The Kenzie proved to be a very impressive listening experience and being part of the tour, opened my eyes to the rather welcoming nature of the Head-Fi community; which has its jerks like any other hobby but most members are more than willing to answer questions or even get together for a listening session.
The Kenzie is punchy and has cleanliness in the sound that is otherworldly, and with the extension of the notes, you get a representation of music that is incredibly solid
The Rockwell is a single ended amplifier with zero feedback, and it employs direct heated triodes for its power tubes. Like the ampsandsound Bigger Ben, it uses a 6SL7 input tube, and it is tube rectified. The out transformers are massive and over spec'd and provide five output impedances (8, 16, 32, 100, and 300). This allows you to match this amp to pretty much any headphone. Like the Bigger Ben, it has Jupiter capacitors, and input transformers, and one single ended input. Volume control is a very high quality stepped attenuator, and it has speaker binding posts on the back of it, making it an integrated amplifier.
