Well, I had one and it is good. I enjoyed it when I had it.
I sold it after 4 months.
Best on the planet? I don't think soooo. Only you can determine what is best in your system. The DAC 1 has gotten rave reviews for sometime now. You also can find them used as many as 5 at a time on Audiogon. They must have sold a ton of them.
Try one used, you can always sell it for what you paid for it.
I do like my Raysonic 128 in NOS mode better.
This replaced the DAC1.
