Bottlehead Single Ended eXperimenter’s Kit 3.0 — Great Audiophile Gift

Bottlehead’s affectionately-named S.E.X. 3.0 Kit ($539 on up) is extremely easy to build and will run any dynamic headphones – even AKG K1000s and Audeze LCD-2s – to great effect. Power output is a generous two watts per channel, so it could also drive highly efficient loudspeakers too! The big update for Version 3.0 is that Bottlehead has changed the tubes used from the now difficult to find 6DN7 to the 6FJ7. The 6FJ7 is the same tube in a different glass envelope designed to fit in a Compactron socket. Same great sound as the 6FJ7, but in a tube that isn’t being gobbled up by our competitors who have (finally) caught on to the great sound of the 6DN7.
