The HV-Series

Within just two years the HV-series has developed into a line of high-end electronics which has gained some of the finest reviews and assessments world-wide.

In that short time it has made T+A the leading high-end manufacturer in Germany.

The HV-series first appeared in 2013, and was based on their thirty years of experience in the development and construction of first-class transistor amplifiers and valve devices.

The new series incorporates a revolutionary concept combining the sonic and technical advantages of both technologies, at the same time avoiding the inherent disadvantages of present-day valves.

The HV = High Voltage technology is employed in the amplifier stages of all the machines in this series, and is the secret behind their outstanding performance and sound quality.

The source devices of the same series are just as uncompromising and superb as the amplifiers.

They represent absolutely the highest level in the processing and reproduction of all digital sources.

Design Philosophy

T+A HV Room

The HV-series is the true embodiment of the original meaning of the term ‘high-end’: innovative technologies, uncompromising construction and absolutely peak performance.

For the HV-series they developed a whole raft of unique and superior technologies which are available exclusively to T+A.

Amplifier stages work at very high voltages, and are therefore inherently more linear in character than conventional circuits.

The players feature separate high-performance converters for PCM and DSD, digital and analogue signal processing are kept consistently separate from each other, and specific subassemblies are galvanically isolated.

All devices are fully channel-separate and designed on the double-mono principle.

They are of entirely discrete construction, without operational amplifiers (op-amps).

Amplifier output is more than 500 Watt per channel.

The mechanical construction of all cases is extremely sophisticated, based on an internal framework of 10 mm thick machined aluminium plates.

All case components are manufactured from pure aluminium, some of them machined from the solid. Absolutely no ferro-magnetic components are used.

The T+A PA 3100 HV Integrated Amplifier

The T+A PA 3100 HV is a further development of the PA 3000 HV, and most of its sub-assemblies are identical.

The immediately obvious difference is the pair of VU meters in the front panel, which display the power generated per channel in logarithmic form in Watts into 4 Ohms.

A revision of the pre-amplifier section (D.C. coupling) has brought an additional improvement in sound quality.

A further development is the redesigned analogue mains section and voltage power supply, which is similar to that of the A 3000 HV.

This makes it possible to connect the supplementary PS 3000 HV mains section in order to gain a further increase in stability and performance of the power supply system as a whole.

The additional unit provides an extra 1800 Watt of supply power, enabling the system to control even the most difficult loudspeakers without effort, so that they can unfold the best possible sound quality.

As an option the PA 3000 HV and PA 3100 HV can also be fitted with High-End phono pre-amplifier modules which feature different circuit topologies to suit MM or MC systems.

It is also possible to install the analogue signal processor module which has been developed for the P 3000 HV to provide channel-separate tone and loudness functions.

The all-metal F3001 infra-red remote control handset is supplied as standard.

Circuit Topology

T+A Circuit

As with the P 3000 HV, the circuit topology is based on a differential cascode amplifier with individually selected audio J-FET transistors, and stages of completely discrete construction without op-amps (operational amplifiers).

Virtually no overall negative feedback is required due to this circuit arrangement and the quality of the components employed.

The high operating voltage of HV technology is the key to excellent linearity combined with extremely wide dynamic range: signals up to 60 Vss can be processed without distortion.

In the HV series the signal switching and adjusting functions are carried out by encapsulated gas-tight gold-contact relays, which are totally immune to contact problems due to corrosion, dust, etc., and do not suffer from ageing effects even after many years of operation.

The pre-amplifier even employs bi-stable relays, which require no permanent coil current, and this in turn eliminates any adverse inductive effect on the audio signals.

The direct integration of the relays into the circuit minimises the signal paths, and connecting cables – as required for conventional volume potentiometers – are no longer necessary.

The volume control is assembled from discrete precision resistors and gold-contact relays. The result is totally precise channel matching, devoid of distortion and hiss.

T+A

Actually they are scientists….

Ever since 1978 their driving force has been curiosity.

T+A’s aim was to define the framework of the possible, and push its limits a little further each day, and that’s what formed the stone of this company.

They always aspired to the creation of new findings rather than the exploitation of existing knowledge.

They were determined to carve out their own advances, and not simply follow the progress of technology.

Satisfying this goal requires a team of fifteen designers and developers to create every device in their headquarters in Herford.

From the initial design, developing every single circuit board and finishing with the software code – the stage which brings all the component parts together to form a grand ensemble – all devices are built in Herford.

They are permeated by the belief on which this company was founded, and which drives athem forward every day.

They don’t build mass products, they build accoustic treasures, they build heartbeats, goosebumps and enthusiasm.
