About the VTSP-3a
The Herron VTSP-3a is a vacuum tube stereo preamplifier designed for audiophiles seeking precise and uncolored sound reproduction. It features selectable high (12 dB) and low (6 dB) gain modes for fine volume control increments, controlled by microprocessors with noise reduction measures to avoid signal pollution. The front panel includes balance and volume knobs, an oval volume level display, and pushbuttons for source selection (Video, Tuner, CD, Aux, Phono), mute, mono, phase invert, tape loop, and display dimming. All functions except balance are also accessible via a compact remote control. The unit is designed to be left powered on continuously, drawing minimal current and producing negligible heat. It offers a frequency response from 1 Hz to beyond 100 kHz, 100,000 ohms input impedance, and low distortion well under 0.01% at typical output levels. The VTSP-3a includes features such as switchable absolute polarity, full-range balance control, home theater bypass, two main outputs, tape output and loop, and gold-plated Teflon-insulated RCA connectors. It uses hand-picked components for accurate response and volume control with 100 steps. The preamplifier is praised for its clarity, minimal tonal coloration, and ability to reveal the true character of connected components without adding sonic signature. It is considered a hidden gem among high-end audio brands and is engineered for longevity and reliability. The package typically includes the preamplifier, remote, tubes (e.g., Electro Harmonix 6922EH), manual, power cable, and factory packaging.
