I also run the Tri-Vista DAC. I thought it sounded great with the Arcam FMJ 23 used as a transport. Then I tried out a nice used Theta Data Basic, the first model I believe, and was quite surprised at the improvement. Considerably more airspace around all voices and instruments, and greatly enriched bass, but with nice detail. By this time, I'd committed too much to new amp and speakers to take advantage of a real bargain.
Unless it quits the next day, hard to see how you can go wrong at prices around $500 USd.
