Hi HYHY, it seems like you are looking for some quick answers here which hopefully instantly solve your issue. I think you may get disappointed in the end if you hope to get the right answers from just a few of us as we all hear things differently. There are plenty of information in the this forum, so read up more to get a better and balanced view. Of course, nothing will top hearing the gears yourself. While I agree there is no easy access to quite a number of TOTL head-amplifiers in Singapore, you will be surprised the amount of DACs you can find in Singapore, not to mention you hardly need to travel more than a hour to reach the shop. Therefore, saying Singapore is a DAC unfriendly place is as wrong as it gets, unless you stay at home all the time. Google is your friend and just put in more effort, you can easily audition many DACs. Good luck!
