首先说明,本人不是玩家,只是普通的一个想弄一套不太差的音响看电影听音乐的最普通的消费者。因此不能指望我能听出音色有多细微的差别,当然如果刺耳或不对劲或不舒服还是知道的。
由于音响系统购买涉及线材、核心部件等多个东西,不能一次带回,所以这个报告可能需要多次才能完成和大家分享。
第一篇:在美国购买的器材列表及价格
Monster Cable Ultra THX 1000 Subwoofer Interconnect Cable (16 Feet), 中文其实就是一根16英尺的怪兽低音炮线,包括税价格是34.98美元
Monster Standard& THX-Certified Fiber Optic Digital Interconnect Cable (8 ft),怪兽8英尺的光纤音频线,包括税价格是24.95美元
Mediabridge - 15ft Ultra High Speed HDMI Cable - Version 1.3 Category 2 - 1080p-Blu-Ray - PS3 - W/Nylon Sleeve,15英尺1.3b HDMI线(线有尼龙套包裹,接头镀金),包括税价格是15.99美元
6 Feet HDMI Cable v1.3 Male to Male Digital A/V Cable, 30 AWG Cable, Gold Plated Connectors, Support 1080P True HD Resolution,三根各6英尺的1.3b HDMI线(接头镀金),包括税价格是8.77美元
MONSTER XPHPCIBIG100 100 Feet Speaker Cable,100英尺怪兽音响连接线,包括税价格是82.37美元
DELUXE 2000 WATTS HEAVY DUTY 110V/220V/240V STEP UP / DOWN TRANSFORMER FOR WORLDWIDE USE,Sirman 2000瓦的一个变压器,包括税价格是94.99美元
DELUXE 3000 WATTS 110/240V STEP UP AND STEP DOWN TRANSFORMER,Sirman 3000瓦的一个变压器,包括税价格是114.99美元
说明:以上价格包括运费,都是寄到美国同学那,然后自己带回国。最下面的三个东西我已经上次去已经带回来。那两个变压器真重,这也是为什么我得分批次才能把所有东西带回来的原因,要不收行李托运费就亏了。前三个刚买,得下次去美国才能带回。以上合计377.04美元

终于从美国把整套东西给搬回家了,好几个箱子,真累。幸好同去好几个同事,每人给我带一件,要不估计肯定被海关查。即便这样我自己带个大箱子还是被海关一个妹妹问了。我回答说是几个小音箱,美眉就让我过了。

目前还没有用,得等系统配置齐了才用得上。不知道这种稍微高级一些的音响是否要求也很高,之前从美国带回的两个箱子和一个带CD、收音及磁带播放的迷你音响反正用变压器完全没有问题,我就是按照功率给配了一个30W的新英的变压器。
上次从美国带回了两个大变压器,目前个人估计只要一个变压器就够了。原来想着给功放和低音炮各自配一个变压器的。

当时怕功率不够,也怕相互干扰或不利于位置安放,所以整了两台。等我确认两台都能正常工作,而且我一台够用,如果朋友的确有用,出你一台没问题。个人感觉这变压器质量非常不错。

本人烧得少,但自幼理科成绩超强,搜集资料能力算一流
来这里不久,潜水一阵,已经对坛子里的大虾有谁,各自风格与发言可参考度有了大致的底
玉米版是坛子里绝对的胆机权威之一,SPARK是他第三台胆了,欧博M100S-10他有,2A3,300B,EL34都玩得很熟,我相信他说的哈曼7500有胆味,不过HK970是否和7500音色一致就不知道玉版是类反出来的还是确有听过,总之,在没人说自己确实听过的情况下,还是得相信玉米版
但SMERT大侠又是坛子里另一高人,坛子里三大长老我以为就是DREAMCATHER,老玉米和SMERT了,另外还有一群尊者如J版,E版,达版等等,一些江湖怪人如庞兄,好死哥等等,当然还有些不太出世的高人我就不提了
此三位长老的发言对我等新手有非常大的影响力。虽然不尽信,但绝对是得考虑的。
我说的都是题外话,总之,我们是在高手的交流中学习了,这个话题的结论还请二位多费心了:loveliness:

谈点个人的看法,老玉米兄是AV199的版主,初烧一定会非常认真地考虑版主的建议。作为版主,推荐的产品的一些关键指标一定要准确,特别是对于初烧。电流量这个指标对于判断功放的推力有相当重要的参考价值 ...
我说的哈曼HK970的75安培输出电流是按照哈曼网站和说明书里给出的数据:
你可以不信,你有这个权利.
但我也有相信的权利.SMERT兄你认为呢?

不知道玉米兄除了斯巴克,是否听过其他胆机。斯巴克胆机的声音就是走晶体管功放的特点,类似的品牌还有德国Octave和Einstein。
欧博和声韵才是传统的胆机风格,美星、科宝和Melody属于现代派的胆机声 ...
SPARK A-70T是我的第三台胆机.
在买A-70T之前.我已经买了欧博的M100S PLUS(300B推挽机,已经使用快六年).欧博的CYBER-30(2A3单端,已经使用五年).还有一台十年历史的欧博胆前级QM-3.
三年才前买的A-70T.
所有这些胆机现在都还在家中.
除此之外:还有两种型号2A3,两种型号300B,各种型号EL34,KT88 九套(36只).4,5种不同品牌的前级小管.
我不敢说我对&胆机&了解,最起码我对欧博和SPARK胆机略知一二吧?

HK970的最大耗电量才345瓦,兄说HK970可能达到5000瓦的输出功率吗?线路版早就烧掉了。
提醒老兄一句:哈曼没有说HK970是5000瓦输出,这是你说的!
哈曼说HK970输出功率是70瓦,8欧!

我相信他说的哈曼7500有胆味,不过HK970是否和7500音色一致就不知道玉版是类反出来的还是确有听过,总之,在没人说自己确实听过的情况下,还是得相信玉米版
事情是这样的:
我的一个朋友买了哈曼HK970,当时我也很喜欢.就借来我家,与几个烧友听了.当时还与我的SPARK A-70T比较了一下.
印象很深,感觉很超值,我也想买一台.大家还劝我:&算了,你已经有A-70T了,HK970风格和A-70T声音完全一样,就是低频好点,等于花了钱就改善了一点低频&.
所以没有买HK970,但始终无法忘怀哈曼.才有了后来买的哈曼AVR 7500.
但尽管这样,仍需要声明一下:我在前面只是说我的AVR7500声音风格象胆机,因为朝夕相处,经常比较.
HK970我只听过,并未拥有.

至于SPARK的胆机究竟是否晶体管机器风格?这个问题很主观.每人都有自己的看法.我不想争论.也争论不出结果.
但没人否认SPARK A-70T是胆机吧?
从我个人体会,SPARK胆机速度比较快,动态很好.新机器声音不够细腻,有些躁,确实有点象不太高级的晶体管机器.
但是使用1-2000小时以后,声音变化很大.温暖厚润,动态凌厉.声音非常大气.
煲透以后的SPARK胆机与欧博胆机相比,声音风格确实有差别,但差别不是太大,至少不象有些人形容的那么严重.
应该说都是不错的声音.
个人观点,仅供参考!

哈曼卡顿970这样的指标非常不严谨,明显是误导烧友。
指标是否严谨,是否明显在误导烧友。我想这是哈曼公司的事情.
最起码老兄要承认我引用的哈曼HK970的指标没有错误.
不过我想:哈曼公司是一家50多年历史的老公司,旗下拥有众多音响领域的一流品牌,若是靠&指标非常不严谨,明显是误导烧友&。是不会生存到今天的.

我说的哈曼HK970的75安培输出电流是按照哈曼网站和说明书里给出的数据:
/specifications.aspx?Region=EUROPE&Country=CN&Language=ENG&cat=AMP&ser=&prod=HK%209 ...
既然这样说,小弟也无话可说,请烧友自行判断HK970是否能达到75安培吧。

小弟花了1个小时,看了玉米版主给的这些链接。除了哈曼品牌的功放外,其他的如Lexicon、Marke Levinson和Crown的功放都没有给出电流的指标。难道哈曼公司除了哈曼这个品牌外,其他品牌没有这个技术实力测试自己产品的电流量?那是不可能的事情。
偶承认哈曼集团是非常成功的音响企业,有着雄厚的技术实力和产品开发能力。哈曼HK970的这个75安培的指标并没有错,因为并没有标在什么样的状态下。但懂一点电学知识的烧友都知道,75安培的电流量意味着什么。
马兰士、安桥和天龙在AV功放领域都是很出色的生产商,大家也知道,一台最最入门的AV功放象天龙1403,都能达到120瓦×5的功率。这样的指标没有错,因为在日本人自己的JEITA标准下的确可以达到这个指标,但在功放常用的RMS标准下,最多也就是50瓦×5的水平。在这方面,哈曼做得很好,哈曼的AV功放标的都很实在,AVR745才标85瓦×7,但其推力明显比那些日系150瓦×7的AV功放大。所以日系的AV功放有误导的嫌疑,但它们一样生存得好好的。因此哈曼的功放在推力上都是足斤足两的,但不能以此就认为电流量指标也是足斤足两。
再举一个大家都知道的例子,诺基亚是世界级的手机生产商吧,诺基亚的手机都有待机时间这个指标,偶用过的Nokia 3108号称待机时间有100-250个小时。正常使用的话,待机从来就超不过3天,也就是72个小时。就算加一倍时间6天,也就是146个小时,还是远达不到250个小时。关键就在于工作状态,250个小时是不插sim卡的状况下计算出来的时间,而这个指标对于用户来说没有任何意义。

说实在话,我对SMERT兄非常尊重,这种尊重不是现在,而是原来在HIFI168论坛就有的.
但尊重不是盲从,所以我还是把自己的看法说出来了.
我从平时SMERT兄的帖子,知道老兄喜欢SIMAUDIO和EXPOSURE的产品.
但我觉得老兄可能是太喜欢了,所以有时把他们当成了衡量其它器材的标准.其实这些音响厂每家都有自己的设计理念,用电影里的话:&高家庄,赵庄,马家合子,各村的挖地道都有自己的高招.&
在我们无法自己测量他们的输出电流时,而又找不到别人的证明,有时不得不信厂家提供的数据.
也许就象哈曼公司自己说的:“今天,我们依然坚持三条关键设计理念来制造放大器。通过高电流,超宽频带,分立放大电路,达到稳定性、速度、低不可闻的谐波失真和互调失真。由这些特质共同制造的大功率乐音具有极好的透明度和清晰度,这也是哈曼产品的音质保证。”

我当时说75A还是很保守的.
说明书里还给出了另外一组数据,是降低一些信噪比(比网站给出的信噪比降低10分贝)的输出电流:80A.
Stereo Mode
Continuous Average Power (FTC) per Channel :& & 2 x 80W @ 8 ohms
动态功率:115瓦/8欧
Frequency Response (1W +1/-3dB): :& & 10 Hz -150 kHz
Signal-to-Noise Ratio (IHF-A) :& & 95 dB
High Instantaneous Current Capability (HCC) :最大输出电流:& & ± 80 Amps
阻尼因子:125

Power Requirement :& & AC 230 V/50 Hz
Dimensions

(指标是说明书里的,凭记忆,可能不准。与哈曼网站略有出入)
但有时不得不承认哈曼的产品有些自己的特点,要不为什么奔驰,宝马,劳斯莱斯等名车都是选择哈曼作为车内娱乐产品.

我只是引用的数据.我本人也觉得这些指标有些恐怖.因为我很少看到,有功放标出来1欧阻抗的输出功率.
但实际听,HK970确实驱动力十分厉害.我家里有一对唯美六,是三分频的皱皮纸单元大落地箱.灵敏度只84分贝.好象我的记忆里大落地箱只有它和ATC M40能低到84分贝.接上70瓦输出功率的HK970,推的很好.
我现在用的AVR7500.几项指标是其它AV功放里没有的:
⑴ High Instantaneous Current Capability (HCC)(高电流输出): 75 amps(安培)
⑵ Ultrawide-Bandwidth(超宽频带):&&10Hz – 100kHz
⑶ Slew Rate(转换速率):&&40 V/μsec
⑷ Rise Time(上升时间): 16μsec
推动84分贝的三分频箱子杰作唯美六游刃自如。大音量不脚软,称奇的是我经常很小音量听,声音也很平衡,尤其是低频控制很自如.
英国《home cinema choice》杂志对哈曼AV7500功放的实际功率测量结果:
Manufacturer's stated output(厂家标称功率): 100W (20Hz-20kHz, 8ohms, 0.07% THD)
Measured power output(实际测量功率) @ 1kHz: 152.5W (8ohms, &0.15% THD) 251.1W (4ohms, &0.10% THD)
文章说7500推B&W 800箱子都能很好.

7.1CH, 积分 7592, 距离下一级还需 408 积分
持续输出电流和瞬间电流有区别,有些资料:
HICC(High Instantaneous Current Capability),则可使扩音机的瞬间电流供应与控制能力大大提高,对於突然变化的声音信号,亦可作出灵敏的反应,以确保供给驱动扬声器的电流信号有良好的控制,而对於高低突发变化的声音,亦可减少电平过高或不足的误差。
提高瞬间电流供给能力
带有强力磁路的现代扬声器需要更高的瞬间电流供给能力。即使是具有相同功率规格的放大器,也会因这一能力的差异而导致各不相同的驱动能力.通过对电源部分/电源模块部分进行彻底的低阻抗化,大电流部分采用OFC超粗配线材料,采用LAPT功率晶体管,使信号通路最短等内部布局改进措施,大幅度提高了对实际扬声器驱动力有很大影响的瞬间电流供给能力。
我想这解释了为何玉米版说的在大动态交响乐上,哈曼优点更明显的原因吧
刚看了哈曼网站,看来应该北美市场买家很看重HCC的参数,不然厂家也不会把这个标上面,退一步至少说哈曼很看重这项参数对放大机的意义,也算是哈曼的一个设计理念吧

还有如果最大有80A 的电流,那需要多粗的专用电源线?80A 是不可能的事!
这个说法有误,在有电容器,加热器和马达的电子电路中,在电流接通的瞬间,必将产生一个很大的电流,这种浪涌电流作用的时间虽短,但其峰值却很大。在转换电源,开关电源,UPS电源中,这种浪涌电流甚至超过工作电流的100倍以上。
某些电器里出于提高HICC设计的80A高电流,应该还不算什么,时间只要够短就行了,机器是可以承受的,关键是通过大电流的部件本身够皮实。
当然,皮实就又涉及到用料成本了。。。。

这个说法有误,在有电容器,加热器和马达的电子电路中,在电流接通的瞬间,必将产生一个很大的电流,这种浪涌电流作用的时间虽短,但其峰值却很大。在转换电源,开关电源,UPS电源中,这种浪涌电流甚至超过 ...
一个简单的方法,首先我们不讨论那么深奥技术(因为一般的发烧友看不懂,也听不懂),普通家庭电源分支线2.5mm铜线,空调是另拉主线,空调在启动时电灯会明显的眨一下眼,那台80A 的功放启动时岂不会更厉害?我想不会的。如果真要测试,可以用大功率的8欧负载电阻测试,不必用音箱去冒险!
