Some updates to my FrankenFiiO collection. The V2 is now been turned into a V4, with the V3 serving as the one I actually use. The V4 was just a project to see if i could actually fit an amp inside a pice of wood 18mm thick. Turns out I can.

V3 has an integrated LOD, which makes it so small and easy to use. The V4 is currently drying off some varnish so the color in these pictures aren’t accurate.
