而三部综合功放，则是后级加上前级线路的延伸，X250.8 衍生出 INT-250，XA60.8 衍生出 INT-60，至于 INT-25，就是以 XA25 为基础，加上 INT-250 与 INT-60 前级...
