※ 引述《Tosca (hi)》之铭言： : 简单介绍一下这台DAC为什麽引起这麽多讨论 : 说穿了就是几个卖点 : 1.ladder DAC : 2.non-oversampling : 3.no digital filter : 4.most important--> no one know which chips he used!! Metrum Octave的团购取消了， 小弟又对国外购物苦手， 尤其手上的MOTU 1224音效介面又坏了， 落入无音乐听的状态， 对DAC的需求实在有点急， 不太想再等东西慢慢的从欧洲过来。 想再请教一次各位大大， 有没有哪位用过台湾之光MHDT？ 查过资料发现这原本是一个台湾公务员DIY的牌子， 後来越做越大热销海外， 有了规模以後连电容都用订制的制品。 他做的DAC以Havana最红， http://dhost.info/mhdtlab/havana.htm Tosca大讲的Octave前三卖点它都有， 除了第四点晶片用的是骨董PCM56P以外。 另外现在也推出了可以接受192khz跟支援非同步USB的版本Stockholm， http://dhost.info/mhdtlab/stockholm2.htm DA部分的设计倒是没啥差别。 价格方面Stockholm是1028美金， Havana是854美金， 跟取得Octave的成本也差不多。 价钱便宜固然重要， 但是最重要的是声音， 在Head fi上面有一串超长的讨论串在讨论Havana改机後的表现， 据说是脱胎换骨判若两机，改完就跟吃了大补丸一样惊人。 http://www.head-fi.org/t/310441/mhdt-havana-dac 我看了AudioGon上面一个网友Eugene81的评论， 他把Havana跟一堆机器PK过， 对比的结果有点生火， 害我现在很想直接冲下去。 http://forum.audiogon.com/cgi-bin/fr.pl?ddgtl&1350296042 下面节录他的文章并简单翻个大意： 第一篇： 10-17-12: Eugene81 I've owned all 3. First the Havana, then the Calyx, then the Octave. Now I am using the Havana in a highly modified form -- pretty much all caps replaced, several with V-Cap CuTF, DAC chips, power transformer, diodes, key resistors, WBT silver RCA outputs, BNC input (all parts replacement, no alterations to the board). There is a huge MHDT Havana thread on Head-Fi that goes over all of these mods. I never sold the Havana but bumped it down to a second system; it has special qualities of timbre, texture, and PRaT that are unique IMO, but lacks a fair amount of detail, dynamics, extension, and authority in its stock form. Now it is back in the main rig and is easily the best DAC I've owned, which includes both Berkeley DACs. The heart and soul of the original is retained, but the shortcomings are all rectified and the strengths are improved upon greatly as well. It is also nice that you can tune the sound by replacing certain caps and of course the tube. The Havana is quite responsive to changes. To answer your questions, based on memory... Warmest: Havana Smoothest: Calyx Organic: Havana Lightest: Octave Clearest: Octave 这篇的大意是他现在的主力机种是Havana， 但是原装版本的声音虽然有着独特的声音质感， 但是缺少了解析、动态、延伸以及权威感， 曾经被他打入第二系统。 但是在他几乎把所有原件都换了以後， Havana已经是他手边最好的DAC， 甚至还把Berkeley给比下去了！ (OMG...这也太突破天际了吧！) Havana改完以後保留了原来的声音特色， 但是把所有缺点都给补完了， 原本的长处则变得更强， Havana的线路相当敏感， 改动元件会在声音上很直接的反应出来。 下面则简单形容了Havana、Calyx、Octave等三台DAC的声音个性。 第二篇： 10-18-12: Eugene81 I haven't listened to the Stockholm, but I am not really enticed by it as it is largely the same as the Havana except that it accepts 192 KHz max input frequency vs 96 KHz with the Havana and also has asynchronous USB input and an added BNC input. There is at least one account by a Stockholm user that both DACs also sound nearly identical with standard resolution recordings. Async USB seems to be best handled by an external converter, the RCA SPDIF on the Havana can be easily replaced by BNC, and I'm not gung ho about 24/192 recordings as they are sparsely available and expensive. I am actually looking for a second Havana and if I run across a used Stockholm at a competitive price I might consider it. I cannot understate how much the Havana can improve over its stock incarnation -- I mean many leagues better. Havana owners can probably all agree that it is not a highly detailed or dynamic DAC, but it is clearly the most detailed DAC I've had in my system now and maybe the most dynamic as well. It is really something special when you put very good parts in it. The costs add up (especially the teflon V-Caps!) and well exceed the price of DAC itself, but in the end it can easily stand up to, and I would imagine for many people beat, far more expensive units. I enjoyed the Calyx a lot. It has a BIG presentation, quiet, quite detailed, great dynamics, with good weight and body, but a little too soft around the edges to be well rounded if you have eclectic tastes in music. The major detractor for me was that vocals have a diffuse quality about them as if your wall is singing and not focused like there is a person in the room. Still a pleasant and musical DAC. The Octave didn't last very long in my system. It succeeded the Berkeley Alpha DAC Series 2 (a wonderful DAC) so it had big shoes to fill and it did a very respectable job. The most notable attributes were the clarity and separation. Very clean sounding and very good, natural tone. Good dynamics, particularly extended decay. I can see why this DAC gets such positive press, especially considering the price. However it is not without fault and for me the issues were that I found it somewhat flat sounding in terms of imaging and the highs could sound a little brittle compared to the BADA 2 (remember, 5-6 fold price difference). I think I could have lived with it if I had to, but I would also be fully conscious of its weaknesses, which is why it's always hard to take steps back. But then I tried the CuTF output caps in my Havana and immediately knew I had to go in that direction. 第一段大意是说Stockholm只是在接收讯号上做了更新， 跟Havana比起来他不会特别心动， 因为会影响声音的DA部分几乎是一样的。 第二段大意是他没办法描述Havana改了跟没改差多少， 因为差太多了，差了好几个级距！ 原本Havana并不能算是偏解析或动态强劲的DAC， 但是改完以後的Havana是他用过解析度最高甚至动态最强的DAC。 只是改机的费用颇高， 甚至会超过原本机器的价钱， 但是特别的是Havana改机以後就能轻松上打， 面对贵很多的对手也是脸不红气不喘。 (苦主看样子是Berkeley) 第三段是Calyx的声音特色，不想买韩货，不翻了。 第四段描述Octave的声音， Octave在他的系统里面很称职的取代了Berkeley Alpha， 并且完全没有降级的感觉， 最大的特色是声音的分离度跟纯净度， 相当乾净的自然声音而且有着良好的动态跟乐器残响。 以Octave的价钱来说，CP真的相当高。 但是在他的系统中，Octave的音像扁平， 并且高音跟Berkeley比起来略显尖刺(但价钱差很多)。 他其实可以接受Octave的声音， 但是当他改过Havana并且听过以後， 他就知道他回不去了(战)！ xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx分隔线xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx 总之Havana看样子是相当有搞头的机器， 新的Stockholm可以完全支援192khz更让人觉得放心。 而且平衡板本MHDT也有提供(而且没有贵很多)， 只是这麽漏漏长的重点就在於.....要改机， 改机就能上打Berkeley Alpha！(战) 只是...我对改机技术相当没有自信， 应该可以买好机器跟备好零件以後找师父改？ 或者...请女友上汪踢板徵工具人改是一招!?(大误) 还是根本就不应该买Havana? Teac UD-501最近也超生火的， 胜旗定价29900比日本还便宜又能播DSD， 国外看了三篇文章， 第一篇说Mytek大概是Meitner MA-1的90%， 第二篇说Mytek跟UD-501比起来在空间感、解析等都好上一些。 第三篇说Meitner比UD-501好不少，但是UD-501虽败犹荣。 基本上就是很符合身价的表现。 myav还有人这样评论： "将G-03X讯号关闭并解除P-05与D-05的同步模式再度比较, 发现D-05与UD-501两者的差异的确是变小了,虽然D-05还是略胜一筹 但以声音的流畅度来说,两者已经十分的相近. 以近十倍的价差UD-501的表现已算是可圈可点,C/P值简直高得破表..." 好像买UD-501也是一个很好的选择... 结果，我究竟该买哪台@@ --
