Interesting perspective given that you’re nearer the top end of digital than most of us. I hope it’s not presumptuous of me to mention that while many love the sound and consider their offerings some of the best available, DCS is also a somewhat polarizing brand.
Personally I’ve heard most of their offerings, including the Varese stack, and while that particular model is well out of my budget, not even it moved me. They are fantastically detailed and precise but more digital sounding to me than some other top end units I’ve auditioned, including the T+A unit I ultimately selected.
As you own the Vivaldi Apex and find it limiting, it wouldn’t surprise me if you find the Wadax studio to be a better solution for you.You might also want to explore MSB or Lampizator which, like the WADAX, are a decidedly different flavor than DCS. And while I haven’t heard it (yet), rumor has it that the Master Fidelity DAC and Clock are truly superb as well.
My own T+A DAC is equally involving as my vinyl rig to my ears. Indeed, on the same recording (vinyl pressing vs streamed via Qobuz) are shockingly close but for the surface noise on the vinyl. So it can be achieved.
