Then you did not listen to an AB comparison between Rossini and Vivaldi. Given the huge price difference, I did. I traveled to dCS in Cambridge (UK) and we compared the product lines, swapping them out on the same rack, with all other equipment (Transparent cables, d'Agostino power amps, Wilson Audio loudspeakers) remaining the same. Rossini sounded amazing. What could Vivaldi possibly improve? In fact, everything. Starting with the scale and depth of the presentation. I bought the Vivaldi stack. However, when installed at home and compared to my vinyl setup, Vivaldi fell short by a serious margin. I gave up on digital. That was in 2016. Then, 2 years ago, the Vivaldi Apex upgrade came along. I gave it a try. A monumental improvement. Then I upgraded my cables loom. Better still. I spare you many more tweaks. Finally, I installed a Nordost QB10 distribution block. We are getting there. However, when I removed the rubber discs from under the feet of the QB10, digital sound finally came of age! I mean, this verges on the absurd. But this is the reality of digital how I experienced it. Digital is very sensitive to power management, racks, vibrations and resonances. And a 2012(!) design - with one upgrade in 2022 - can still deliver the goods if properly supported (what I call the Hifi "infrastructure"). Of course, my vinyl setup also improved quite dramatically, but from a position of already excellent sound presentation. It remains the reference, but digital has almost closed the gap. What is the moral of this story? Invest in Hifi infrastructure! It is the best audio investment you can make, especially if you can get in 2nd hand.
PS: for completion, I also auditioned Vivaldi's predecessor - Scarlatti - at home.
