Basis Audio A.J. Conti Transcendence Turntable and SuperArm 12.5 Tonearm

Conclusion
The Transcendence doesn’t sound like any other turntable I’ve experienced. In fact, it doesn’t seem to “sound” at all, but rather disappears from the playback chain—providing a transparent window on the mastertape that created the LP. Through this disappearing act, the Transcendence more fully reveals the beauty and musical expression encoded in our LPs. Although you can listen to the Transcendence and identify a list of sonic attributes, what really distinguishes this turntable is the way that it conveys more music, more expression, more beauty, more musical intent. Discovering rich new meaning in well-worn LPs is perhaps the most profound testament to the Transcendence’s preeminence. I consider the Transcendence one of the greatest achievements of high-end audio, not just in turntables and tonearms, but across all product categories.

It’s impossible to consider the Transcendence without thinking about its creator, A.J. Conti. The turntable is an embodiment of the ethos he brought to his work. I’m glad that Basis named it after A.J. and chose the name “Transcendence.” It’s a fitting moniker on many levels. The turntable, and the pleasure it will bring music lovers, transcends A.J.’s time on this earth, and its sonic performance transcends not just that of other turntables, but also what we had assumed were the limitations of the LP format.
