There's no reason to buy Topping anything, ever. They're horrible products. Their amps just abuse reverse feedback to achieve trivial distortion measurements while sounding like corroded engine.
Horrible take. The Jotunheim sounds a lot better than the Magnius. The Magnius is way too harsh and sounds very dull by comparison. Jot 2 is a much better simplifier, measurements don't tell the full store. Asgard 3 sounds better than the Magnius.
