The Design Concept
Behind Pendulum's Class A Vacuum Tube Products
|by Greg Gualtieri

amazing proliferation of new vacuum tube-based audio products
has, quite frankly, given many people the wrong impression about
the way tubes can actually sound. While it's true that tubes
possess a special 'character' that distinguishes them from their
solid-state counterparts, many current designs have focused more
on using tubes as an 'effect' - that is, to impart a strong coloration
to the sound. This coloration is more a function of vintage circuit
topologies and poorly regulated power supplies - artifacts of
the circuit design - than any inherent limitation of the tube
itself. Consequently, much of the clarity and detail that tubes
are capable of delivering is often masked by poor high end response,
a muddy low end and unacceptably large quantities of harmonic
distortion. Tube coloration of this sort is not necessarily a
bad thing, but those of us who use today's high resolution recording
technologies frequently require a higher level of sonic accuracy.
At Pendulum, our goal is to enhance the unique
character of the way tubes sound and minimize the sonic artifacts.
To this end, our line of vacuum tube signal processors represents
the state of the art in modern tube design. These are class A,
high headroom, short signal path, transformerless designs that
provide superior audio performance and a level of clarity and
intimacy that is difficult to describe, since most people have
never heard a tube circuit without the sonic artifacts. In addition,
all our products are hand-built to exacting standards, using
the highest quality passive components and interconnects available.
And we don't use a component just because a spec sheet says it's
the best. We carefully listen to them and always let our ears
be the judge.
encourage you to give our new line of tube products a listen
and let your ears be the judge. We think you'll change your opinion
of how tubes really sound.
