I have listened to both, and have considerable time with the dcs system.
They are both outstanding front ends and imminently enjoyable. I believe the dcs Elgar/Purcell rig is a bit more detailed, a bit better at placing instruments and voices in the soundstage, and is a touch more holographic in the way it allows musical notes to start, evolve and decay in free space. However, my comments on the dcs come with some reservation. And, that is, either the dcs Verona (master clock) or an Apogee Big Ben (also a master clock) MUST be employed in this rig in order to extract the superior sonics consistent with my comments. Otherwish the soundstage will be slightly constricted in width, though perhaps still better than 90% of the players on the market, and image placement will be just a bit vague compared to it's use with the master clock. Again though, even without the clock the dcs is likely more accurate at image placement that many players on the market. I would also say the extreme treble area is served with more of a natural or "analog" flow with the master clock inserted however, only in back-to-back AB'ing will this difference likely be evident. And, yet then it is still very subjective - so don't bank on this specific comment.
The Trivista is overall a touch softer sounding than the dcs but, it also has an uncanny ability to deliver music in a holographic manner. Notes and voices will start, evolve and decay in a sort of "liquid" or "analog" manner very well placed within the soundstage. Not quite a wide as the dcs but, unless you are doing direct A-B comparisons the you are not likely to focus on this difference. One might also say the Trivista is not quite as transparent a player as the dcs. But, the Trivista is a champ in the fundamental delivery of the music. The ebb flow is excellent - very musical. Every bit as good if not better than the dcs.
I predict you will be happy with both. Given the care in set-up and, assuming you employ the master clock, I would speculate that you favor the dcs. But, it's all very subjective - very fun - and very expensive.
