Paying $340 for something with built-in intentional distortion seems insane to me.

$339.99-$25, and welcome to the world of tubes. A land where THD is just a number that doesn't really mean anything.

Bought this as a pre-amp. For $61, can't imagine better performance.

Liquid spark measures really well - https://www.audiosciencereview.co...-amp.5224/

Liquid platinum gets a less favorable review, relatively low tube-induced distortion if for some reason you want tubes but not much impact from them (I could understand this wrong) - https://www.audiosciencereview.co...view.7036/
