Lehmann Audio Decade
The little Lehmann packs a vast array of options and has an astonishingly low noise floor, owing to it's manufacturer's obsession with discrete power filtration and proper internal layout.
It's one of the least expensive products in our reference room, and sits across from our $18K top-end phono stage making faces and feeling unduly confident for a reason.
