NUFORCE ICON 1

好正.

小弟係NOTEBOOK --> E-MU 0204 USB --> ICON --> KEF CODA 7

剛又試左 NOTEBOOK --> ICON (USB) --> CODA 7

等等寫感受, 我都好耐沒來這區啦.

其實我以前都好鍾意打電機GAME, 到依家都成日上來.

自己好鍾意一塵不染的HIFI主意, 做人能還原幾多自己呢? 那個最本相自己, 排除所有不良的影響, 再而感覺到SOURCE的同在...

SORRY 好似講到好遠.

Q1: 一返來馬上要試係LINE OUT未經放大的SIGNAL比ICON是否夠力推書喇叭呢? 以及那對專用蕉插喇叭線平安否, 因為二手買來散裝沒了包裝, 有風險.
R: 答案是夠推, 線也沒有問題

Q2: 為何選ICON?
R: 冇, 因為想買部擴音, 比新電視用(未買). 較早前買左樂之邦MD10, 都是二手. 新家入伙用. 因為新家都係細, 所以唔係好想買大電流的POWER AMP.

Q3: 0204 USB-->ICON 效果如何?
R: 正呀,聽緊. 柔和左,

Q4: ICON USB 做埋如何?
R: 出唔到24BIT OUTPUT, 唔知係USB CHIP 定DAC食唔到. 分析力唔係0204 (AKM4396)果班. 果背景暗晒.

好得意, 佢地2個有好似的地方, 都可以食USB, 都可以做耳擴. 但強項係一個做耳擴/擴音, 一個做USB至DAC果段.

Class-D amp
其實係咪前級?

It can be a power amp indeed.

https://en.wikipedia.org/wiki/Class-D_amplifier

A class-D amplifier or switching amplifier is an electronic amplifier in which the amplifying devices (transistors, usually MOSFETs) operate as electronic switches, and not as linear gain devices as in other amplifiers. The signal to be amplified is a train of constant amplitude pulses, so the active devices switch rapidly back and forth between a fully conductive and nonconductive state. The analog signal to be amplified is converted to a series of pulses by pulse width modulation, pulse density modulation or other method before being applied to the amplifier. After amplification, the output pulse train can be converted back to an analog signal by passing through a passive low pass filter consisting of inductors and capacitors. The major advantage of a class-D amplifier is that it can be more efficient than analog amplifiers, with less power dissipated as heat in the active devices.

Thanks
