Rotel Power Amplier 976

My friendhas a old Rotel six channel power amplifer 976 from his friend. He has the following question

1. Is this one is better than Marantz Power amplier Ma500 for AV front and centre channel ? ( This amp can use bridge to gain more power to 150W for three channel )

2. This amplier can use stero mode for six channel and bridge to three channel. However, he wants to know that in stero mode, each speaker is connected to +ve and -ve but when he bridge with another channel, from speaker to this amp , the manual shows thatit connects to the both +ve side of this amp ( speaker +ve to +ve of amp and -ve side of speaker connect to +ve side of amp )
is this connect ?

1.如果「正常接駁」電源線的MA500同976比,
結果會平手,
而976音樂感會好少少,
但若將MA500的電源極性倒轉,
MA500無論高、中、低音都會贏很多。

2.100分。
因為要用兩份AMP,
正常係機背會有標示,
要跟番那一個正極是正極,
而另一個正極就會變負極。
