Consider upgrading the Pass. Here's what AI tells us about it: The XONO is one of those beautifully over‑built Nelson Pass designs where the architecture is already world‑class, but the parts quality is the limiting factor, not the circuit.
the Pass Labs XONO can be upgraded, and when it’s done intelligently, it can perform at a level far beyond stock. . .and the pass is a great looking phono stage.
Here's BOM for your upgrade:

Alternatively, you can find a BAT VK-P5 for just north of $1000 that in stock form, will perform better than your pass; however, the you can upgrade the BAT to perform at least as well as the Luxman and in some areas bettter.
I suspect that the most cost effective approach is to upgrade what you have unless you want to move to tubes.
Bottom line upgrade your already fine unit to max out it's performance and keep so cash in your wallet.
