以下是166S比165H好的部份
Acoustic noise improvement
Disc scratch free design
User protection against fragment of crashing disc
Tray in out noise improvement
Better dust proof
Protection wall on tray motor.
Symmetric suspension points ( good for vibration).
Light weight ( good for vibration)
Stronger structure against drop or shock

所以還是買166S吧

另外也可以買Pioneer DVD-120S,這台吸入式也不錯
