Thanks for your reply. A little bit understand. After reading the manual of Z7 and Rotel amp, the output voltage/impedance of Z7 pre-out is 1.0V/500 Ohm and the input voltage/impedance of Rotel amp is 1.5V/32k Ohm. Is it the point what you are saying and there is no problem of Rotel amp?

今日終於有時間同精神認真比較過只用Z7推前置同pre-out用Rotel RB1080推嘅效果 (因之前全家大細病咗成個星期)，發覺用Rotel RB1080推上落動態大咗，而且細節明顯咗同聽多咗，好彩無入錯，依家真係聽唔返轉頭，為咗有更好表現，所以入多條綫
