Hi,
I hope to help by writing from EARxperience.
I bought the version ONE.
Obviously, everything depends on your system and expectations, but I will say that this is an excellent dac that entertains beyond its price point. I've been using it in my office system and it sounds great. Further, the few changes I've made to that system are readily heard running through the Parasound.
I'm not saying it's a giant killer, but it is a fine piece of gear.
That said, if you can afford a Comet Exogal, then just buy one. I think the Comet is exceptional and wish more would rally around it. There's one used on head-fi.
Good luck
