現在真係 1516
本來想買 2809,近來又想睇下 51,71 or 876,
但後兩個選擇己超出預選

哈哈 ~ 我頭一部 av amp 係先鋒 , 最後三部係天龍 ~

我理解為AB数功放有力D, 所謂"埋身", 是指喇叭出声力度勁D, 所以有"埋身"感覺

而"成個人走左入套戲入面 , ", 我覺得係各声道調較得宜令包圍感提升, 所以好似你自己係現場咁. 吾関class AB 或class D事. 如Class A ...

其實包圍感唔關部amp係用邊類,
反而要埋身和狠勁, D類應該重勁, 因為聲音收放夠快, 衝擊感自然夠
其實LX71和81較51包圍感好...好大原因係Full Band Phase Control和Phase Control既分別

But I doubt if you test in shop, will the shop really tune the AMP before giving you a try?  Or it is a matter simply of the hardware difference only.

Alzard兄有見地....
睇佢今期sell邊部la....

其實小弟家中有第一代HD AV amp---Pioneer VSX-LX50, VSX-LX60..
的確, 用Full Band Phase Control既LX60包圍感完勝用Phase Control既LX50..
聲音亦較厚暖...但埋身程度就真係差不多...

又學到野

以我有限amp design 知識, AB類於小電流時, 行A類功放, 声音会滑同定,失真小. 到某额定電流時,轉B類功放,力度大增. 但存在AB類轉換失真.

計力度應為純A類為首,但最哂電又熱. 次為AB類. 至於D類因利用IC技術達到高 ...

in my experience , class d always powerful enough and the best dynamic compare to a or ab , the only weakness was the sound quality , the sound can't be round as class a or ab .can say a little harsh, but may be it will improve soon because it still have a lot space to improve , the future may be take over by classs d if the sound quality improve saem as ab .like ICE POWER , they are one of the best company that have good skill for class d.

cake 兄, 吾好咁講. 倾下計啫.

依期pioneer大熱, 我尋日都8下走去試聽. 感覺同上次差不多. 分昕力高, 声底薄(吾怪得你話要tune亇100hz~200hzEQ).前後移動吾錯,可能你講個Full Band Phase Control有関.

我覺得phase ...

ryanenen兄,
MCACC既EQ設定入面100-200hz果度係比較低...真係唔知點解...
但一較番高D...成部amp即刻唔同晒...
所以先至話較番高D 100-200hz果度..

上次其實講漏左少少知料... , 補充番先..
Full Band Phase Control其實係高中低音都會較正Phase...唔止低音..
Phase Control就淨係低音

真係獲益不小
