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！
PerfectWave
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？
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:
PS Audio Preamplifier
" 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)."

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...
