If I have to pick 3 favourite features out of everything, the first one is definitely the looks and the build quality. Definitely nice that it's not just a tube preamp, but also a headphone amplifier with vinyl support. It's also nice that you can swap out the stock tubes for other tubes to find your preferred sound "flavour". The video description will have the models and full specifications of the tubes available. I would definitely change the fact that the line out should be disabled when you plug in headphones,
otherwise when you listen to headphones, the speakers also output the sound, you wont heart it, but your neighbours will. It would a be nice if preamp could also work with mc vinyl cartridges, at the moment it works correctly with the Mm Cartridge. It would be very cool if the set came with an aux cable with 3.5mm jack.
