Vincent Audio Adds Upgrades to SA-T7 Tube Preamplifier

Modifications include adding Bluetooth and updated cosmetics.

Vincent Audio has announced the availability of the SA-T7 MK tube preamplifier, an update of the SA-T7. The new SA-T7 MK features the same audiophile-grade circuitry and sound quality as its predecessor, but with the added benefit of a built-in Bluetooth receiver.

Available in both black and silver, the new SA-T7 MK (MSRP: $3499.95) features the original circuitry as the previous version, with the same sonic output. Linear amplification is combined with extreme low-noise characteristics thanks in part to the BestPentode-circuit that eliminates the electrical current noise often associated with pentode tubes.

The BestPentode stage employed on the SA-T7 MK boasts a higher gain with less noise than comparable triodes. The tubes, including 85A2, 6SCH9P, and 6SCH51P grid pentodes, are notable for amplifying high-frequency signals.

The SA-T7 MK features connections for a wide range of analog and digital audio sources, accommodating both analog and digital. Included are six stereo RCA-type connections, one Toslink optical digital connection, and one coax digital connection. Internally, there is a PCM 5100-based DAC that provides 24-bit/192 kHz performance. Compatible audio formats include WAV, FLAC, APE, LPCM, MP3, AAC, AC3, and WMA music files.

The addition of Bluetooth 5.0 allows listeners to wirelessly stream high-resolution audio files to the preamplifier. In addition, the front panel received a cosmetic upgrade, with a new modern, elegant appearance.

Extremely pure audio transmission is accomplished with a low-noise power supply couplings of the BestPentode stage. Vincent Audio developed a proprietary module for this stage, called Vimala, the Sanskrit term for “pure, transparent, clear.” A second gain stage, featuring the 6H9P, 6H51P, 6S3P-EV, and Vimala modules, affords precision control over treble and bass, though tone controls can be bypassed in order to hear the purest music signal.
