At VTL we have developed a full range of reliable and high-performance
tubed electronics to satisfy your taste for a truly high-end audio
system. To help you select the best VTL product(s) for your
audio and home theater needs, the following synopsis of the different
product categories that we offer will help you decide which system
performance level will best fit your needs.
We believe that the best sounding system is one where each of the
components in the entire system are well-matched to work synergistically
together as a well balanced system. In particular, we believe that
the matching of the amplifiers to the loudspeakers is the most critical
link to a musically satisfying system. You may wish to consult our
general guidelines for system matching
for further details.

assist you in putting together the most musical high-end audio/video
system to best meet your requirements. Please check the

Multi-function integrated amplifiers are similar to stereo receivers,
in that they are usually specified in systems that have a prerequisite
for simplicity and limited space availability. Integrated amplifiers
offer the shortest link between music source and output device,
with a minimum of interconnect cables and rack space required, and
usually offering a headphone output for personal use in smaller
The signal path is simple and direct, with a minimum number of
gain stages. The signal path is usually source component to power
amplifier (which has the volume control), and power amplifier to
loudspeakers. This simplicity means not having to be concerned with
impedance matching between components, and the sound is therefore
purer with less inter-stage buffering involved.
With this minimalist approach the integrated amplifier acts as
the primary electrical conduit between your music source, (e.g.
CD, tuner, tape, etc.) and your loudspeakers. In such a system just
one power switch activates the whole system, with minimal setup
The VTL IT-85 integrated amplifier
has both a fully active high end preamplifier and power amplifier
on one compact chassis. It offers the performance and features of
high end separate components, with the space-saving approach of
If simplicity of operation with high performance sound is key
in your system selection criteria, then the VTL IT-85 Integrated
Amplifier is the ideal product for you.
For more advanced system users phono capability is available with
the addition of the (separately available) VTL TP2.5 stand-alone
phono stage. Further system expansion is also available with the
addition of either a powered sub-woofer or a second amplifier connected
to the IT-85ís pre- out in a bi-amplified system (the pre-out is
precisely gain-matched to properly interface with the VTL
ST-85 in such a horizontally bi-amplified system).
If improved system performance is a key factor in your selection
process, then the separates approach is usually the most suitable
choice. Often this approach is chosen for the higher performance
and lower noise level attained by separating the power supplies
for each gain stage. Think of separates as taking a receiver and
separating the preamplifier (volume control and source selection
functions) and the power amplifier sections.
The benefit of this approach is that better separation between
gain and current functions is attained, as the power amplifier current
demands on the power supply will not be able to affect the fragile
The preamplifier functions to select the desired source component,
and to provide the user with a volume control with which to be able
to vary the sound level of the whole system.
Preamplifiers are required for pre-amplifying the small source
signal sufficiently to be able to drive a power amplifier. The consideration
of this component is critical, as it is usually the first component
to have the greatest effect on the source signal.
Preamplifiers may also be required to drive a long cable to the
power amplifier, or a low impedance at the power amplifier. Not
taking either of these considerations into account in the design
of the preamplifier could result in seriously degraded sound quality.
Another consideration is that different technologies may be desired
for their best properties in different areas of the playback chain.
For example, the user may prefer the efficiency and current capability
of a solid state power amplifier, to which the warmth and musical
tonality of a tube preamplifier may be added, (or vice-versa) for
a system with the best of both worlds.
The VTL Preamplifiers are both
designed to deliver outstanding performance driving long interconnect
cables and low impedance power amplifiers. The VTL preamplifiers
both offer superior sonic performance, intuitive user interface
and many other features. Our preamplifiers are also ideally suited
for first-time tube users, as they require little to no maintenance.
Power Amplifiers are required for turning the voltage signal into
current to drive the loudspeaker. The function and interface of
the power amplifier to the loudspeaker is potentially much more
complex than that of the preamplifier, as it involves more interaction
considerations that change under dynamic conditions. Loudspeakers
often change their characteristics with changes in volume and/or
frequency, and the matching of the power amplifier to the loudspeaker
load is therefore critical.
Stereo amplifiers save space, offering two channels of amplification
on one chassis. If proper consideration of the power supply is not
taken into account the two channels can interact with each other
and degrade stereo performance.
The VTL Stereo amplifiers
have separate power supplies, offering channel separation that rivals
that of most monoblocks.
We offer two stereo power amplifiers, with different sonic characteristics
and different capabilities with different loudspeakers. The VTL
ST-85 is designed for small stand-mounted mini-monitors with speed
and musicality, while the ST-150 is designed to drive small floorstanding
loudspeakers with ease and definition.
Monoblocks offer ultimate channel separation, and can be placed
closer to the loudspeakers for minimal current loss through the
loudspeaker cables, and minimal interference between power amplifier
and source components. VTL Monoblocks can also be purchased in single
units, for use in multi-channel systems.
We offer three series of monoblock power amplifier, for greater
resolution in all audio systems, and proven ability to drive a wide
range of loudspeakers.
Fast, musical sound in a space-saving chassis: The VTL Compact
monoblocks have our smallest compact chassis and main power supply,
with power outputs from 25 watts to 125 watts per channel. They
are designed with the first time tube user in mind, and offer
an easy transition to the joys of tube equipment ownership for
the music lover and beginning audiophile, as well as for the home
High resolution system in large spaces need greater power to
reach their full potential. With double main power supplies, a
separate power supply for the input stage, and greater musical
definition, which is derived from the VTL (proprietary) Signature
output transformer, the VTL Signature monoblocks offer extremely
high power in a reasonably sized 19Ē chassis. Power ratings range
from 185 watts to 450 watts per channel.
Ultra high current and power in a double-decker chassis: Near
limitless power from completely isolated power supplies to meet
any systemís demands. The VTL Reference monoblocks offer our very
largest power supply: a gargantuan supply on its own separate
dedicated chassis, with a soft start for each channel. Power ratings
are from 750 watts to 1250 watts per channel, these components
are capable of driving the larger loudspeakers to a convincing
level of realism with musical detail and unflinching power.
Built and factory installed for those whose primary relaxation
is listening to music and who demand the most that any music reproduction
system can yield, the VTL Reference series components truly represent
the pinnacle of power amplifier design.
