採樣率可升頻至192kHzPS Audio Digital Link III DAC所採用的元件全是精挑細選, 數位訊號接收器採用Jitter特低的Crystal CS8416, 升頻晶片採用目前最好的TI SRC4192, 可以將所有不同採樣率的訊號都升頻至192kHz, 全平衡DAC解碼晶片也是採用目前頂級的PCM1798DB. 此機之輸出完全捨棄OP AMP, 而採用沒有回授的分離元件電路, 大幅減低SID，而訊號輸出放大也一樣捨棄OP AMP，採有溫暖聲音的FET分離元件A類放大電路. 而且從DAC晶片與 輸出之間都是直接交連, 所以低頻具有能量與衝擊力.
 
電源處理部份正是PS Audio的看家本領, 其採用一顆特別設計之超大變壓器, 使得此DAC有溫暖與耐聽的聲音，而且聲底乾淨透明沒有底躁, 聲音中性，是一台值得擁有的DAC。* j94 網路上對DAC之特色說明請參考,Digital Link III (DL III)所採用的元件全是精挑細選, 像採用Jitter特低的Crystal CS8416 數位訊號接收器, 將接受到的訊號流轉成平行流和分離出時鐘訊號. 然後經過目前最好的升頻晶片TI SRC4192, 將所有不同採樣率的訊號都提升至192kHz, 再以也是目前頂級的PCM1798DB全平衡DAC晶片進行解碼. 這個晶片擁有123dB超高的動態範圍, 0.005%的總諧波失真率. 不只如此, 它是採差動輸出, 以及8倍的超頻濾波.DAC晶片的輸出是電流訊號, 必須要轉成電壓訊號才能做處理. 所以DAC的輸出必須經I/V轉換電路, 這個I/V converter一般廠商就是用OP AMP簡單解決, 但OP AMP內部都帶有回授設計, 加上DAC輸出的訊號頻率高, 就容易產生一種稱為Slew Induced Distortion SID的失真. DL III完全捨棄OP, 而精心設計沒有回授的分離元件(電晶體)電路, 大幅減低SID .從I/V converter輸出的電壓訊號, 因為帶有高頻的高速交換噪音(switching noise), 必須經過低通濾波器(low pass filter)將不需要的過高頻訊號予以濾除. 一般廠商也是用OP AMP做主動式濾波, 可是這一樣碰到因為高速與回授合併造成的失真. DL III這裡寧可採用被動式的濾波法以避免失真.接下來的訊號就需要經過輸出級放大成約1至2伏特的 ( ), DL III 一樣捨棄OP, 採有溫暖聲音的FET分離元件A類放大電路. 而且從DAC晶片與 輸出之間都是直接交連, 所以低頻具有能量與衝擊力.
 
最後, 電源是一切音響器材好聲之源, 而電源處理正是PS Audio的強項了, 打開DL III就知道 一顆超大的變壓器就占據了大約2/3的機箱空間. 總之. 這台DL III是一台貨真價實的好物, 除了一般大家所號稱的乾淨透明的聲底外, 更添加了一般DAC機子少有的溫暖與甜味.外表有.2.3處小傷..低價出售","shipping_methods":[{"name":"宅配/貨運","fee":0,"currency":"TWD"},{"name":"面交/自取/不寄送","fee":0,"currency":"TWD"}],"lowest_shipping_fee":null,"payment_methods":["ATM轉帳"],"category_id":"2092107943","category_name":"DAC/數位音樂系統","breadcrumb":[{"id":"2092101502","name":"家電與影音視聽","url":"/tw/%E5%AE%B6%E9%9B%BB%E8%88%87%E5%BD%B1%E9%9F%B3%E8%A6%96%E8%81%BD-2092101502-category.html"},{"id":"2092105885","name":"影音/視聽/MP3","url":"/tw/%E5%BD%B1%E9%9F%B3-%E8%A6%96%E8%81%BD-MP3-2092105885-category.html"},{"id":"2092107942","name":"專業訊源","url":"/tw/%E5%B0%88%E6%A5%AD%E8%A8%8A%E6%BA%90-2092107942-category.html"},{"id":"2092107943","name":"DAC/數位音樂系統","url":"/tw/DAC-%E6%95%B8%E4%BD%8D%E9%9F%B3%E6%A8%82%E7%B3%BB%E7%B5%B1-2092107943-category.html"}],"view_count":1,"watch_count":1}
