Hello all,
It is 3:42am in Taiwan and I just got here from Japan.
Thank you so much Racewong and Hiendy.com for reporting Weiss products and everyone who provided valuable comments. Maybe I try to give some comments.
> Medus這全新model和Medea+的主要分別只是 加display screen、better software 及加強和改善了屏閉的psu，則似乎是有點兒不夠進取了
Retail price of Medus is the same as Medea+.
If one have ever owned a Medea+, one will understand adding the cost for optional items such as DSD option, front panel, remote control are more expansive than what current Medus costs. From business point, this means we provide something better at the same price. This also give us room to lower Medea+ pricing.
From technical point Medus allows its OP1-BP to run as preamp, that shorten the signal path and provide better transparency. I like using Medus at home driving a pair of active loudspeakers. To me this sounds so much better and ideal. 
> Medus 仍然只用一粒ESS9018，但其他brands 已開始在top models用 多粒9018行parallel mode 以改善音效。
I hope to maintain this conversation in technical perspective. Maybe one day Weiss will come up with a DAC with more than one 9018, but that will not means it is better than 1pc inside Medus. I thought this is a comment knowledge that a china made cheap DAC is using the same DAC chipset as Soulution but they are "different", right?
There are china made double ESS9018, and I guess some of its owners do think it is better than "ALL" DACs using just "one piece of ESS9018"?
> ESS9018其實是可以達到32/384的，但為甚麽 Medus 仍只是24/192呢？
Original Medea (made in 1999) is potentially capable to support up to 384kHz with Quad AES.
Medus (made in 2013) does not support 32/384 is because Weiss is an engineering company, but not a "marketing" company. I will try to illustrating more later on if possible.
> 須知近期 high resolution PCM 已是個大趨勢。 是否Weiss認為ESS9018 play 24/192 是最好聲，所以放棄更高的 resolution 呢？
Digital audio has been available for about 30 years. For practical and technical reasons we have quite good understanding it.
"近期 what is really 大趨勢" depends on what actually benefit the audio quality but not digital format. *I believe* Weiss can playback 768kHz as good as 192kHz, but there is no reason why one would want to do it. Every two years the digital format changes to something new, I don't know who would like to replacing their $160K DAC every 24 months. From last 13 years of Weiss consumer and 30 years of professional audio history, I think it is very clear that Weiss provides upgrade path when the time is suitable or needed for such upgrade.
It is funny as you can *ALSO* view my comments as Weiss doesn't do it because it can't.
It is free of choice to one believe.
> 假如 Medus只能支持到24/192，玩 DoP DSD file playback 的時候，能否 support DSD128 呢？
Medus currently can support DSD64, it cannot support DSD128.
MAN301 can playback DSD128. We have custom buying Jason as CD transport, MAN301+Integrita for file playback, Medus as DAC. This 4 boxes combo support almost all formats for now and future.
> 希望 Weiss 的 Asia partner - AsiaWeiss 能給 hiendy brothers 及小弟解答一吓好嗎？ 謝謝！
Thank you so much for providing a chance for us to comment. 
> 要成熟要隠定，都唔駛三代的 旗艦dac 都同是 24/192。
If I understand this comment correctly, 旗艦dac means "superior" and "superior" means playback above 192kHz is needed to benefit on audio playback. I'm not Daniel, but this is not Weiss philosophy. And this is not true to my understanding too.
> 好多HIEND廠的旗艦機都比 Medus 進取呢：它們能夠support的 PCM/DSD resolution 都比 Medus高，論穩定好聲，也未必輸給 Weiss。
I'm sure other manufacturers have their own mindset and feature to target their own customers. I have very high respects on all brands in the market. But pretending DSD128 is better than 24/96 is the same situation that one think recording DSD, then processing using analogue gears through extra stage AD/DA gives less "problem" than PCM. Supporting DSD256, DSD512, PCM384kHz, PCM768kHz as playback format is not what Weiss would like to do.
> 另一例子：Weiss 是有把它的 OP1-BP discrete opamp 供應給其他 hifi/CAS brands的。
> AudioNec 就是其一，它的SDV4 series 是 up to 384 的呢。
If I remember correctly, AudioNec does NOT using OP1-BP, but an INT202 interface. It has a DAC version which uses Weiss DAC2 as D to A conversion.
> Weiss 其實要戰勝自己，大步向前進步才對!
> Digital 科技進化神速，就如逆水行舟，不進則退！
I agree, for this I am very looking forward for MAN301 room acoustic correction and measurement software available. Improvements have been made on NEW INT204, DAC202DSD, MAN301, Medea+DSD and Medus.
> Daniel Weiss is one of the few who openly stated several years ago that 24/96 is good enough. I have his white paper on this proclamation.
Daniel actually thinks 16bit is enough for a playback format.
24bit is good for extra headroom in processing. 96kHz is more than enough definitely for human listening.
> Going to 24/192 is already slapping himself on the face and to 24/384 is a bigger slap.
i don't understand why makes such a strong statement that going 24/192 or even 24/384 is a slap in anyone face? humm..In professional audio field above 24bit/96kHz is not benefit on audio quality, but it maybe needed when ultra-high frequency information is valuable such as measurements and recording dolphin singing.
> Weiss products, old and new, are unable to play DSD 2.8 and 5.6 MHz and DXD 24/352.8 and 384 files.
INT204, DAC202DSD, Medea+DSD, and Medus are supporting DSD2.8.
MAN301 supports DSD2.8 and DSD5.6.
> Anyone who does not agree with what I said may ask and bring his gear to Ben Lau's place for direct comparison.
> I mention Ben Lau because Kent Poon does not even allow someone bringing his portable computer to his showroom (thus not even disturbing any of his setup)
We have many customers brought their computers to audition with our products. We also consult CAS settings, check up, custom installation for many of them. I don't understand this statement. I met Ben Lau during CES2009 (??). A nice gentleman, I wish him all the best and congratulate him continuous developing good audio journey. But I don't understand what brought him to Weiss audition environment or setting? Maybe I mis-understanding something here?
> I discontent only about Weiss not to incorporate 32/384 & DSD128 capabilities in the new Medea.
Weiss not to incorporate 32/384kHz on because there is no such playback format. AES/EBU or S/PDIF are digital transfer "standards". They are capable to transfer up to 24bit/192kHz. This means the max. signal of data transfer is -144dBFS. In professional post production environment, we always us 32bit floating point processing or double precision, this is very common. However when we finished our "post-production", signal is dithered or one would not care truncate to 24bit. For conversion purpose. Weiss does has products supporting 32/384 or even 64/384 and DSD128. This Weiss product has been in the market for at least 13 years and are using by George Massenburg, Bob Katz, 2L, USA SACD Center etc. Maybe 70% SACD you listen today is made by a Weiss during mastering stage.
Of course when one manufacturer states its DAC supports 64bit DAC as selling point, but the AES/EBU cut off anything below 24bit. This is up to audiophile decide if this particular 64bit DAC is benefit or not.
> The trouble in Hong Kong for a prospective buyer of audio gear is that he is unable to compare properly different products.
I agree, for that we provide home audition service. Maybe you do not know since we don't highly advertise on magazine or "bought" any reviewer?
Thanks again for the opportunity to comment and interest on our products.
If people want to have a flagship CD playback system, I have no idea why 768kHz or DSD512 are related. CD is 16bit/44.1kHz.
If people want to know if "Medus" is good or bad, or simply understand more deeply its function. The only way is to setup an audition. Good or bad sound has nothing to do with 768kHz or DSD512.
If people think Medus is not good simply because it does not support 768kHz or DSD512, I have no comment and simply respect his/her view.
I am sure we are listening to what customer wants. (e.g. using OP1-BP as direct preamp upto +27dBu (max. 17volt) analogue output)
I think one reason why Daniel and his team has been respected in the engineering and professional audio industry because he stands his feet on engineering ground, but not driven by wanting *JUST* to sell few more Medus.
Thank you again and if any question online of offline are welcome. I think everyone has my email, facebook or contact info. Tomorrow (today) we will run an listening event with Taiwan MyHiEnd, and I look forward to setup one in HK.
