For optimal headphone performance, the Icon-2 includes a discrete, high-performance headphone amplifier.
For operation as an audiophile-grade preamplifier, the Icon-2's linestage can be connected to a power amp or active speakers.
As a high-quality auxiliary power amp in a surround-sound setup, the Icon-2 can be used to drive tweeters or rear-channel speakers.

唔知香港間代理有冇
我上年有考慮過買的

Eric5cm

icon2 賣HK$2800,不如買張電腦sound card(HK$1xxx) + icon amp(HK$1600)好過,
起碼可以換op amp同換喇叭線玩.
M1賣HK$2800,M2好似賣4千幾,捨得僅係買M2,低音好Ｄ,
我用僅M1+iocn amp在70呎方問,足夠有餘,非常滿意

用有源SPEAKER 加AMP 係冇用. 用ICON UDAC2 + ACTIVE SPEAKER 仲好. 粒DAC 又勁D.
