Diva's lineA的品牌故事
Diva's lineA由韩国知名服装设计师买手金允聪自主设计创办。其早年在韩国做服装设计师、搭配师、服装买手，她常常自己动手去纺织,织布,鸡毛,纸,橡胶,塑料等所有可用来织成衣料的东西他都要去尝试,去探寻各种可能性。由于父亲是中国人，母亲是韩国人，从小就接触中韩两国的文化底蕴和穿衣风格。所以设计出来的服装风格独特。于2010年3月创办了独立设计品牌Diva's lineA。
b丝音响和啊家米丝音响有啥区别
音响线和普通线到底有什么区别，说法不一。但制造工艺是是有区别的。实事求是的说，花大价钱购买音响线（信号线和音箱线），不如把内部的关键器件换成高品质的。发烧信号线，不论是怪兽还是什么其他的大牌，一两米的价钱动辄几百，多者几千，但这些线比一般的线材（技术参数合格、价钱不超过几十块的）到底有多大差别，这个问题众说纷纭，评价的人多数是纯主观评价，带有强烈的主观倾向，心理作用在这些评价中起了主要作用。作为声音的评价，虽然不能避免主观因素，但可以利用比较经过严格的双盲实验来确定，下面是一份国外烧友的信，他进行了盲测，发现参加实验的人（这些人都是有经验的音响爱好者）无法区分线材的差别，甚至做不出正确的好坏判断，非常不可思议的是，参加实验的人都听不出用衣服架子（货真价实的衣服架子）做的信号线和怪兽线的差别。这个结果基本上证明了花大价钱购买昂贵的信号线材是一种盲目的行为，投资是毫无意义的，完全是被他人和自己忽悠了。当然，资金充足的人，满足一下自己的心理需求是无可厚非的。
转一封国外发烧友的信：
Dear audiophile;
In response to When is good enough, enough, （refering to hi-fi loud speakers） I think you missed the point after reading my epistle …but then again, maybe that's what I get for assuming readers will “read between the lines”.
A speaker is only good enough when it can duplicate the original sound it is duplicating with such a high level of accuracy that no measurement device, including the human ear/brain, can detect any difference between the original sound and the speaker's duplication of the same sound. Of course this is impossible with todays technology. Because of the fact the original sound must, in some manner, be converted to electrons which race down wires at the speed of light, which are resisted and capacitated which will always cause a difference between the original and replicated sound. Therefore, I ask the question, why strive for perfect replication if it is not doable? Further, since it is not currently doable, why should anyone labor over the concern of how accurate or “good” their speakers are, or in this case, when is good, good enough? What matters is if the speaker SATISFIES its owner with the clear understanding that the owner is not hearing anything remotely true to the original sound recorded on the replicating media.
A speaker is not a music reproducer because it cannot accurately reproduce the original sound of the music it is attempting to replicate. All a speaker can do is take what is fed into it electronically and produce a “resemblence” of the original sound. Therefore, a speaker should not be called a speaker, it should be called a noise, sound or “musical instrument”.
For the record, my first stereo speakers （noise makers） were Bose 901's （back in the 60's when they were the rage）。 From there I went to ESS Heil airmotion transformer A-1's, then the mighty corner Klipshhorns with center Belle Klipshorn, next came Theater Jensen A-5, then moving on to DQ-10-A's, then to Electrovoice 10-B's, then Martin Logan SL-3's and now a custombuilt $50,000.00 speaker system designed and built by Dennis Dean, Ph.D., an acoustical/audio engineer who fortunetly happens to be my brother.
Now let me tell you something about my home theater. My speakers （musical instruments） feature Scanspeak's slit-cone midrange Revlator drivers and matched silk dome tweeters （their best and most expensive drivers）。 The upper bass woofers are Daton Titanic III 10-inch drivers and the sub woofers are Daton Titanic III 15-inch woofers. The fs is 19 Hz and in their enclosure go down to 16 Hz at 125 dbs measured at one-meter （they rock the house when they achieve room lock）。 These speakers are 4-way tower floor standers. The cabinets are 2-inch MDF, braced, properly dampened, and stuffed with a proprietary filler. The weight is in excess of 375 lbs each! The center channel speaker uses the same tweeter and midrange driver as the left right towers. The center channel bass is channeled to the left-right tower woofers via the pre-pro （small speaker setting）。 The center channel also have two Revelator slit cone mid range drivers and the speaker is laid sideways on its own dedicated stand which places it dead center to the bottom of the movie screen. Cross over and phasing are set to eliminate lobing. The rear surround drivers use linium ribbons and 5-inch hexacone drivers with passive 24 db/Oct cross overs which are housed in a a nonresonate aluminum enclosures. These quasi omnidirectional speakers are ideal for surround speakers. They are mounted 7 feet from the floor on the sides and rear of the theater seating area. They are set on the small speaker setting in the prepro, thus utilize the left and right front main speakers woofers for bass below 80 Hz. They, along with the center channel speaker are crossed over at THX's recommended 80 Hz point. The sub woofer consist of a custom built 450 pound enclosure, tune ported per computer analysis which sports two 18-inch drivers. It works down to 12 cycles （- 3 db point which is the limit to our measurement equipment）。 Its efficiency is 95 db at 1 meter, 1 watt in put. The drivers are made by Focal （Jm Labs） in France. All speakers are padded to a 90 db output at one meter. All speakers are electronically crossed over and triampliefied with Anthem amplifiers @ 200 watts per speaker （each speaker has its own dedicated amplifier）！
My home theater pre-pro is a RDC-7 Integra Research （latest model with all upgrades）。 My DVD-CD player is Sony's flagship NS999ES DVD/CD/SACD player. Inter connects are Monster M-1000's wires. Speaker cables are good old fashioned 14 gauge Belden, oxygen free copper wire for the tweeters and midrange drivers and 12 gauge for the woofers and subwoofers （more about that later）。 My video consist of an 84-inch Stewart Grayhawk electric retractable screen. The overhead-front projector is a Sony Hi-Def LCD Cineza （the only dront projector I have ever viewed that projects a picture which looks good when an end table lamp is turned on in the room）。 I use Monster's line conditioner powered by a TripLite power converter transformer set up. All AC lines are dedicated 20 amp and grounded with a 3-foot copper stake in the ground. TV reception is DSS satellite. All Inter connects are 2 meters or less in length. Speaker wires are 18-ft. or less. My room is 12-feet high, 18.5 feet wide X 23.5 feet long and semi open to a hall, foyer and dining area （which make wonderful bass traps）。 This, mathmatically, causes a 34 Hz, 45 Hz and 72 Hz 5 db suckout, a mild 3 db suckout at 52 Hz and a huge 12db boost at 62 Hz and a 4 db boost at 80 Hz. This is corrected with an Audio control 1/6 octave bass equilizer （set with calibrated mic and meter）， plus judicious phase adjustment to the sub woofers. The bass frequency measurement while in the main seating area of the room （14-feet from the center of the screen） is + 2db, - 1.5 db from 120 Hz to 18 Hz. The entire system from 20 Hz to 11K Hz. （the limit to my hearing） is + or - 2.5 db @ 4.5 meters from the center speaker, while seated as measured on an HP real time spectrum analyzer. Acoustical treatment consists of hung decorator rugs on the back walls, large back wall book case stuffed with books and nic-nacks, an acoustical fluffed （popcorn） ceiling, a 9 X 12-ft. area rug, and very soft, absorbant, dual pleat blinds which may be dropped down on the side walls exactly where the first sound wave launch hits the wall. Speakers are properly placed by comuter and sound meter analysis.
One last thing regarding your comment on replication and judging the ability of
componants to bring you nearest the original sound （my words, not yours）。 I'm so sorry, but I do not buy into 90% of the hype brought to us audiophiles by the commercial sector of our hobby and the home entertainment industry at large. My brother, an audio engineering whiz kid has proven to me what is real and what is not. Let me rehearse with you an example of how he does this.
We gathered up a 5 of our audio buddies. We took my “old” Martin Logan SL-3 （not a bad speaker for accurate noise making） and hooked them up with Monster 1000 speaker cables （decent cables according to the audio press）。 We also rigged up 14 gauge, oxygen free Belden stranded copper wire with a simple PVC jacket. Both were 2 meters long. They were connected to an ABX switch box allowing blind fold testing. Volume levels were set at 75 Db at 1000K Hz. A high quality recording of smooth, trio, easy listening jazz was played （Piano, drums, bass）。 None of us had heard this group or CD before, therefore eliminating biases. The music was played. Of the 5 blind folded, only 2 guessed correctly which was the monster cable. （I was not one of them）。 This was done 7 times in a row! Keeping us blind folded, my brother switched out the Belden wire （are you ready for this） with simple coat hanger wire! Unknown to me and our 12 audiophile buddies, prior to the ABX blind test, he took apart four coat hangers, reconnectd them and twisted them into a pair of speaker cables. Connections were soldered. He stashed them in a closet within the testing room so we were not privy to what he was up to. This made for a pair of 2 meter cables, the exact length of the other wires. The test was conducted. After 5 tests, none could determine which was the Monster 1000 cable or the coat hanger wire. Further, when music was played through the coat hanger wire, we were asked if what we heard sounded good to us. All agreed that what was heard sounded excellent, however, when A-B tests occured, it was impossible to determine which sounded best the majority of the time and which wire was in use. Needless to say, after the blind folds came off and we saw what my brother did, we learned he was right…most of what manufactures have to say about their products is pure hype. It seems the more they charge, the more hyped it is.
So you see, my friend, that is why I have joined up with this site （audioholics） because their approach to good sound and education to acquire good sound and video is based on science, not hype, hypnotics, placebo effects or wishful
thinking.

line in 接口 和 line out接口的区别
Line in是信号输入，就是指将别的音源信号输入到电脑，如将随身听的声音输进去；
Line out是连接电脑音箱的。mic就是插麦克风的接口。
一般声卡拥有4大接口：LINE OUT（或者SPK OUT）、MIC IN、LINE IN和游戏杆（外部MIDI设备接口）。其中LINE OUT用于连接音箱耳机等外部扬声设备，实现声音回放；而MIC IN用于连接麦克风，实现录音功能；相比较而言LINE IN受重视的程度就不够了，其实它也是非常有用的。顾名思义，LINE IN就是线性输入的含义，与LINE OUT的功能恰恰相反。LINE OUT用于把经过声卡合成处理的声音对外输出，而LINE IN则是把外部设备的声音输入到声卡中。
LINE IN接口最为实用的一个功能莫过于把WALKMAN连接到PC上，这样就可以一边使用电脑，一边欣赏FM调频广播或是磁带歌曲了，够惬意吧。具体方法如下：到音响器材店花大约10元钱买一条双头3.5毫米插孔的音频连接线。将这条线一头与WALKMAN相连（插在耳机孔内），另一头插进声卡上的LINE IN插口就可以了。打开WALKMAN上的广播开关试一下，听电脑音箱是否传出广播节目声。
谈恋爱的步骤和过程？
1、互相吸引每一段感情的开始，都是从双方的互相吸引开始的。爱会让两个人变得有共同的兴趣爱好，共同的生活习惯，慢慢的让两个人变得越来越像对方，越来越接近彼此。2、依恋及思念互相之间会产生一种”分离焦虑“的情感，一旦某一刻见不到对方，就会感觉难受。渴望能够和对方在一起，慢慢的，双方会越来越依恋。3、接受对方的缺点有缺点没关系，毕竟大家都有一定的缺点，爱就是要学会包容和容忍，因为你爱一个人就要选择去爱她的全部。4、互相尊重不会去刻意的贬低对方，也不会去刻意的展示自己的优点。而是会互捧对方，眼中的他，和他眼中的你都是最优秀的。5、相处越久越感到幸福在生活中能够感受到对方带给你的温暖，从而面对生活也充满了动力，相处的越久越是觉得幸福。6、互相理解理解她的内心感受，她理解内心忧愁。偶尔的小吵小闹都会选择各退一步，还好沟通去解决问题。7、开始为对方准备小惊喜幸福的生活当然离不开偶尔的小浪漫，偶尔为对方准备的一些小惊喜，都会让感情迅速升温。8、开始互相融入对方的交际圈彼此之间的朋友圈互相熟悉，认识他身边的朋友，他也会去参加身边的一些聚会。双方的朋友也都会互相熟识，彼此祝福。
这个车，LINEA，有什么优点？
"优点：
1、1.4T的车，发动机到2500转感觉很好，贴背感比较强，发动机噪音非常小，关上车门几乎听不到发动机声音。
2、视野比较开阔，路感不错，德国蓝宝音响效果不错，大灯可调使用很方便，另外车上按钮设计基本都带阻尼手感也很好
3、空调比较强劲，经常只用1挡感觉就够了，免提蓝牙很方便，另外手套箱中带USB接口实际使用中也很方便，中央扶手2挡高低调节也很好
4、真皮方向盘以及挡头手感也相当的好，车子跑高速油耗很满意，大概在120公里左右6.7——6.8个油，市区不带空调要8个多点，综合油耗大概7.6左右，总体上感觉还行
