意大利设计师,实在是太牛逼了!这台极品后级放大器的声音给我的感觉就像保时捷跑车!他具有超级高速流畅而丰富的细节充满整个房间,声场自然的展开非常开扬,音乐的表达具有细腻的音符,低频具备强大的速度与冲击力,可以做到完全撑开的场面与动态,中性无染透明极致的声底,强大的爽快动态让交响乐气势磅礴,毫不拖泥带水诠释真实感,而中高音细腻,有力,自然。这是高素质的现代高保真之声,又保持了意大利的流畅乐感,与强劲的低频下潜与弹跳,他比起300到 400瓦的美国后级一点也不会在低频力量与厚度上吃亏,然而他超级潇洒的乐感是难以置信的,是欧洲顶级机器才具有的,本后级表现大编制交响,厚度,流畅性,声场规模还原一流,音色准确无比,具有高级别HIEND才有的一听惊讶的超级质感,他驱动庞大的单拿的小证据喇叭竟然让我听得赞不绝口!完全可以推好单拿小证据!强烈建议用家至少用它驱动单拿C2或C4,否则太浪费这台极品了。他驱动卡玛的DB9重量级喇叭也是轻而易举得到真实的声音。
下面为大家翻译一下官方介绍

The features of REVO PA-150 make it an extremely versatile power amplifier.
这是一台极致设计的极品后级
Its high power (140W/8Ohm,280W/4Ohm), the ability to drive the most demanding speakers and sound characteristics, make it unique.
超强的电源储备,达到8欧140瓦,4欧翻倍280瓦的强大输出。他有着能够驱动好最难推的大食喇叭的实力
Power, dynamics, speed and transparency are combined to make a total lack of listening fatigue and outstanding musicality.
能量,动态,速度,瞬态反应完美结合,造就完美无瑕的听感与杰出的音乐性。
But, also for people who want to combine it with other preamps, the REVO PA-150 can become a perfect partner. For example, with the best tube preamps you can enhance the characteristics of sound, giving an extraordinary ability to drive the speakers without introducing any harshness in the sound and the listening fatigue often present in solid state amplifiers.
如果你拥有一台电子管前级,与本后级组合,那么你将听到最自然的音乐。
The inside workings show that the technical refinement follow the same philosophy. The REVO PA-150 uses a proprietary circuitry, regulated high-speed power supply, low noise and is built with a careful selection of the best available materials.

本机为全平衡后级,左右完全独立设计,放在一个机壳内,平衡与RCA需要切换,这样将声音的干扰最大限度降低,通过平衡接口与RCA接口之间的开关进行切换,拨到平衡口这一边就是用平衡线,拨到RCA端子那一边就是用RCA信号线。
