※ 引述《Tosca (hi)》之銘言： : 簡單介紹一下這台DAC為什麼引起這麼多討論 : 說穿了就是幾個賣點 : 1.ladder DAC : 2.non-oversampling : 3.no digital filter : 4.most important--> no one know which chips he used!! Metrum Octave的團購取消了，小弟又對國外購物苦手，尤其手上的MOTU 1224音效介面又壞了，落入無音樂聽的狀態，對DAC的需求實在有點急，不太想再等東西慢慢的從歐洲過來。想再請教一次各位大大，有沒有哪位用過台灣之光MHDT？查過資料發現這原本是一個台灣公務員DIY的牌子，後來越做越大熱銷海外，有了規模以後連電容都用訂製的製品。他做的DAC以Havana最紅， http://dhost.info/mhdtlab/havana.htm Tosca大講的Octave前三賣點它都有，除了第四點晶片用的是骨董PCM56P以外。另外現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部分的設計倒是沒啥差別。價格方面Stockholm是1028美金， Havana是854美金，跟取得Octave的成本也差不多。價錢便宜固然重要，但是最重要的是聲音，在Head fi上面有一串超長的討論串在討論Havana改機後的表現，據說是脫胎換骨判若兩機，改完就跟吃了大補丸一樣驚人。 http://www.head-fi.org/t/310441/mhdt-havana-dac 我看了AudioGon上面一個網友Eugene81的評論，他把Havana跟一堆機器PK過，對比的結果有點生火，害我現在很想直接衝下去。 http://forum.audiogon.com/cgi-bin/fr.pl?ddgtl&1350296042 下面節錄他的文章並簡單翻個大意：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 這篇的大意是他現在的主力機種是Havana，但是原裝版本的聲音雖然有著獨特的聲音質感，但是缺少了解析、動態、延伸以及權威感，曾經被他打入第二系統。但是在他幾乎把所有原件都換了以後， Havana已經是他手邊最好的DAC，甚至還把Berkeley給比下去了！ (OMG...這也太突破天際了吧！) Havana改完以後保留了原來的聲音特色，但是把所有缺點都給補完了，原本的長處則變得更強， Havana的線路相當敏感，改動元件會在聲音上很直接的反應出來。下面則簡單形容了Havana、Calyx、Octave等三台DAC的聲音個性。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. 第一段大意是說Stockholm只是在接收訊號上做了更新，跟Havana比起來他不會特別心動，因為會影響聲音的DA部分幾乎是一樣的。第二段大意是他沒辦法描述Havana改了跟沒改差多少，因為差太多了，差了好幾個級距！原本Havana並不能算是偏解析或動態強勁的DAC，但是改完以後的Havana是他用過解析度最高甚至動態最強的DAC。只是改機的費用頗高，甚至會超過原本機器的價錢，但是特別的是Havana改機以後就能輕鬆上打，面對貴很多的對手也是臉不紅氣不喘。 (苦主看樣子是Berkeley) 第三段是Calyx的聲音特色，不想買韓貨，不翻了。第四段描述Octave的聲音， Octave在他的系統裡面很稱職的取代了Berkeley Alpha，並且完全沒有降級的感覺，最大的特色是聲音的分離度跟純淨度，相當乾淨的自然聲音而且有著良好的動態跟樂器殘響。以Octave的價錢來說，CP真的相當高。但是在他的系統中，Octave的音像扁平，並且高音跟Berkeley比起來略顯尖刺(但價錢差很多)。他其實可以接受Octave的聲音，但是當他改過Havana並且聽過以後，他就知道他回不去了(戰)！ xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx分隔線xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx 總之Havana看樣子是相當有搞頭的機器，新的Stockholm可以完全支援192khz更讓人覺得放心。而且平衡板本MHDT也有提供(而且沒有貴很多)，只是這麼漏漏長的重點就在於.....要改機，改機就能上打Berkeley Alpha！(戰) 只是...我對改機技術相當沒有自信，應該可以買好機器跟備好零件以後找師父改？或者...請女友上汪踢板徵工具人改是一招!?(大誤) 還是根本就不應該買Havana? Teac UD-501最近也超生火的，勝旗定價29900比日本還便宜又能播DSD，國外看了三篇文章，第一篇說Mytek大概是Meitner MA-1的90%，第二篇說Mytek跟UD-501比起來在空間感、解析等都好上一些。第三篇說Meitner比UD-501好不少，但是UD-501雖敗猶榮。基本上就是很符合身價的表現。 myav還有人這樣評論： "將G-03X訊號關閉並解除P-05與D-05的同步模式再度比較, 發現D-05與UD-501兩者的差異的確是變小了,雖然D-05還是略勝一籌但以聲音的流暢度來說,兩者已經十分的相近. 以近十倍的價差UD-501的表現已算是可圈可點,C/P值簡直高得破表..." 好像買UD-501也是一個很好的選擇... 結果，我究竟該買哪台@@ -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 118.232.176.251
