Not the highest quality headphone amp of course, but an improvement over using most interfaces or soundcards. You can tell its cheap, but its actually pretty sturdy and reliable. I personally think it looks cool and its actually seems a lot smaller in pictures than in person. It's not very feature packed or impressive hence the 3-star rating. Sounds alright though
impossible to find a better tube amp at this price range. i have the genelax, tung sol and electro harmonix 12AU7 tubes to roll around with if i want to change the subtle differences in audio quality. nice warm buzz to the headphone amp!
