Brand: Vac

The VAC Renaissance 140 (mkIII-S) is a high-end stereo preamplifier created by VAC (Valve Amplification Company) in collaboration with design consultant, Siegfried Linkwitz. The mkIII-S stands for "single-ended" and refers to the fact that this version of the preamp utilizes single-ended tubes, or valves, for amplification as opposed to push-pull configurations found in many other preamps.Here are some noteworthy features of the VAC Renaissance 140 (mkIII-S):1. Single-ended tube design: The mkIII-S uses a decent balance of high-quality single-ended tubes, notably a 6H30 vit Piu, a 6C33, a 6V6, and a 6SL7, all of which are made specifically for VAC by Electrocompaniet. Nicely designed tube sockets, PCB, and point-to-point wiring provide an elegant integration of the tubes.2. Step-adjust volume control: The step-attenuator system utilized in the mkIII-S produces a consistent and low-noise control with virtually no capacitance coupled between stages, resulting in less distortion as well as an elusively detailed high-frequency response.3. Custom outputs: The mkIII-S offers a range of output options that are specific to the driving requirements of various power amplifiers, including balanced XLR, custom single-ended BNC, and vintage RCA connections that are found virtually nowhere else.4. Flexible input options: The preamp boasts a total of six inputs, which can be selected via front panel push buttons or discreet, hand-built relays. Inputs 1-3 are selectable gain—5x, 10x, or 15x—while inputs 4-6 are fixed 5x gain. The input switch can easily be adjusted via front panel controls.5. Careful construction and design: The VAC Renaissance 140 (mkIII-S) features a dual-mono construction, with a separate power supply and transformer banks for each channel. Intricate circuit board design, hand-built relays, point-to-point wiring, and through-hole components and connectors build upon the renown VAC quality and consistency in design and construction.6. Minimalist remote features: The mkIII-S includes an updated remote control that allows volume adjustments, as well as toggling between inputs, mute, phase, and sleep functions.7. Versatile, versatile, versatile: The VAC Renaissance 140 (mkIII-S) combines the best of both worlds through its use of valves in single-ended configurations—the classic, warm, detailed, and exciting sound of tubes, combined with excellent measured performance, which is very topical in modern audio technology. It is a preamplifier that can smoothly deliver the warmth, detail, transient speed, and dynamics that both music and high-end audio lovers demand.In summary, the VAC Renaissance 140 (mkIII-S) presents an innovative, modern, low-feedback, single-ended tube design packed into an elegant, well-constructed, and versatile chassis that is equipped with an impressive array of options and features. At its core, however, is VAC's dedication to uncompromising, musical sound, clear detail, and attention to craftsmanship that has solidified their position as one of the most celebrated audio companies in the world.
