As long as you realize that for good two channel sound you need to do all three then do it in whatever order is easiest for you. Finding used Denafrip's DAC's or current Auralic streamers used is not a common and when they do show up they sell almost immediately. For those you may need to bite the bullet and buy new. On the other hand used preamps are plentiful so you have a better chance of finding something that fits your needs with a little effort and research. The G1 or even the Lumin U1 Mini are great choices and those telling you the Node 2CI are all you need are fooling you and themselves. I bought one for my daughter and tried it in my system in place of the G1 late last year and there was no comparison. This was a repeat of a head to head comparison I did five years ago against the Aries Mini and the results were still the same, the Auralic won.
