先锋公司的PD—T303型CD唱机社会拥有量大,然而在欣赏它时,发现其音质并不是想象的那样美。打开机壳,发现该机所用电源、运放IC、电容都不够Hi—Fi化,于是深感摩机余地颇大,摩机后音质定能进一步提高。该机的D/A转换器为LC7881,其性能与高级DAC摩机板上的PCM1710、PCM1712等相距甚远,但基于成本和方便的考虑,对LC7881的打摩暂予放弃,仅从以下几个方面进行摩机。
Pioneer’s PD-T303 CD player social ownership of large, but when you enjoy it, you find that the sound quality is not as beautiful as imagined. Open the case and found that the aircraft power supply, operational amplifier IC, the capacitor is not enough Hi-Fi, so deep sense of motorcycles quite large, the sound quality after the motor can be further improved. The machine’s D / A converter for the LC7881, its performance and high-level DAC motorcycle board PCM1710, PCM1712 and so far apart, but based on cost and convenience considerations, the LC7881’s moratorium temporarily give up, only from the following The aspects of friction machine.
