有冇ching試過? 粒dac好似好雞

TOP

SDAC 用料其實都唔係話雞, 反而係為左USB Audio Class 1而刻意做成只能解最高24/96呢下先奇怪...

TOP

呢部野都出左一段時間.
比單買DAC+單買AMP平.
又不是長期開買.
有時會快閃開買一天,一星期...不等.
之前間中有CHING錯過左.

Audio format : up to 24Bit/ 96kHz <-- 解碼後,不是decodec
睇左AK4452 4個FILTER frequency response 會易明D.

嗰條線我已有.
O2 + SDAC 係嗰 GRACE SDAC + OPAMP 組合中最平.
GRACE SDAC 仲有其他 + OPAMP 組合,只是$$$$$$$$
配膽嘅都好幾款;



O2 + SDAC 150 美元; LCX + SDAC 380 美元 ( GRACE SDAC + Liquid Carbon X)
CTH + SDAC 305 美元
咸魚青菜,各有喜好.

有無需要入返過ADAPTER?

講起咸魚青菜, CHING有無玩過JDS部ATOM Amp, 外國評價係取代o2 amp的新平民救星呢~

TOP

無,實在太多選擇.
接觸面,時間,金錢有限.
一年中有兩三件嘢玩已經好開心.

TOP

的確選擇太多,今年我都只係TOMLEE倉到買左隻$299 K141MK2就無買過野

TOP

O2最抵玩係可以換opamp, 最後玩到49990ma x4 + SS3602 封頂就退燒
