Chapter 12 - SPECS VERSUS PERFORMANCE: (Continued)

When evaluating and choosing components, specs may be used as a starting point to reduce the number of options to a realistic figure, but then it becomes vitally important to remember how these components will be ultimately used: for the joy of music in a home environment, as opposed to on a test bench in an anechoic chamber.

We thus encourage you to trust your dealer’s advice with regard to system compatibility, which is based on a combination of elemental specs and the specialty retailers’ experience. This will ensure a good match, beyond which this owners manual contains everything you need to know about operating your new component.

It is a sad truth amongst audiophiles that, during our sometimes compulsive search for perfection, we unlearn the art of listening from the heart and act like judges during a music competition or audition, looking for things to criticize rather than allowing the music to take a hold over our emotions.

So we haven’t included the usual spec sheet with this manual. Besides the reasons already given, the unique flexibility of the TIGRIS would necessitate 12 sets of most measurements to address the effects of all possible settings - frankly more information than we think meaningful.

We are hoping that instead, you trust your ears and your heart’s response that the TIGRIS delivers where it counts: to help create the illusion that Louis Satchmo Armstrong or Sasha Heifetz ( or any of your favorite musicians ) have, magically, been transported into your living room for a private performance at your beck and call.

If you can close your eyes and see the performers with your ears as if they were truly there with you, living and breathing and playing, then our specs have succeeded.

Vacuum Tube Audio specifications

Mesa/Boogie is a revered name in the world of vacuum tube audio, renowned for its high-quality amplifiers that have shaped the sound of modern music. Founded in 1969 by Randy Smith in California, Mesa/Boogie began by transforming Fender amplifiers into customized, high-gain models, ultimately gaining a reputation for producing powerful, versatile, and low-noise amplifiers. The signature sound of Mesa/Boogie is characterized by a complex harmonic richness, warmth, and clarity that resonates with guitarists and audiophiles alike.

One of the standout features of Mesa/Boogie amplifiers is their all-tube design. Utilizing vacuum tubes as the primary amplification source, these amps deliver a dynamic range and tonal complexity that solid-state amplifiers struggle to match. The quality of the tubes used, often hand-picked or specifically designed by Mesa, contributes to the unique audio characteristics of each model. The use of EL34, 6L6, and 12AX7 tubes in various configurations allows for a range of tonal options, from lush cleans to searing leads.

Mesa/Boogie amplifiers are also distinguished by their innovative technologies. The brand pioneered the dual rectifier system, which allows players to switch between tube and solid-state rectification. This feature gives musicians the ability to tailor their sound to preference, enhancing the responsiveness and feel of the amplifier. The Contour controls found on many models further exemplify Mesa’s commitment to versatility, allowing for fine-tuning of EQ settings that adapt to different musical styles.

Another hallmark of Mesa/Boogie designs is their attention to build quality. Each amplifier is crafted with robust materials, ensuring durability and reliability even in demanding performance environments. The custom cabinets and speaker selections are optimized to complement the amplified tone, providing a cohesive sound that resonates in live settings.

Mesa/Boogie’s reputation is enhanced by their extensive lineup, including the Mark series, the Rectifier series, and the Lone Star series. Each line caters to different playing preferences and styles, from jazz to metal. The versatility of these amplifiers makes them suitable for diverse genres, allowing musicians to explore their sonic identities.

In conclusion, Mesa/Boogie remains a leading force in vacuum tube audio, combining traditional craftsmanship with cutting-edge technology. Their dedication to quality, innovation, and tonal versatility ensures that they remain a favorite among guitarists seeking the ultimate sound experience. Whether in the studio or on stage, Mesa/Boogie amplifiers continue to inspire musicians to push the boundaries of creativity.
