Thanks for the information
I ended up buying Yaqin SD 32A CDP (~350usd?) since it was cheap with excellent reviews. Luckily it was a good choice, and the sound was much better than the laptop. Large sound stage, warm sound, deep bass.
Yaqin -> Yulong D100 -> Matrix m-Stage
It have an HDCD DAC built in, which is quite useful. However it doesnt do SACD...
Also, for some K2HD labelled disks, the cdp will also read it as HDCD, and I don't know why thats happening.
