Welcome to Treehaus Audiolab
Our products have the same singular goal: create captivating sound that does not leave the listener yearning for more. Music is reproduced naturally, with the tone, nuance, detail, and energy that is present in live performance. Treehaus Audiolab is the result of close friends on a quest for “best sound.” We suffer from Audio Mania, and these works yield the fruit of our obsessions.

Field Coil Loudspeakers
Bespoke, field coil high efficiency full range speakers. Built around world- renowned drivers by Atelier Rullit. Rullit utilizes vintage Klangfilm-era cores, reimaging them through a meticulous rebuild process that immediacy, detail, and ease that simply does not exist in many drivers. These drivers are then housed in a unique open baffle design that utilizes the acoustic strengths of large live-edge wood slabs, asymmetric component layouts, and the utmost attention to how details affect the sound produced.

TVC-Based Preamplifiers
Built around the unique properties of the 4P1L, this preamplifier offers an incredible sonic presentation. Custom line-out transformers utilize Finemet cores. Volume attenuation is performed by Finemet TVC (Transformer Volume Control). This method of attenuation does not lose audio information in the process of attenuation. All volume levels possess the same level of detail and energy.

Sakuma Architecture DHT Amplifiers
Single-ended thermionic tube amplifiers ideally suited for any high efficiency speaker. Based on the work of Susumu Sakuma, our amplifiers utilize a directly heated triode driver interstage coupled to a directly heated triode acting as the power tube (801/300B). This architecture yields one of the purest expressions of what vacuum tubes can offer the listener.
