PTP doesnt mean it sounds better it just means if a component like resistor or capacitor breaks it's easier to replace it.
yes in fact, PTP will not make the amp sound better. but PTP is more easy to repair if the amp get error. and i like PTP, because it is more beauty.
Pcb:容易量產、造價便宜(組裝較快)。 Ptp:容易維修、造價較貴(組裝耗時)。 兩者設計時都該盡量避免電路相互干擾。 材料不同當然會影響音色。 所以pcb也可以改用好的材料,線路安排得當的話聲音也不差的。
