Similar experience here with Auralic and their Lightning DS music management software. I had Roon - loved the interface and meta data. But, when I compared the exact same Qobuz files over Roon vs Lightning DS, (no processing - so it was a fair comparison), I dropped my Roon subscription that day. LDS sounded better.
I’m guessing there are certain systems for which Roon is perfectly fine. And, there are some systems that are built around Roon. But, I would never go back. Over LDS, music is much more open - there’s just more spatial information - depth and breadth.
As I thought about it more, it didn’t surprise me, though I’m sure the 1s and 0s crowd remains skeptical. Native music management systems are built around the architecture of the hardware. Buffers/cache etc are all optimized. Roon is like MSFT Windows. It has to run across all kinds of hardware. How can it be optimal for all systems? Again, love the interface, but LDS is also more than good enough on that front. The quality of the music reproduction matters more to me. As always, YMMV.
Best,
