A Word About Tube Research Labs, Inc.

Tube Research Labs is an audio company dedicated to the manufacture of the finest preamplification and power amplification products possible. Every product Tube Research Labs manufactures meets exacting physical and sonic standards.

From the sophisticated circuit topology employed, to the finest parts available, to the extraordinary craftsmanship in construction, these products are truly unparalled.
Sonically, every product combines power with musicality, extended frequency response with superb dynamics and the ability to create a soundstage image that is like real music.
Characteristic of every Tube Research Labs product is the use of point-to-point wiring techniques and hand assembly. No printed circuit boards (PCB's) or transistors are used in either the amplification circuits or the power supplies.
Tube Research Labs typically does not publish traditional measurements on its equipment's performance. These measurements illustrate how machines hear, not how humans hear. We probably are years away from having measurements which we can really associate to or correlate with the listenability of a device.
In order to appreciate Tube Research Labs' products, they must be measured by the most sophisticated measuring instruments there are--the ears of discerning and discriminating listener.
