I have had my Terminator Plus for a little over a week. I upgraded from a Terminator that had for about 10 months. I added a Denafrips Gaia to my Terminator about a month ago. This was a significant improvement to the Terminator.
My T+ is still breaking in, so I don't know how much better it's going to get, but after a week it has now easily surpassed the Terminator, which I thought was a great DAC. The biggest difference I've noticed is that recordings that I had previous thought were just not very good are now much more listenable with considerably more detail.
If you decide on the Terminator Plus, I strongly recommend adding the Gaia. I haven't actually tried the Terminator Plus without it, but the improvement with the Terminator was so dramatic that I would expect it to be a well worthwhile addition to the T+, particularly since these two devices were designs specifically to work together.
I have never heard the Tambaqui, so I can't comment on any comparison.
