The HPA-1 headphone amplifier was designed ground-up to become what we believe is one of the very best sounding headphone amplifiers available today. With low feedback, wide bandwidth and a direct coupled MOSFET output stage, this musical instrument drives even the most difficult headphone loads...
I haven’t even touched on the Pass HPA-1 as preamp in a simplistic setup. Without going into too much detail and making an already long review that much longer, I’ll simply say that the HPA-1 does just as well driving amplifiers as it does driving headphones. It’s transparent, neut...
Pass Labs擅长A类放大线路,HPA-1也是采取纯A类的放大。他们不在线路上取巧,也不是仅仅以加强增益或电压放大来推动耳机,他们也舍弃一切对声音没有帮助的多于设计,一切就是为了让HPA-1能够达到原厂对于声音纯净,以及强大驱动力的要求。 在源头部分就开始讲究,Pass LAbs认为电源供应的品质对于放大器影响甚巨,因此HPA-1...
History of Pass Labs repeats, and customers get more than what they pay for. The HPA-1 is priced as a headphone amplifier but it gives so much more. Every Pass Laboratories’ products are so very unique and differing even among themselves that, in my opinion, it is indicative of a fres...
Pass Labs表示,HPA-1可以轻易地驱动任何阻抗在15至600欧姆之间的耳机,尤其是难搞的静电耳机,HPA-1照样能制服的服服贴贴。一如其他Pass Labs的产品,机箱依然稳固结实,由经过阳极拉丝处理的铝合金板组成。有两组RCA模拟输入,还有一组RCA输出,因此,HPA-1也可视为一台前级。原厂甚至表示,HPA-1作为前级的表现,堪与...
and the subject of this review, the HPA-1 headphone amplifier, is the first Pass Labs product designed by Jam Somasundram, former director of engineering for Cary Audio. Somasundram joined Pass Labs in July 2013; he spent a year working on the HPA-1, which was shown at the2015 Consumer...
Headphone Amp HPA-1 Announcing the new Headphone Amp from Pass Labs! Like the XP preamplifiers, the HPA-1 is the result of great attention to detail. Starting at the power cord, the AC line is first filtered for high frequency noise and then isolated by a special toroidal transformer sh...
This story originally appeared at InnerFidelity.com Fig. 1: Pass HPA-1 amplifier, front panel Nelson Pass's Lab has produced an impeccable headphone amplifier with more than enough power, that's quiet, solid, and very clean. Several other reviewers have
off hours. We struck up a decades-long friendship that ultimately turned into a writing gig that has proved both stimulating and rewarding. In terms of music reproduction, I find myself listening more than ever for the “little” things. Low-level resolving power, dynamic gradients, shadings,...
求推荐一台1w到2...求推荐一台1w到2.5w之间的解码器,也可以是一体机目前二房passlabs hpa-1,求一个解码,目前用来推z1r,后期会上utopia,一体机也可以。个人比较喜欢有能量感的风格,如大乌那种口味,
