EX-DEMO UNIT – includes box and power supplyThe Tube MP is the world's most popular external tube microphone preamplifier. The TEC Award-nominated design of the Tube MP allows you to achieve professional studio-quality results at a fraction of the cost of comparable equipment. The Tube MP’s hybrid design adds warmth and body to the signal while maintaining high audio quality and exceptionally low noise. While primarily designed as a microphone preamplifier, the Tube MP also serves as an excellent direct box—matching impedance, amplifying, and enhancing the sound of any instrument connected to it. The Tube MP delivers superior performance and sound quality compared to the built-in preamps found in today's low-cost mixers and multitrack recorders. Professional sound quality combined with professional features—such as a hand-selected 12AX7A tube, phantom power, and phase reversal—has made the Tube MP a staple in thousands of studios worldwide.Note: We ensure every shipment in order to protect our customers and the purchasings.

Condition is unknown, so the US$102 ask lands right at the median of recent comps and looks fair rather than flashy. With a 25th percentile at US$80 and a 75th percentile at US$2,999, this sits comfortably in the normal buy zone for a used tube preamp of this type.
That makes it worth considering if the unit is clean, quiet, and fully functional, especially if the seller can confirm original tubes, power supply, and unmodified internals. Art Audio gear has a loyal following for a lively, spacious presentation with real tube character, so a well-kept example at this price is a sensible entry point rather than a gamble.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
# Art Pro Audio Brand Description
Applied Research and Technology (ART) was founded in Rochester, New York, by a team of five engineers—Phil Betette, Tony Gambacurta, John Langlouise, Richard Neutrour, and Terry Sherwood—who previously collaborated at the legendary effects pedal manufacturer MXR. The company emerged from a philosophy of engineering excellence and practical design, prioritizing reliability and affordability over unnecessary complexity. This heritage of precision and innovation has defined ART's trajectory since its inception.
ART initially established itself in the professional recording market, launching with digital reverb units that set the tone for the company's technical focus. The brand achieved widespread recognition with the Tube MP, released in 1995, which became their signature product and remains central to their identity. The company has maintained a strong presence in professional audio equipment, particularly in signal processing and tube-based preamp technology, serving both studio professionals and discerning home audio enthusiasts.
ART occupies a distinctive position as a mid-tier to professional-grade manufacturer with particular strength among recording engineers and vintage audio collectors. The brand is respected for engineering integrity and sonic character rather than mass-market appeal, positioning itself as a specialist choice for those seeking transparent, reliable equipment with genuine tube circuitry. Their reputation rests on decades of consistent product performance and a loyal following among audio professionals who value substance over marketing.
