DNA已经付预付款了。就等三月初发货了。

zana deux要二月底才开始接受下单，所以还得等，但出货时间大概是5月份。

现在考虑，zana deux是成熟产品，拥有极高的评价，zdt会否超越它呢？如果只是在功率上有所提高 ...

ZDT还是会超过ZD的，看它家的产品，倒是稳打稳扎。
而且在12AX7这种管子上，你还是能找到很多靓声好管的，比如德津风根的，速度/声场都算是典范之作，那种纯而静的声音，胆味迷人。ZDT改用这个管子本来就是一个提升。

DNA 用的 220v 牛, 好像還是比較小. 小心會因為牛而 delay. fcklo 大也說過.

到现在也找不到ZDT的听感，那边定的人还在等机器

At the risk of sounding like a moron, can someone describe how the ZDT compares to the regular ZD in regards to sound (for single ended). I know one is SET and one OTL, but as someone with little tube knowledge I'm not sure what to make of that. My understanding of SET amps is they work better with a wide variety of impedance headphones. For that reason I was considering the ZDT over the ZD (which I've heard and really like) 问zdt和zd哪个好，一个是otl线路 一个是set线路
回答：
I thought SET was Single Ended Triode, and that an amp is still a SET regardless of whether it has a transformer coupled output or OTL? I could be wrong. The ZD and ZDT don't sound hugely different, and I also thought the ZD still did well with 32 ohm Grados and 300 ohm Sennheiser. I have not been able to directly compare the two, but Blutarsky has both (unless the ZD finally sold) and he might be able to answer that better. With the ZDT I have not seen a need to have a high and low impedance switch like my WA6 or the WA22 prototype that I have here for next week's Colorado meet.
ZD与32欧的歌德耳机和300欧的森海耳机匹配非常不错，我并没有直接对比过这2台耳放，而Blutarshy有两个，最终他卖出了ZD留下了ZDT他能更好的回答这个问题

但不能不说的是，ZDT可以驱动耳机的范围还是要更多一些，如果能使用OUT TRANSFORMER的情况下，可以实现与ZD那种OTL相当的声音，这本身就已经是素质的体现了，三百美金 可以做到这些，还在可接收范围内。

ZDT推KK的效果还是有些疑虑，看HEAD-FI那边的听感。驱动KK还是需要在120欧输出阻抗的情况下，功率达到8W甚至更多，二房驱动的话，很难达到音乐传真A500A的那种动态犀利/低频下潜很好的爆棚效果了。

K1000
via 4-pin XLR: My K1000 (#1378 bess-heavy) sound fantastic off the Eddie Current ZDT - the best I have heard them sound to date. I was all ready to sell the K1000 if this amp didn't improve their sound to what I expected (and bring the K1000 closer to the level of my HD800), but it did it in spades.


The missing sparkle in the K1000 that I loved with Naamanf's B22 has now appeared, the vocals are more vivid and rich, macro and micro detail is noticeably improved, soundstage is more solid, and bass is as strong as before but now much better controlled. Plus they play as loud as I would like via the 4-pin XLR jack, when fed via RCA out of my PS Audio Digital Link III. So there is no advantage to using the stock K1000 speaker-terminal pigtail with them, and instead I can use ZDT speaker out for my Stax transformers (will try later this weekend). The PS Audio XLR out > Jensen transformers XLR-to-RCA converter > ZDT has slightly less volume at a given volume knob position, but the amp still has enough gain to drive them well.

None of my previous small 5-12 watt speaker amps can drive the K1000 as well as the ZDT (Travagans Red, Nuforce Icon, and Qinpu A-3), nor can my Single Power Square Wave XL balanced amp. The Sq Wave can play them loudly, but it cannot extract the same great sound from the K1000 like the ZDT, while Sq Wave XL is very nice with other normal headphones (like balanced HD600/800 or balanced/modded D2000).

My ZDT with a Sylvania gold pin 5751 and PS Audio Digital Link III DAC set for 192K up-sampling is fairly good with the K1000, and was better than all my previous attempts at amping them. But wiatrob's balanced EHHA was slightly better when I compared them side by side for 2 weeks last October. With GE black plate 5751 tube the K1000/ZDT was too dark. However, my SAC KH1000 amp is even better with my K1000 than both of those amps above.

HiFlight who sold me the SAC amp says the Red Wine Audio 30.2 amp is even better with K1000 than the SAC was. I've also heard the K1000 on Naamanf's Beta 22 amp, and my memory tells me that was also quite good as it was better than his O2 Mk1 on his Blue Hawaii amp. I just don't know how it would compare to the others.

Right now the K1000 are in my main rig with the ZDT, and the SAC amp is in my bedroom for the HE-5 and HD600, so that tells me the ZDT isn't so bad because I do use them with it. It's just not my first choice.
The ZDT is great with almost every headphone I have tried with it, but the K1000 have a special requirement, which is a speaker amp that drives 120 ohms well, or a headphone amp with gobs of power into 120 ohms. The ZDT is not bad with them, but it doesn't seem to bring out the K1000's best in terms of detail or bass. The EHHA and SAC（KH1000，也就是小刺猬） were brighter and crisper sounding with K1000, and bass impact improved with EHHA, and then got even better with SAC. HiFlight likes the RWA 30.2 amp with K1000 the most. So does mrarroyo.
这文中提到的 Red Wine Audio 30.2 amp资料见http://www.redwineaudio.com/products/signature_302#purchase，价值三千美金的功放。

多谢羊版翻译。
RPX300确实贵了点，不过它是唯一带前级功能的。。。

yangmetal

zana deux se也有前级功能，现在的zdt更加能直接推箱子

pig2man

哇，那不是很容易选了

davidxtb

MS并不容易吧，在这个价位上，要挑剔的东西实在是太多了

pig2man

唯一麻烦的是ZDT不容易买到吧？Rudi的渠道做得非常好，很容易买到。这其实是个很大的因素，我几次在js那里就很想直接买一个rudi好了，无他，就因为“它已经在那里”vs预定还需要等很久。

这种情况的机器,最适合买2手. 以前Single Power的耳放也是这样. 新机要付完钱等半年,2手已经在那里available.

pig2man

2手也要等嘛
有时候购买就是靠冲动，一想到很久才有就没兴趣了。我是很怕麻烦的，很多人不辞辛劳远赴重洋搬回来一套机器我真的吃不消，如果音质差不多又可以直接购买，贵点贵点呗~我觉得像我这么想的人应该不少吧

估计很难买到二手的，ZD有出二手的，但ZDT倒是没有见过。
至于素质吗，ZD出来有几年了，金身未破，评价一直很好。
至于ORDER之后，多久能拿到，半年能拿到都算是快的了，看HEAD-FI那边有几个家伙还在别人庆祝收到ZDT的帖子上留言说还在等

yangmetal

呵呵，确实，这样的手工小厂，都是攒了很多台才有的做……

估计rudi是先发货，后结帐，所以很多地方有的卖～～～
