Allnic Audio 是来自韩国的发烧音响品牌，成立于2005年，公司主脑为朴康秀先生。
朴先生成立Allnic Audio 的目的，是为了达到甚至超 越Kondo 、Shindo 和Wavac 等公司的高度，制造出世界上最好的电子管 器材。
Allnic 这个名字来源于All Nickel 全镍磁芯变压器（又称坡莫合金 变压器）。
Allnic 公司认为，作为放大级的耦合器件，坡莫合金变压器 的高成本和制造难度是非常值得的，它能够高效率传输信号，并保持 动态和保真度。
所有Allnic 的电子管器材，都坚持使用自己制造的坡莫 合金变压器。
现场播放了张主编精心挑选的专辑曲目。
Audium 自然流畅的表 现，很好地诠释了Allnic 奥立、NuPrime 新派器材的细节丰富、动态极 大、背景宁静、声场极富3D 感的特点，获得在场发烧友的好评，大家 在活动结束后也与张主编进行互动交流，更加深入地了解奥立、奥笛 及新派更多的资讯。
音特网的总经理连泳华先生为大家介绍了这套本刊主编张戈先生与在场的发烧友分享不同类 器材的特点 型的音乐唱片11月3日，由三耳工作室策划的“尽探 蓝牙真高清’’主题分享会在广州东山口觉园 举行。
EAW 音箱技术参数
Avalon -- 娱乐场所系列DC系列DC 系列是为舞厅、夜总会等娱乐场所扩声而度身定制的高水准固定安装型扬声器系统。
低频部分采用双重或四重低音单元设计,产生了激荡轰鸣、震撼人心的节奏和效果，充分拓展并彰显了厚重的低音；中高频部分采用性能卓著的中频和高频单元，呈现同样出色的中高音音质，确保在整个中高频段、最大长期声压级情况下纯净、自然、水晶般清澈透明的音色。
DCS子系列为装载有号筒的超低频扬声器系统，用来强有力地增强低音效果.DCT子系列为用来进一步增强高音效果的超高频扬声器系统。

发烧音响有问有答
发烧音响有问有答问：请问Mission Pilastro报价。
用什么功放推？答：此扬声器的定价大概30万左右，建议用PASS LABS X350推，或者BRYSTON的4B、7B或者14B来推，也可以用MARK LEVENSON 4系列来推。
问：天仙配视频三线RCA有没有5米长的？价钱是多少？望给予回复多谢！！答：天仙配视频三线RCA线有5米长的，但需要订货，价格大约1万5千元人民币左右，详情请月国内代理广州保捷极品影音行联系，他们的电话是问：在下有几个问题请教。
现有器材:功放.马兰士pm-16;cd机.TEAC 20;音箱.AE100;全套超时空方心铜线材.听音广范,现想升级音箱,心意的有PROAC 50S,PROAC 2000S,B&W CDM 1NT..请推荐。
但关于马兰于PM-16功放,本人翻查了大量的音响刊物及上网查讯,却只有大量关于马兰士pm-14及pm-17的评论。
现请主持点评马兰士pm-16功放的声色,特点及与pm-14和pm-17有何不同？达到何等级别？另请推荐一台中低价位的LP唱盘。
望主持先生能抽空解答我的难题。
答：建议用PM-16推奥地利的维也纳的海顿扬声器，此箱的价格约8800元，或者选丹麦的SEK的S11，此箱价格约14800元。
这样的搭配比较合理，声音的表现也比较完美。
LP转盘可以考虑下美国的音乐教堂的唱盘。
问：请问BRYSTON 7Bst 和7Bst Pro ，BP-25前级的价钱，有现货吗？答：这套器材全部大概7万元左右，具体要与代理那边联系下才知道有没有现货，他们的电话是，。
问：本人想查询英国ATC音箱的中国(广州市)代理商是谁? 答：他们的代理的电话是，问：我于今年购得森海塞尔HD580耳机一副，望推荐耳放（国产，进口）及讯号线，现看中科颂U5及VHL 102D，不知此番搭配是否妥当。
另外，不知国产的滤波器效果如何望指点一二，平日喜欢听人声和小的作品，如钢琴、小号的小段，听感要求细节丰富，富有音乐感和层次感，对低频要求不高答：耳放可以用英国瑟顿SUGDEN或者意大利的BLUE NOTE的产品。
英特矽尔发表新数位音效处理
英特矽尔发表新数位音效处理
英特硅尔(Intersil)推出新D2Audio DAE-3HT 12-channel数位音效处理器和放大控制器，其具高效能与成本效益特性，符合消费者对音响系统的高音质音响要求。
并已于2012年国际消费性电子展(CES)展示其数位音效引擎(Digital Audio Engine)处理器和放大器技术。
DAE-3HT是特别为重视价格的条型音箱(Sound Bar)与蓝光家庭剧院系统提供高品质音响而设计，可接受多达八个数位输入声道和支援多达十二个脉冲宽度调变(PWM)输出讯号，以驱动Class-D功率放大器。
这款系统单晶片(SoC)采具成本效益的七十二接脚QFN封装，提供弹性的系统介面，包括四个I2S输入、一个I2S输出、S/PDIF输入/输出、I2C埠和串列周边介面(SPI)埠。
此外，DAE-3HT相容于Audio Canvas III设计工具，支援开发客制化的音讯路径组态，包括支援D2Audio SoundSuite音讯路径强化与虚拟化。
十二个PWM输出各提供整体音讯效能，以驱动包括功率与小讯号输出。

宽松自然欧博solo12寸音箱
欧博出品的Solo音箱使用12英寸同轴单元，其基本设计理念来自于同轴扬声器的大家老天朗的“监听”同轴音箱。
老一代的天朗同轴监听音箱以细腻的音质和华丽的韵味令玩家们爱不释手，当然这也是迷恋号角的烧友梦寐以求的，如今Solo则把这种浑然天成的声音传承了下来。
同轴扬声器的概念是高低音单元声音传送共享一条轴线，其物理定位接近于点声源，可以有效地优化扬声器轴线响应和离轴响应的对称性。
普通的多单元扬声器是无法实现这个对称性的，一般的分频音箱在轴线和轴线以外测得的相位响应是有很大差别的，而垂直角度的离轴响应就偏差更大，轴线以上和轴线以下单元之间的相位响应甚至是相反的，而这种相位问题用被动分频电路来校正是十分困难的，另外多单元音箱的单元排列不但存在垂直距离，而且存在水平距离，分频器可以校正分频点附近的相位，即相对相位得到校正，使各个单元达到相对理想的重合，但离分频点较远的区域就无能为力了。
虽然绝对相位的偏差人耳对其并不太敏感，但仍然对声像和定位的精度产生影响。
而同轴结构则可以有效地解决这一问题，使信号之间完全同步，并在任何角度均可实现相对一致的响应特性。
在继承传统号角技术的基础上，欧博创造出将压缩高音波导与同轴低频同轴有机结合的独特产品，该同轴单元的低频锥面是高频波导的自然延伸，而高音声源则放置于低频号角锥面的喉点上，这使得高低音之间即在结构上进行了有机组合，相位起始点完全重合，又在电声参数上进行平滑连接。
既模拟了单振模声波辐射特性，又有效地控制了调制失真。
这样的新技术结合既提高了高频转换效率，也保证了优良的指向性。
位于单元中心的高音部分采用了特殊设计的双曲线号角，使加有空气负载的高音与低音锥盆的直接辐射实现良好的耦合，使高音成为低音锥盆扩展的自然延续，实现完整的辐射波，厂家介绍，这支SOLO单元的磁路是普通磁体，低音音圈为75mm铜线，双短路环；高音为44mm 铜包铝线，使用铝线是为了减轻质量，增加瞬态和高频延伸。

对耳朵好一点小评节奏坦克小夜曲iDSD
对耳朵好一点小评节奏坦克小夜曲iDSD【IT168 评测】要说的话，小编真正接触所谓PC-HIFI的时候可能还在上小学，那个时候的电脑可是不插一块声卡就不能出声的——虽然不知道从什么时候起这块必不可少的卡慢慢的就被集成到主板上，再也没人研究其所以然。
不过在二十世纪末一台PC还是奢侈品的年代，每一个部件都代表着科技与设计的结晶，声卡自然也不例外。
从最早的帝盟、创新、罗兰、雅马哈，到后来国产崛起的华硕老虎卡什么的，在那个PCI-E声卡还是必选项目的时候，这个小市场也技术革新不断，神作频频精彩纷呈。
然而到了今天似乎一切都是强弩之末——大量传统音频厂商用各种高价一体机/网播/DAC蛮横的分走了机内声卡败落之后“外置声卡”的Hi-Fi市场份额，而这些传统PC音频设备厂商则一直被过去的定位所困扰，有些坚持出着没人气也没销量的产品，有些则是产品线一砍/放弃民用市场，彻底不玩儿了。
也有那么一两家厂子，在各种试水之后终于找到了那个切入点，扛着十来年的技术积累与工厂底子直接杀进现在所谓“P C-HIFI”的地盘，稳扎稳打的获得了属于自己的份额。
当年国产PCI-E 声卡的两大巨头：乐之邦与节奏坦克就属于这类。
今天小编要说的正是节奏坦克一款各方面都颇具竞争力，玩法全面新颖硬实力也不俗的新品：小夜曲iDSD。
外形：工业风与性能至上的设计挺好的说起小夜曲iDSD的外形的话，先抛开那个仿佛十来年前老美工的祖传方案一般的包装盒不谈，开盒之后的东西还是让人比较满意的，至少看着质感十足，不LOW 不糙，也没有寨味儿或者东莞味儿，说是森海新出了个一体机我都信。
正面来看，两个切换输入/输出方式的按钮，一个大家都扎堆儿复古于是变得丝毫不稀奇的音量旋钮和两个耳机孔排的满满的。
材质上，黑色亚克力面板干净漂亮，要是么有那个iDSD的丝印字儿的话就可以说是简约性冷淡风的优秀设计了。
机壳铝合金一体成型，表面的磨砂电镀漆工艺还行，手感滑滑的，哑光反光也比较屌，不吃划痕也耐用。

八、警告：
在钻孔前首先要确定自己的设计方案布局。在煤气罐、液压气罐及电线 旁边工作时要特别小心。确保功率放大器正确安装，以免在发生事故的时候 对人体造成二次伤害。
为了获得良好的音响效果，请按如下步骤调节放大器侧面的增益旋钮。
1、 用 螺 丝 刀 逆 时 针 旋 转 增 益 旋 钮 到 最 小 。 2、 请 在 车 载 播 放 器 上 播 放 强 劲 的 音 乐 ， 并 把 音 量 调 节 在1 / 3位 置 处 。 3、 调 节 功 放 的 增 益 旋 钮 直 到 获 得 良 好 、 舒 适 的 听 觉 效 果 为 止 。 4、 调 大 车 载 播 放 器 的 音 量 直 到 声 音 开 始 失 真 ， 再 往 回 调 小 一 点 音 量 使 它回到没有明显失真的音量级。 5、 调 节 功 放 的 增 益 旋 钮 直 到 获 得 可 接 受 的 强 劲 声 压 级 。 6、 调 小 车 载 播 放 器 的 音 量 直 到 达 到 舒 适 的 听 觉 效 果 为 止 。
