Thank you all C Hing. This is my first time to post question here and you guys are so great to give me response. I will consider all the suggestion, and will go to check out CEC too.
For amp, if you choose JR combo, I will recommend you to go for Nagra + JF 825 instead of 625 based on my own experience. For DCS, I will go for Paganini transport + DAC and on hold for the clock.
