前些年资本市场全部转向虚拟及移动互联网应用等市场,消费者电子设备制造业哀鸿遍野,众多品牌纷纷倒下,比如麦景图卖身数次,B&W,林道夫等卖给以前瞧不起的下游企业,暗自饮泣。更别提安桥,森海塞尔,过几年品牌能否保住都在未定之天。不过最近瞄了几眼不看好的AV设备企业,发现好像并没有那么悲观。虽然不清楚他们的财务状况,但至少表面看产品序列新品出的很快,型号也多,新的技术标准也在不断的进入到量产型号,用户的讨论也比较激烈,竟然依稀有了十年前蓝光兴起的那种一片繁荣的感觉,当然,是回光返照还是重新崛起不好判断。不过起码有了重新归纳一下最新信息和进展的价值,尤其是国内信息极端的稀缺和不系统。我这里大致归纳一下现有信息。

https://www.hdav.com.cn/play-hometheater/4897.html

  信息主要来自于国外论坛,主要讨论但不限于5000美金以下前级,16声道模拟输出(全景声年代这个因素极端影响成本及购买决策,蓝光时代这个因素没那么重要),基本上覆盖了国外主流产品,不乏当红炸子鸡。 微信号:860275582

  未知部分以“?”标识 微信号:860275582

  主流设备价格及SPEC(全部都支持Dolby Atmos, DTS-X, Dolby TrueHD, DTS-HD MA, DTS-HD, DD+, DD, PCM, ARC, Dolby Vision, HDR10, HDMI 2.0b+ HDCP2.2, RGB 4:4:4) 微信号:860275582

  均为美金含税价,ROOM CORRECTION代表EQ校正软件,国内比较少关注但国外比较重视的包括DTS-X-PRO,AURA 3D,IMAX,HDR10+等,不一一科普了,请自行查询。

  IOTAVX​这个品牌好像在英国第一次推出,比较新,其他的像ToneWinner​是国内天逸品牌,AT-300就是国内的7300型号变种,STORM等品牌国内也比较了解,就不一一说明。

  上面的总表比较全,下面进入到一些细节,型号不多,但多加了一些DSP或者DAC芯片信息,都是拉拉杂杂的帖子里归纳来的。另外自行理解一些变种机信息,二次开发不一定好与不好,厂家这种分工合作很多,比如创诺就曾经给百里登作硬件,AURA 3D也给创诺做过DSP板卡之类的。

  小注:比较核心的部分标红,比如几片DAC用于几个声道,高阶玩家可以关注,其他人无视即可。Streaming Support代表推流服务及协议,有些属于互联网项目国内并没有推出,比如Spotify, Tidal之类的。

  HDMI 2.1 Upgrade Promised表示厂家如何承诺解决HDMI2.1的BUG问题,我另一个帖子里也归纳过。

  为了版面简单点,输入输出接口等SPEC都删掉了,需要的请自行查询。

  比如下面这样的信息都去掉了:

  (备注:前三每个声道一片AK4490,其他声道每两个声道一片AK4490,这种架构成本很高,其他家没见这么搞的(根据后面坛友补充信息,Acurus Muse是十个声道十个1795,另6个声道3片1795共13片)。当然硬件具备,调试是另外一个重要环节。一般来说非初创企业,都会有一家合作很久,开发很熟悉的芯片企业来保证调试效果,某种意义上这就形成了普通消费者常说的声音风格。比如天逸常年和ADI合作。而MONOPRICE这种新企业就会把这部分研发外包,即使EMOTIVA这种老企业也有外包,据说和MONOPRICE共用了一个研发外包团队)

  有意思的是:哈曼卡顿集团用雅俊AV40一个架构做出来这么多机器,更有意思的是LEXICON哪去了?难道彻底被抛弃,用Audiocontrol品牌取代了?不知道有谁能解答一下。

  最后补充一下:由于日本AKM公司的大火,天龙旗下除了马兰士8805和天龙8500(合并机),其他所有型号据说都要更换DAC,此消息两个月以前爆出,现在进展如何不清楚,有意比如天龙6700这种型号的,建议多查询和比较一下,DAC更换等同于汽车换了发动机。

  6月20日补充最新信息,天龙更换DAC成真,涉及大量低端型号:

  NOTICE CONCERNING D/A CONVERTER CHANGES FOR SOME PRODUCTS

  4 02, 2021

  Due to the fire at Asahi Kasei Electronics Co., Ltd.'s semiconductor manufacturing plant on October 20, 2020, it has become difficult to continuously procure semiconductor components, including D/A converters, which are used in some of our products. We have continued to produce products using parts inventory already held by our company and parts newly procured from the market, but since it is expected that it will be difficult to resume supply of such parts at an early time, we have changed to replacement parts and have agreed to continue production.

  Since D/A converters are components that have a particularly significant impact on the sound quality of products, we selected alternative components, redesigned peripheral circuits and software, evaluated sound quality by sound master, and performed sound tuning in the same process as when the new product was developed. As a result, it is now possible to continue delivering products of the same quality as before the D/A converter change while maintaining the same sound quality, performance, and functionality as the previous products.

  We will continue to make every effort to deliver products that satisfy our customers, so thank you very much.

  Products subject to D/A converter changes

  AV Amplifiers: AVC-X6700H,AVR-X4700H,AVR-X2700H,AVR-X1600H

  更换的芯片应该是从AKM4458更换到了PCM 5102A。

  

2021-06-20 23_55_28-Denon Replaces AKM AK4458 DAC IC in X4700H and X6700H _ Audi.png

 

  2021年春天生产的机型就已经更换了,据说序列号右起第五个数字如果是7,表示用了新的 DAC,可能带来未知风险。

  但同时有另一则不知是否好消息:The PMA-A110 uses Burr-Brown (Texas Instruments).110年纪念款合并双声道功放。作者:jesson1971。
