Vincent Audio, renowned for its high-fidelity audio components, has introduced the SA-T7 Diamond Tube Preamplifier, a limited-production masterpiece that incorporates ultra-rare Telefunken tubes. Priced at $3,995, this latest offering from Vincent Audio is poised to captivate audiophiles with its exquisite sound quality and unique vintage components.

The SA-T7 Diamond Tube Preamplifier is built around prized German Telefunken PCF803 tubes, a find so rare that it prompted the development of a new version of the SA-T7 by designer Frank Blöhbaum. These vintage tubes, manufactured decades ago, contribute to the amplifier's impressive sonic characteristics, offering a level of musicality that is exceptional.

Featuring the acclaimed audiophile-grade circuitry found in its predecessors, the SA-T7 Diamond sets itself apart with its use of Telefunken tubes and a built-in Bluetooth receiver. According to Steve Niemi, Director of Global Sales at Pangea Audio, LLC: 

“The SA-T7 Diamond represents a once-in-a-lifetime opportunity to experience one of the most esteemed tubes in audio incorporated in a product that is a perfect match for their unique characteristics, no fewer than four PCF803 tubes contribute to the outstanding sonic characteristics of the SA-T7 Diamond.”

Designed for pure audio transmission, the SA-T7 Diamond Tube Preamplifier boasts a BestPentode-circuit developed by Mr. Blöhbaum, which eliminates electrical current noise often associated with pentode tubes. This innovative circuitry should ensure higher gain with less noise compared to conventional triodes, resulting in pristine sound reproduction.

The preamplifier offers a wide range of connectivity options, catering to both analog and digital audio sources. It includes six stereo RCA-type connections, one Toslink optical digital connection, and one coaxial digital connection. Internally, a PCM 5102-based DAC provides high-resolution performance at 24-bit/192 kHz.

With Bluetooth 5.0 capability, users can seamlessly stream high-resolution audio files to the SA-T7 Diamond, expanding its versatility and convenience. Moreover, the preamplifier features low-noise power supply couplings of the BestPentode stage, which should provide optimal performance and fidelity.

Vincent Audio's dedication to purity and transparency in audio transmission is apparent in the development of the Vimala module, a proprietary component designed to improve the performance of the SA-T7 Diamond. This module, named after the Sanskrit term for "pure, transparent, clear," should further boost the preamplifier's sonic capabilities.
