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.
