使 用注意点：1）电源变压器不要空开，如果插电，一定要连上耳放主机，否则会损害变压器。2）每次聆听前提早几分钟开机热身即可，不要整天开着“热机”，白 白浪费电力和胆管寿命。3）原配的电源线插头是欧标的，插不进国标插座、美标插座的，必须“万用插座”才能插，千万注意这点。搞一个万用插座的排插吧。3 Y" c* m; x \$ ?3 S; t) L! r) n4 i
搭配建议：OTL设计的EarMax Pro耳放高低阻耳机都能取得良好的效果，特别是它驱动Grado耳机（如SR325、RS1）以及Sony耳机，在国外发烧友中已有定评。驱动森海hd580、hd600、hd650系列耳机也很能体现它的特色。* ]+ m7 |/ E% z9 m7 P- p
英国Gramophone《留声机》杂志对Earmax Pro的评价：
7 `, f0 C$ K( t' P, i6 K. @0 CSounding big, weighty and tremendously smooth, the EarMax cruises through the busiest orchestral climaxes, always sounding fully in control while being capable of huge low-down slam. True, compared with Naim and Little More, the overall presentation may sound a little laid-back at first, music sounding subjectively slow, but let yourself settle in the sound and quickly you become aware that it's other designs' emphasis on the leading edges of notes that accounts for this, and the EarMax is equially true to the source material. And to those who will have you believe valves mean bags of bloom but a treble that's rolled off up top, then a quick listen to the Glinka overture with its succession of clean, extended highs, may well have you trading in your transistor pre and power amps tomorrow.
* \. K# N7 w, BEarMax 耳放听感规模大、有重量感、而且异常顺滑，在乐队演奏最复杂的地方也表现出完美的控制，低频段有冲击力。是的，与Naim和Headroom Little More两台晶体管耳放相比，它的总体声音呈现初听有些内敛，音乐似乎感觉有些“慢”，但只要适应一段时间，你很快就会意识到其中的原因是其他耳放对声音 的“棱角”做了一定强调，EarMax其实同样对音源非常忠实。有些人可能告诉你胆机就是没高频，高频是切掉的，但只要听一下格林卡的“鲁斯兰和柳德米拉 序曲”，领略一下其干净通透的高频延伸，你可能马上就会生出这样的念头——明天就把晶体管前后级放大器都换掉。

In fact, it is with the Ruslan and Lyudmila, that the EarMax's strengths are most clearly defined. Strings retain all their attack, yet have greater fullness, the timpani pounds out yet gains texture and body, the bass has greater rasp, and cellos improve the extension down low. And, best of all, this is all set against a background rich in the sort of fine detail that simply eludes in the other amps in this group.
$ z7 ~% C" D ]. N事 实上EarMax耳放的优点在这部序曲作品中表现得非常清晰：弦乐的声音保持了其所有的瞬态，同时拥有很好的丰满度，定音鼓的声音敲击有力，也有质感和形 体，低音有出色的擦弦质感，大提琴群带来了更深沉的向下延伸的低音。特别值得一提的是，乐队声音的背景细节丰富得异乎寻常，本次集体耳放评测中的其他耳放 在这方面都无法比拟。

2 ^- t3 B8 I* F/ Q: Y4 F, sBut the EarMax impresses most with its presence. Whether it's the Mozart opera or the Schubert sonata, no amp here gives you the feeling of "being here" quite as well as this tubed tot. Add to that is effortlessnes, its ability to convey all the emotion behind a piece, and its striking looks, and you have a headphone amp to treasure.' Z- m" d. s: b4 o2 d
EarMax最给人印象深刻之处在于临场感，不管是莫扎特的歌剧还是舒伯特的奏鸣曲，测评中的其他耳放都无法象EarMax这样给人如此“就在现场”的感觉。此外还有它声音的轻松感、它表达音乐中蕴含感情的能力。这是一台值得珍爱的耳机放大器。 |
