SONY MDS-JA50ES SONY ES級頂級MD座機，有獨立DAC功能， 因雷射頭已老化，當純DAC賣， 8888元即售，以其用料可謂十分超值。 AUDIO AERO PRIMA 24/192 DAC 輸入端子齊全BNC, RCA, AES/EBU, AT&T and TOSLINK全包了!訊噪比高達125dB! 規格見:http://www.audiofederation.com/dealership/audioaero/original-index.htm "Prima D/A Converter 24/192 has been designed with the idea to equal the new digital formats. Therefore, Audio Aero included the state-of-the-art in digital processing : the exclusive STARS ® process (Solution for Time Abstraction Re Sampling), a combination of very high speed 192 kHz RE-sampling (a new jitter free clock is created), 24 bit re-quantization and signal enhancement techniques (extraction of “hidden” information from 16 bit data, improvement of dynamics, precision, soundstage and details), developed for Audio Aero by Swiss company Anagram Technologies SA. The core of the system is a 32 bit floating point SHARC DSP which by performing hundred millions of calculations per second, rebuilds a high precision 24/192kHz signal, independent from the input clock, and keeping total dynamic range in all stages. Then, after a 1024 times up-sampling on demand, D/A conversion is performed at 6,144MHz by the latest advanced segments 24 bit / 192 kHz DAC from Burr-Brown. The analogue stage features sub-miniature tubes and high precision buffer for a perfect match between high-tech digital treatment and musicality. " 發售當時定價高達USD $3990 補上Audio Aero的相關介紹 http://www.hifigallery.com.hk/tc/Products_Brand.asp?bld=29 Audio Aero設計與眾不同之處，就是獨家STARS數位處理，也就是Audio Aero註冊專利的演算法（Re Sampling），包括高速192kHz昇頻、24 bit重新量化演算與訊號強化，技術內容頗為複雜，這可是瑞士Anagram公司特別為Audio Aero開發的專屬技術。 STARS數位處理的晶片使用高速32Bit SHARC DSP，重建24bit/192kHz數位訊號，然後執行1024倍昇頻，數類轉換器則以6.144MHz超高頻執行24bit/192kHz解碼。獨家STARS加上24bit/192kHz解碼之後，還有獨門功夫，就是使用6021W軍規管執行類比放大，用真空管溫暖的音色，增添柔美的魅力。 4/25 DAC聚會 http://www.andaudio.com/phpbb3/viewtopic.php?f=10&t=81316 售28888元(自取佳) Audio-Technica ATH-A100Ti http://www.audio-technica.co.jp/products/hp/ath-a100ti.html 2001年生產販售，售價33000日幣，限量3000支 為鐵三角40周年紀念機，採用與W2002相同單體 迷人的中頻與低頻表現，連iPhone都推的很不錯 為典型的老鐵女毒聲，在日本的網路評價也很好 歡迎相約試聽，美品一支售7000元含運(7-11自取) Deff Deep Bass DDA-i10RCBK小耳擴 低頻強勁，控制方便的iPod/iPhone/iPad専用小耳擴。 勸敗文見此：http://beta.imacguru.com/?p=22549 面交1500，7-11到店取貨算1550，特價出清。 magic.music@gmail.com
