KVG Sound

The Sensations Of Tone

Stacks Image 1209

KVG Laboratories is a dedicated group of musicians and audio engineers who are creating the finest music instruments, loudspeakers, audio equipment and sound recordings that are technologically possible. Everything we build, by hand, is Individually Custom-Engineered (ICE) for your specific requirements by founder Kermit V. Gray. We do not have a catalog of standard products because all our products are custom-made. In our experience, mass produced products require compromise, something we're not willing to do; only Individually Custom-Engineered (ICE) products can satisfy our quality standards.

KVG Laboratories is not content to build merely great instruments and audio gear. Before a design receives the KVG name, it must satisfy one or more of The Four Prime Directives:

  1. The First Prime Directive: Good enough isn’t good enough. This objective must be satisfied before any other can be. Without high quality, nothing else matters.
  2. The Second Prime Directive: Identify a common problem of music instruments, audio equipment or technique, or a desire expressed by many musician, listeners or operators, then solve the problem or satisfy the desire.
  3. The Third Prime Directive: Give the musician, listener, the audiophile, or the sound professional a level of quality, a range of musical expression, or a listening experience, that is otherwise unobtainable, unaffordable or impractical.
  4. The Fourth Prime Directive: Give the musician, listener, the audiophile, or the sound professional a capability that is otherwise not available to them.

An Uncompromising Commitment To Quality

KVG Laboratories is an outgrowth of its founder, Kermit Gray’s, commitment not to rush new products onto the market each year just to have a new product. He and his team take whatever time is needed to get the product right because they will not be not satisfied until it’s right. After all, good enough isn't good enough.

KVG LaboratoriesBe sure to visit the National Academy of the Recording Arts & Sciences, also known as The Recording Academy (the folks who bring you the Grammy Awards). Kermit is a member of The Recording Academy, so a visit to their hallowed halls is well worth your time if you're interested in the music scene.

The KVG Laboratories Sound

To achieve the highest quality, everything we make for you is Individually Custom-Engineered (ICE) for your specific needs and optimized for the specific installation in which it will be used. Mass-produced designs because mass-production necessarily involves compromise so all KVG Laboratories music instruments and equipment is hand-made to let you:

  1. discover new artistic expressions,
  2. create new sounds and tones,
  3. record with low noise and wide dynamic range, for unprecedented fidelity and musicality,
  4. enhance any sound for richness, definition and clarity;
  5. create new sounds or highly modify existing sounds in ways you might not have thought possible.

Although the big electronics companies quit researching tube electronics since tubes were pronounced “dead” around 1965, KVG Laboratories never stopped its research. We have been able to advance the design of vacuum tube audio, overcoming many of the adverse perceptions about tube sound and solving many of the limitations of transistorized audio equipment. The distinctive sound of both our tube designs and our transistorized designs is defined by our underlying design philosophy that audio equipment must not rob the music of life. This is not just empty verbage. Think about it: a live musical performance has an energy that touches each member of the audience, involving them in that same energy, sharing the same emotions evoked by the music. Music can move an audience into action, otherwise music would not be a part of almost every human experience from marriages to celebrations to political movements and even wars. Audio equipment affects more than the sound of recorded music, it can rob the music of the life if had when performed live. It is that unbelievably elusive balance everyone seeks that, once found, changes recordings into live performances appearing magically before the listener. Every nuance, every detail of the music must be let through unaltered, otherwise the balance is lost. KVG Laboratories demands that its designs allow the listener to experience that rare experience of losing themselves into the music, forgetting that they are listening to a recording, only to be jarred back to reality with a pang of sudden loss when the recording ends.

Delivery Times

Delivery times depend on the availability of the parts we need for your design, the length of time it may take to find a rare part or to have a custom-made part delivered, and the complexity of the design itself. Because each product is made by hand to the customer's individual requirements we cannot simply pull an item off the shelf and deliver it to you, so you will be advised of a projected delivery time when we discuss your order with you.
