Kenzie Integrated

The goal of the Kenzie integrated was to bring the ampsandosund SET sound back to a more paired back selection. How full, rich and dynamic can a simpler stereos sound. By providing a single integrated solution, the warmth and detail of the Kenzie circuit is transplanted into an accessible package suitable for offices or more distilled systems.  

The Kenzie Integrated is a perfect companion to so many of the classic high efficiency speaker that exist from Zu, Klipsch, Altec, Ojas and so on. In the nearfield, we have paired with KEF LS50s and LS3/5As.

To keep the original footprint we opted of a single ¼” headphone jack and a pair of chunky 5way speaker terminals.

The Kenzie does not use a voltage network to impart a sonic signature rather it directly couples the output transformer with a spec’d secondary impedance. and has more than enough power to drive even the most difficult headphones. We chose 100ohm tap for the widest variety of headphones; everything from Grado Labs, HiFiMan, Audeze, MrSpeakers, Sennheiser, and Beyerdynamic.

The Kenzie showcases the transformers on the chassis to frame in the unique 1626 single-ended tubes. We have included an Alps volume pot to allow attenuation and simplify the signal path.

The Kenzie is one of the sweetest-sounding headphone amplifiers on the market. The 1626 is commonly referred to as the “Poor Man’s 300B”; offering a similar level of warmth, texture, and soundstage depth.

The 1626 is a WWII-era tube that was used as a transmitter tube in radar installations. The design is shy on pure output, but offers layers of texture and drive, and is paired with a massive choke and robust output transformers for ultra-quiet operation. As with all of our products, parts selection was crucial during this build and each chosen not for price, but for best quality and synergy.
