OP也換為ON Semi NE5532, 果不其然, 在升級完成之後, 整體的表現狂虐原廠未改的N-50.\n\n後繼的N-50A用料雖然有稍微改善, 但仍然以成本為優先考量, 現在您可以花費不多的費用將手上的播放機做一次升級, 連工帶料的費用是3000元, 細節可透過問與答討論, 刊登的價格是運費.","shipping_methods":[{"name":"7-ELEVEN取貨付款","fee":0,"currency":"TWD"},{"name":"宅配/貨運","fee":0,"currency":"TWD"},{"name":"萊爾富取貨付款","fee":0,"currency":"TWD"}],"lowest_shipping_fee":null,"payment_methods":["ATM轉帳","萊爾富取貨付款","7-ELEVEN取貨付款"],"category_id":"2092107943","category_name":"DAC/數位音樂系統","breadcrumb":[{"id":"2092101502","name":"家電與影音視聽","url":"/tw/%E5%AE%B6%E9%9B%BB%E8%88%87%E5%BD%B1%E9%9F%B3%E8%A6%96%E8%81%BD-2092101502-category.html"},{"id":"2092105885","name":"影音/視聽/MP3","url":"/tw/%E5%BD%B1%E9%9F%B3-%E8%A6%96%E8%81%BD-MP3-2092105885-category.html"},{"id":"2092107942","name":"專業訊源","url":"/tw/%E5%B0%88%E6%A5%AD%E8%A8%8A%E6%BA%90-2092107942-category.html"},{"id":"2092107943","name":"DAC/數位音樂系統","url":"/tw/DAC-%E6%95%B8%E4%BD%8D%E9%9F%B3%E6%A8%82%E7%B3%BB%E7%B5%B1-2092107943-category.html"}],"view_count":4,"watch_count":13,"hashtags":["Pioneer","N50","N50A","N30","N30A"]}
