Hello - your assessment is generally accurate. I view the lineup as follows, from warm/colored to neutral/uncolored: Asgard 2 > Jot 2 SE > Asgard 3 > Jot 2 XLR > Jot 1 > Magnius.
The Jot 2 has the best overall technicalities, including stage, and most versatility.
When choosing an amp and then fine tuning, you also have the flexibility of changing your cartridge. For example, a Grado cart (warm) and Magnius may be able to get you to a similar place sonically as an Ortofon cart (neutral bright) and Asgard 2.
I’d recommend the Jot 2 and Hart Audio modular cables that will allow you to switch between and use the single ended and XLR outputs. If not, then the Asgard 3 due to its balance of technicalities and enjoyment factor, where the Asgard 2 is more extreme in warmth at the expense of technicalities (I still found the Asgard 2 enjoyable, and it may serve as a good complementary amp). Good luck.
