    nicknick ching,
Do you know is it the same DAC in AV Pre Amp 5509 and AV Int Amp 5009?
Why need to use separate pre and power amp? The power amp is only for pushing the big speaker or also can help processing? If  I only use bookshelf speaker, 5009 is enough?

5509與5009相同，基本上5009就是加了後級的5509。
分開前後級有相當的好處，例如可以讓互相的干擾減低、由兩個電源供電、樂器分隔度及彈跳力提升、背景更寧靜，甚至透過配搭不同的前、後級及線材來調聲..... 等等，不過以上的都只是相對的說法，要即場A，B比較才會聽到。
一般使用及書架喇叭，5009一部已經足夠，c/p值相對也比5509加後級高。
