Class D power amp to save space

rklpoon

Itchy to add a stereo power amp, but space is a limitation, so resort to class D , researched and found the following Calyx amps for comment, thx.

好耐之前都試過玩Acoustic Reality 1001 Ref monoblock , 的確係又平又好聲!

Agree that small size not only limited to Class D amp. A few example in the market such as ISEM Audio from France.

因為Class D主要都是低價的新機，早一段時間有些網上打手把Class D吹到上天，以為1,000元的Class D可以比得上萬元級的Class AB。
結果嘛……一分錢一分貨的規則還是沒有例外的，反而令一堆人對Class D有了戒心。

其實Class D在它的價位的確交到功課，只是不要期望可以越級挑戰吧。

另外，有人提過Class D由於用上PWM放大技術，輸出的訊號跟傳統Class AB是有所不同的。
有人擔心Class D關機時高頻AC漸漸降低電壓，長久以來會令喇叭磁鐵退磁，也是另一個讓部分發燒友不喜歡Class D的原因。

最緊要好聲,這類d可以好好聲,

最弊呢d class D 賣價同傳統Class AB 一樣貴! 所以某出名牌子最後因唔銷得要妥協做番AB

How about this one ?

A high-end and high price Class D power amp. using Hypex Ncore technology.  Rumours is Jexx Rolxxx is developing a new Class D amp. with the same technology.

$5k 至10k? 得唔得?

我自己用ONKYO A5VL
CLASS D 40W
雙牛

個人覺得幾千蚊入面
CLASS D 只要設計不差
電容同隻牛都OK的話

控制力同控動力會比一般AB既好
冇咁易腳軟
但係聲音就要睇廠商設計了
好似我部機咁
係偏薄偏硬
當初2千幾蚊特價買番呢
比D心機玩又覺得唔差

我用NEAT MOTIVE3喇叭
本身驅動力要求不會太高
而我對低音推得出唔出又唔太在意

試完ATOLL IN200同KRELL 300V都完全冇興趣換AMP
除非喇叭需求更大
