DirectStream DAC 直出後級 vs Devialet
本帖最後由 n-tone 於 2015-12-30 21:08 編輯話說之前減價終於入手部 PerfectWave Transport 加上個得到多項奬嘅 DirectStream DAC， 真係唔簡單：所有 CD 真係唔同哂 — 聽到以前聽唔到嘅細緻、動態！
而我暫時只係用返 Cambridge 個 AV amp 推，都巳經有好明顯嘅分別！
我諗住我幫個 DAC 搵個後級想直接連上，因為 PS Audio 話 there's no pre-amp like no pre-amp。話雖如此，PSA老闆 Paul McGowan 自己都有用前級，而 PSA 自己都將會出部前級，不過我覺得 DAC 直出 power amp 最冇失真，亦唔會加鹽加醋...感覺會最「真」，最有母帶原意。大家又點睇？
當上網睇下後級報告，例如 HEGEL H300 同 Jeff Rowland 525，同時亦見到 Devialet 120 / 200 , 而不同雜誌同網媒都對 Devialet 有非常之咁好迴響！...{:1_257:} 我甚至見到有啲 DirectStream 用家轉會，話 Devialet 內置 DAC 同 PSA 有過之而無不及！可能加上 S.A.M.嘅喇叭對應？ 我估要搵日上方浪...
各位 Ching 有咩建議呢？ 無前級，增益唔夠，動態不夠像腳軟，像MC頭沒有風佬一樣 hksarac 發表於 2015-12-30 22:26 static/image/common/back.gif

那裡有試用&入手幾$? 睇 DirectStream 個 Spec，見個 Output Gain 都唔細，似乎可以直驅後級，小弟覺得用後級會穩陣啲，PS Audio 會有新後級出，可以諗諗。 本帖最後由 kakui 於 2016-1-1 05:13 編輯
我現役兩部老爺dac delius 、msb p dac ii.
都係直出後級，感覺良好。
Devialet 梗係好啦，
已經打算賣機 上！ 小弟用Teac UD503直去Crown Itech 5000，有Eso聲底，加上
可以調5同聲，大滿足。 jackt 發表於 2015-12-31 11:48 static/image/common/back.gif

感謝各位回覆 + 新年快樂！{:1_352:}
PS Audio 後級你係指 BHK 250 / 300?

不過咁巨大，唔使錢老細都唔批.... ~_~
所以 Devialet 一體化而音質能夠直迫 PS Audio DAC + preamp / amp嘅話就好吸引。
Paul 話直出後級 vs 經過前級都好 depends 你套 setup. 正正因為咁, Devialet 嘅 SAM 可以發揮喇叭 maximum potential?....而且
PS Audio 將會推出嘅前級，資料 from Avshowroom forum:
" The preamplifier is a full function line stage, featuring five single ended and balanced inputs, a discrete Class-A MOSFET headphone amplifier, all classic through-hole construction, PRP resistors, assignable home theater bypass, and a fully balanced design. Based on a pair of zero feedback 12AU7 current sourced vacuum tubes feeding a class A MOSFET output stage, the BHK Preamplifier enjoys extreme linearity with a rich and open sound.
Unique to the preamp's design is its multi-stage stepped attenuator. High voltage analog switches and gold contact relays are incorporated in a two-stage process of linear attenuation. The first stage uses a classic, single element, variable shunt attenuator feeding the vacuum tube input. Finer adjustments are made through varying the actual gain of the vacuum tube and together, form a sonically-invisible attenuator. Release of the BHK Preamplifier is scheduled for Q2/16 (MSRP TBD)."

平衡都只是5.3V rms，好多機都有 hksarac 發表於 2016-1-1 13:18 static/image/common/back.gif

睇返 DirectStrem DAC 個 spec，高輸出都有成 8dB，而一般前級都係得 10dB gain，所以部 DAC 直驅後級應該問題唔大。

Thanks Ching for digging the spec!
係時候要去試一試喇 :)
