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 present in a live performance. Treehaus Audiolab is the result of close friends on a quest for simply “best sound.” We suffer from Audio Mania, and our products are the fruit of this obsession.

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.

Single-ended thermionic tube amplifiers ideally suited for any high efficiency speaker. Based on the work of Susumu Sakuma, our amplifiers utilize transformer-coupled amplification stages and Japanese Finemet-Core signal transformers to allow superlative 300B performance. This architecture yields one of the purest expressions of what vacuum tubes can offer the listener.

The Treehaus Audiolab TVC-Based Preamplifier is built around the unique properties of the 4P1L, offering 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.

Our Finemet-core MC-SUT maintains all the fluidity and dynamic quality desired in serious vinyl listening; without the darkness associated with vintage irons, or the astringent nature of silver-wound cores.
