For me, one big downside is that the DAC does not take USB input. The USB slot is only for thumb drive or similar. Can’t connect to your file player using USB. So limited to only DSD resolution if you use AES/EBU. I drive a pair of Wilson Sasha with it. Volume usually at 54 to 66 when connecting to aurender N10
Boulder's digital input lacks RCA/BNC for S/PDIF, but interestingly, it features an XLR connector for AES3. This appears to be a manufacturer's insistence. However, connecting USB devices is simple; you can easily do so by purchasing an additional USB digital-to-digital converter (DDC), such as the Weiss INT204 or dCS Network Bridge.
@@feverSoundHK Thanks for the suggestion, I will look into it. I'm using AES at the moment, already pretty happy with the results. Just hope to squeeze more out of it 😊. But that would still limit it to the resolution supported by AES?
Some manufacturers with a more "professional" orientation might believe that bitrates above 192kHz don't bring substantial benefits. Some even argue that high specifications are primarily marketing and promotional tactics. Additionally, they may consider USB interfaces as not inherently "professional" due to latency issues. While I can't speak specifically for Boulder, this perspective is held by some manufacturers in the industry.
@@feverSoundHK What you said make alot of sense. Boulder started off from professional audio. Hence all their equipment only has balanced inputs/outputs. The Boulder DAC that came with the 866 sounds amazing to me. Just hoping to have more options to play or experiment with, to be able to make those A/B comparisons.
Great review. I bought the 866 recently. Very musical all in one with outstanding bass. The built in dac is very close to my external dac (DCS Bartok 2.0), so it’s a bargain and I think that new buyers should go for it. An issue I face with the 866 is that it makes a static pop sound when lower the volume eg muting or lowering from 70 to 32. And again when I raise the volume up. Not sure if you have similar experience.
During my demo, I didn't encounter this issue. However, it does require the volume to be turned up quite high for it to function normally, and this has been somewhat troublesome for me. If I were to use it, I would definitely set it to operate in "pure power amp" mode (AV Bypass), pairing it with a high-quality streamer DAC-preamp. This should provide stability and excellent sound quality.
@@feverSoundHK you could be right, I haven’t tested it in pure power amp mode. But that’s going towards multi-boxes, away from all in one, which doesn’t get better than this (866). I also have the Lyngdorf TDAI 3400, but it is less impressive in all aspects except for room correction. But 866 just sounds better even without room correction.
@@hkgoodman888 different countries, so not meaningful to compare. I have checked HK price, was quoted around 100,000. That’s very attractive compared to my country.
This is a good question because I've owned the Diablo 300 for quite some time and am familiar with its sound. In short, in terms of power, there's not much difference between the two. Looking at the specifications, the Diablo 300 has slightly higher numbers, but in practical use, I find the 866 easier to match and achieve good results. The Diablo 300 can sometimes exhibit over-damping with certain speakers, requiring more careful consideration in speaker pairing. Personally, I'm more excited about Gryphon's upcoming integrated amplifier, the Diablo 333, but that is a more expensive option.
一出就買,推Magico , Wilson 喇叭完全冇問題,(非旗艦系列)力水,音質,定位都十分滿意.
我有機會都想試下推座地係點，因為我見唔少人用佢就係推座地喇叭（國仁）
@@feverSoundHK th-cam.com/users/shortseSHn_wKctgs TH-cam 打 Boulder 866 幾癲都有🤣 坦白講 十皮冇可能彈.
Jay 是 Ultra High End 發燒友，也是 Boulder 的愛好者，佢愛到親自去 Boulder 廠房參觀報道，以及和 Jeff Nelson 做了一個很好的訪問，很值得去看看（國仁）
@@feverSoundHK 👍我一向有follow佢
好吸引 , Thanks 國仁, Thanks feverSound
Thanks! 國仁兄講嘅不足，都接受到！wish list 先😂😂❤❤
謝謝 SoYee 兄的super thanks，感激～（國仁）
feverSound團隊加油～✌️😊
感謝恭兄，今日我哋夜咗出片～（國仁）
@@feverSoundHK唔夜～能夠見識到部咁正嘅串流擴音機非常好呀！😊
我自己意見,買得呢部都係有要求,我會選擇純Amp版本,始終digital會過時,另外原因少一樣野就少一樣野壞,少左Dac可能部Amp仲好聲Ｄ,買得呢部起碼買番部中上級串流.
同埋可以自己夾返鍾意嘅聲（國仁）
－部很好的amp, 解碼串流出奇的好，若分開買的話無三四萬以上都難贏佢。用佢推過很多喇叭牌子全部都有好效果，包括3/5a，估唔到哩😊 沒有重調味，但给你很從容大氣的感覺。聽Jazz特別正
很正的用家分享（國仁）
10皮野睇見真身已經好吸引，做工都好精細、聲音一定唔會有失望。感謝國仁詳細解釋的設定，感謝feverSound團隊！加油💪🏻💪🏻💪🏻💪🏻
其實而家廠家越出越多中高價 all in one，證明市場都有呢個需求（國仁）
係正嘅，不過感覺又有d微妙，用同價去拆開玩似乎唔易做到同等/超越嘅聲音，因為仲要計一堆線同配件，但all in one上到呢d價，發燒友又會屁股痕想拆開玩😂
無錯，所以係咪一件過其實係睇自己心態同玩法（國仁）
分開DAC 好啲， 少好多digital part 干擾
If I am knowledgeable enough I would rather get another DAC so I can try different combination. But as a newbie, I would rather go with all-in-one.
條片幫到手,好波🎉🎉🎉
幫到手就好（國仁）
喇叭冇bi-wire
我用緊866, 不是all in one, volume 開60-70已經好足夠了， 未試過開8,90
Boulder 当然永冇失手
擴音機一定不會失手，想不到連dac串流也似模似樣（國仁）
All in one 866 + 804 = WIN !!
推到，無問題（國仁）
如果好聲聽得你開心，十皮野根本唔貴，一部靚機閑閑地用最少10年或以上，每月唔駛一千元，而且二手放出又有人接，你去旅行去幾次已經用哂十皮野
呢幾句如果係我講就實俾人鬧硬😝但我私人係非常認同你👍🏻（國仁）
😂旅行講體驗，呢部野成本幾多唔使多講
發燒友來講, 分開玩會彈性較大, 若然Budget所限, 柯現溫又聽得下嘅, 做乜唔一部過呢?
寸金尺土之下慳地方, 又方便, 但始終都要試聽過至知是否合自己口味。
無錯，有時有啲朋友，想個廳簡潔啲，真係唔想太多機太多線，但又想靚聲，呢類產品就應運而生（國仁）
其實個人唔太喜歡咁大個顯示屏, 無論乜嘢技術, 顯示屏都係噪源. 所以如果有得揀, 最好就係將串流機同個屏擺開, 解碼,合併機就唔好有咁大個顯示屏😉
其實我都唔鍾意呢個大芒，事實上最好都係有芒熄芒（國仁）
feverSound團隊加油～
請推薦搭配866的電源線，感謝！
力水ok就得，但我會揀幼細少少嘅夾（國仁）
@@feverSoundHK 有訂購Shunyata Alpha V2 NR再來試試。
好正嘅All in one. Thanks 國仁分享
最緊要睇得開心（國仁）
All in one Hi End 機之中歐美最賣得係 Hegel，香港好少人講，係咪代理唔進取或因為 MIC？最新部 H600 可以同 Boulder 比試就好啦！價位同功能上差唔多，Hegel 都比較暖聲，推力亦唔少嘢，希望國仁測試一下😅
蝦餃都係好嘢嚟，小弟以前在HiFi Review兼職時也都試過，至於而家則有點難說，要等合作機會（國仁）
Boulder 好力堅正，聲靚 ❤❤❤❤。
確係靚～ 其實我試嘅唔止呢兩對喇叭，更加感受到（國仁）

終於緣份到 XD（國仁）

謝謝 hanghang（國仁）
2萬的DAC應該好聲過 build in 的 DAC。可以選 R2R的 或 ES9038的 DAC。
20k 的確都有唔少選擇，不過仲要諗埋串流部份～（國仁）
但ES chips通常比較硬底的聲音，用AD還不錯

👍💯🙏國仁加油
thanks 收到晒（國仁）
Thanks for sharing!
thanks man（國仁）
如blouder肯出部迷厘版外觀嘅3060合併amp就靚絕，另國仁兄話要開到80~90先夠声，係咪代表866唔可以推到座地？
唔係，而係佢將最常用的音量範圍設在70-90的範圍，感覺有點怪而已（國仁）
would it be too much for SCM7?
Yes, a little bit too much
Can you compare it with Soulution 330 and Orpheus I200 ?
unfortunately not yet
睇片頭已經勁吸引～
gogogo，去到片尾小弟都有嘢問下大家，你嘅睇法又點呢？（國仁）
Good
Yes another very nice review with English text
thanks to you for subscribing us
當然買埋啦！應該會夾啲。😅
fantastic review
thanks for your kind words
覺得分開好D，始終network 嘢仲係快速進步中，分開換會更好
分開就靈活性高啲（國仁）
正呀!會唔會試多D呢個價位既amp 呀!
會，市場原來都幾關注呢個價位的合併機，不過我哋都唔會遺忘入門產品嘅（國仁）
推805d4 可以嗎？
完全無問題（國仁）
👍🏻

thanks Will 兄回覆（國仁）
Nice review! But I think I’ll buy Accuphase E4/5000, it’s cheaper and better quality
They are just different sound characteristic, quality is absolutely the same grade
@@feverSoundHK Oh that’s good to hear! What’s the difference in sound going from the Boulder to an Accuphase?
呢部如果我揀會揀all in one. 好似外置都要花多好多先有聲音進步 只為介面的進步又好似唔係幾值得
的確係，因為好多 all in one 係偷輕咗某啲位，就價就成本，但呢部去到呢個價位，就做到好平均，而且最重要係佢嘅擴音機部份係完全唔使擔心，用家可以揀自已心愛嘅喇叭夾（國仁）
十幾萬做後級又有其他選擇啦！
但唔加串流解碼，又平返一截呢（國仁）
老虎都要埋解碼
仁哥，保重身體😊
有心有心，而家好返晒（國仁）
去到十皮真係有點矛盾，點正既機都會想升級 但佢5合一。你想搞都唔知點搞。
