Interesting comments in their FAQ

The DACs we're using—AD5791—were billed as "the industry's first true 20-bit DAC" by Analog Devices when it was introduced in 2010. Note the words "first" and "true." This is not 20-bit as defined for audio applications, this is not 24-bit delta-sigma, this is not (nudge, snicker) "32 bit" complete fantasy stuff. These DACs have never been used in an audio product until now. Normally, they are used for medical device imaging and weapons targeting—applications in which accuracy is absolutely paramount. Now, we're using 4 of them in this product—2 each per channel, for true differential hardware balanced design. Beyond that, an uber-simple discrete JFET buffer stage and discrete JFET summers (for the single-ended output) complete the picture.
Because they require very, very special care and feeding. AD5791s aren't "bolt in and go" DACs, with pleasant little paint-by-numbers application notes for use with audio. They don't even accept normal digital audio formats. Managing their use with multiple input bit depths and sample rates is, well, challenging. And special care has to be taken with their output. Plus, people are more focused on silly claims like "32-bit" DACs and "Giga-Rate" DSD. "21 real bits," doesn't sound real sexy in that context.

Direct purchase from Schiit, 15 days $ back guarantee. 15 days too short for break-in.
Can't wait to A/B with full stack Auralic Aeries+Vega in a couple of weeks.
Seems a promising DAC

唔掂啦部機
有人試過AB比較，連Accuphase DP 410都抽低佢，新出一陣就有人$15,000放二手，美國買仲有得拎返屋企試，原價退，都要放二手。即係煲完煲熟部機都係咁。
不如買Metrum，Metrume Musette同Pavane性價比都一流。

Unfortunately Metrum is not popular in the US, I need to pay more attention and look for one. Thanks for the tip. Have not done the A/B against Auralic yet, still cooking ....

個名點讀

Metrum Octave 只係 group 係 Good Stuff 內, 同 Class E+ 有一段距離。
Class E+ ＞ Class E ＞ Very Good Stuff ＞ Good Stuff ＞ Recommend for Others
當然網上野，只可當少少參考, 不可全信.

以前借過十多部DAC返嚟玩，有平有貴，最鍾意都係Metrum Octave同埋部痾到碌分身家機，兩部都係1 bit機，部Octave好特別，連Op Amp都無用，幾粒神秘ic並聯就直出RCA插，反而佢啲大佬用埋啲lundahl牛，都有啲驚會衰聲咗。

部Schiit就第一回合走人，同以前Theta啲機差不多，硬橋硬馬

大家的DAC 是否長著，使一開機便好聲

#18 - Ahleung :

煲咗一個月唔夠，D聲好正呀。報告完畢。

#20 - joeyd :

保完息機隔幾日再開會差好遠嗎? Thanks

#22 - marclee37 :

我架YGGDRASIL 返左黎3日, 有生以來, 幾廿年聽過的原來都係唔真既聲. 宜家D聲好真實好豐富
聽返足每個數字

多唔多人用呢架? 太精采.

第一段文個介紹, 全沒提佢既強處. 係R2R完準計算 VS DELTA SIGMA估計式演繹.

我用Saga, 我怕了要用2套 matched 6SN7。
加左Saga, 全面好過 Yggd 直入胆後。
我用RCA 6SN7的。

#26 - emanhkg :

我原本也是全balance的。
等到出SSVT後再轉Freya。
4支 matched 6SN7差不多要2/3机價。
早買早享受

DAC PCM1704u
不用較yggorasil 好

#30 - Faigoal :

請問呢部好機幾錢，一定要網購？
