- #22 [audiofans], 23-02-10 17:10#20 你指PS audio?P系列都係非switching
這個是CSE既方塊圖,基本上同一部AB類擴音機冇大分別,所以並非再生電都一定係switching !

好野丶不過...... - #25 [phil.ng], 23-02-10 18:49不過 ......情人大師 講出重點丶國人只是 promoter
ANV-50 recalibrate your expectations like they did mine. The power amp section is itself a two-stage design, a small Class A stage drives a second Class A/B final output stage (the first 4 Watts or so are Class A) and the speed of the SMPS means pretty much instantaneous power delivery, all the time. - #26 [羅密歐], 23-02-10 19:22

- #29 [dy2036], 23-02-12 22:37其實講咗咁耐,噉係咪而家市面上用傳統電源嘅擴音機冇一部靚聲。

當然有丶重料丶但好貴好貴丶大牛丶大水塘丶快速整流子........
也可能好熱 - #31 [phil.ng], 23-02-12 22:59450 磅丶 48粒 4700uf 電容.....
