Ching,SACD是約高於現時普通 CD 四倍採樣另外一種音樂媒體格式,外型跟CD一樣,可以support到7.1 analog output或通過HDMI用LPCM到AV Amp播放,理論上音樂表現會比一般CD好,不過當然要睇埋其它因素。其實我唔係喱方面專家,只有幾隻SACD而已,詳細你可以睇以下網址
Super Audio CD (SACD) is a high-resolution, read-only optical audio disc format developed by Sony and Philips Electronics, the same companies that created the Compact Disc and the S/PDIF specification used in digital audio cables. SACD is designed to provide high-resolution audio in both stereo and surround sound modes. SACDs use an audio format called DSD in addition to an optional CD-compatible layer using traditional PCM.
Introduced in 1999, SACD has not been accepted by the mainstream market, but continues to thrive in the audiophile community with new SACD recordings and players being made.[1]
要睇埋套架生先知,例如Amp同喇叭咁!好似我就用O記606 AV Amp,佢裏面用緊嘅DAC級數比83(se)為低,我會用83本身直接解碼,由佢後面嘅7.1 analog out直駁到Amp做放大,而不用Amp內部DAC做解碼,對我嚟講就絕對值得upgrade。仲有就要睇埋你對畫質要求嘞,83同9500都係中價機種,佢哋都有獨立嘅video chip做畫質提昇,就好似noise reduction、1080p24倍線……等等,我想單機比較83同9500會優勝於s470。
