Overview

The 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.

About T+A

Ever since 1978 our driving force has been curiosity. Our 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. We always aspired to the creation of new findings rather than the exploitation of existing knowledge. We were determined to carve out our own advances, and not simply follow the progress of technology. Satisfying this goal requires our team of fifteen designers and developers to create every device in our 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 - our devices are built in Herford. They are permeated by the belief on which this company was founded, and which drives all of us forward every day. We don't build mass products, we build accoustic treasures, we build heartbeats, goosebumps and enthusiasm.

Circuit Topology
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.

The T+A PA 3100 HV integrated amplifier is a giant killer. When compared to some of the world’s best audiophile components, very often costing upwards of two or three times as much, this integrated amplifier consistently performs beyond expectations, and has even been described as “virtually indistinguishable” from several of its much more expensive counterparts.

some integrated amps up there, too. T + A’s brand new PA 3100 HV aiming at top honors – and it has a secret weapon in the form of a powerful auxiliary power supply.
Stereo Magazine
The PA 3100 HV, despite its size, is the antithesis of a big bruiser amplifier. More BMW than Porsche, it delivers a refined confident listening experience with excellent weight, poise and speaker-driving ability.
