My minimal audio system is completed

Finally, I can play CD with my new toy and output to active monitor. This is really a painfull experience. Normally, an amplified output signal cannot used as line-out. I did great search on any HiFi shop and no one think it is possible or it will have great distortion. Lastly, I found a rare HiFi accessory in ebay that did the exact function for high power rated amplifier. This precious blackbox is right behind my CD player in the picture. The sound may not at top quality but I have no complaint now.
