The A 3000 HV is the ideal power amplifier and complement to the P 3000 HV pre-amplifier. It is designed as a stereo power amplifier, but can also be configured to work in mono mode, in which guise it is capable of delivering twice the current and in which it doubles the pure Class-A mode.

The Power Amplifier
The A 3000 HV is the ideal power amplifier and complement to the P 3000 HV pre-amplifier. It is designed as a stereo power amplifier, but can also be configured to work in mono mode, in which guise it is capable of delivering twice the current and in which it doubles the pure Class-A mode. Thanks to HV technology, this powerhouse offers superb sound characteristics as well as incredible power and performance: a standard which is unsurpassed even by much more expensive amplifiers. The principle of splitting a High-End system into separate pre-amplifier and power amplifier gave our development team the opportunity to implement the finest possible circuit designs and technologies without having to take into account space considerations and case restrictions. This applies both to the electronic components and the mechanical design of the case, since - if the aim is to attain the best possible sound - a preamplifier’s requirements are fundamentally different from those of an power amplifier: preamplifiers process relatively small signals, and the crucial aspect of their design is the avoidance of induced and other interference; power amplifier, on the other hand, have to cope with relatively large signals, and the stability of the power supply, its current delivery capacity and performance independent of load are much more important.

Case Compartment
The entire electronic power circuit with output stages and mains power supply is housed in its own shielded compartment in the underside of the machine. The dividing wall between top and bottom sections is 10 mm thick and - of course - is also made of aluminium. Voltage amplification and current amplification circuitry is housed on separate circuit boards in separate case sections, in order to prevent mutual interaction. The sophistication of the design does not stop there, as we have even provided galvanic separation between the two. Thanks to this uncompromising design philosophy there is absolutely no feedback of the loudspeaker currents into the voltage amplifier stages, and complete freedom from loudspeaker loading effects.

Amplifier Section
The voltage amplifier is an extremely linear, broad-band, cross-coupled differential cascode amplifier, followed by a single-ended Class A large signal stage which provides superb sound quality.
The fully symmetrical current amplifier stage (output stage) is fitted with MOSFET drivers and the latest “thermal tracking” bi-polar output transistors; this combination delivers a very harmonious audiophile sound image combined with tremendous current delivery capacity. The output stage transistors feature integral temperature monitor diodes which we use to maintain the power transistors at an absolutely constant operating point, regardless of temperature, allowing us to control the circuit’s distortion behaviour perfectly, regardless of the momentary load. By maintaining full symmetry in the arrangement of all conductors in the output stages, speaker cables and mains power supply we have succeeded in providing complete compensation for all signal currents. The net result is a complete lack of magnetic stray fields, and no electromagnetic feedback into the input stages.

Speaker Terminals
The enormous power of the power amplifier calls for particularly high-quality, stable loudspeaker terminals; they are machined from solid pure brass and rhodium-plated on every surface. Rhodium is the perfect contact material: as conductive as silver, as durable as platinum, as corrosion-resistant as gold (and unfortunately as expensive as all three put together).
For the most exacting requirements a further option exists for improving the quality of the voltage and current supply: this is the PS 3000 HV supplementary mains unit.

"T+A’s ‘no compromise’ HV series components are designed for the luxury audiophile market. In that context, this latest amp combo is sensational value. We’ve said this so often of T+A’s separates there’s a danger of it becoming tedious: if they were made by a boutique audio manufacturer they’d come with price tags two or even three times larger. Little wonder the German company is selling them hand over fi st." - John Bamford

"If you consider the whole audiophile picture of performance and value, T+A, with its considerable engineering acumen, has produced something exceptional with this amplifier. It is uniquely positioned at this price point in the audio pantheon. This amp simply delivers—and does so by creating a very engaging sonic picture through its clarity, accuracy, dynamics, and bass performance. So much so that I have made the A 3000 HV amp and the matching P3100 HV stereo preamp my new reference electronics, a choice that I expect will bring me years of musical satisfaction. " - Paul Wilson

" Historia serii HV zaczęła się od wzmacniacza zintegrowanego PA3000HV oraz odtwarzacza sieciowego MP3000V, które testowaliśmy w „Audio”. Teraz przyszła pora na amplifikację z samego szczytu – dzielony wzmacniacz P3000HV + A3000HV"

"Der sanfte Druck der Haut, das Streicheln und die Leichtigkeit, mit der sich die Stahlborsten zitternd wieder abheben, das erschien mit der T+A Kette geradezu erschreckend, rückenschauerhaft lebensecht.
So hat der PDP 3000 HV, P 3000 HV und der A 3000 HV die Krone der Halbleiter-Highend-Schöpfung verdient."

"Unglaublich faszinierend klingender Endverstärker der absoluten Top Liga. Enorme Leistung und Stabilität mit gleichzeitig luftigem wie voluminös-souveränem Klangbild. Wunderbar. Topreferenz.
Mit dem Extra-Netzteil nimmt die Kontrolle im Klangbild nochmals zu. Der Bass wirkt nun staubtrocken, wie in einen Schraubstock gespannt. Das gesamte Klangbild wird moderner, kontrollierter und straffer.."

"If you seek real muscle to drive a high-end stereo system, look no further than this premium T+A combo. Both preamp and dual-mono power amp (2x300W/8ohm) hail from its HV (High Voltage) series, where transistor stages are driven at the high voltages normally associated with valve amps, achieving low distortion regardless of power output. Presenting music with a vice-like grip, this luxury pairing conjures up holographic images and reveals fine details with consummate ease. Want even greater power? Then check out the PS 3000 HV power supply upgrade."

"Die T+A-Komponenten spielen so geschlossen, wie man es von solch immensen Bauteilvorkommen nicht erwartet. Auffällig ist allerdings die Geschmeidigkeit und Luftigkeit des Hochtons, den ich in dieser Qualität bisher nur bei Verstärkern erleben durfte, die keine derart exemplarische Kontrolle im Bass bieten konnten.
Apropos Investitionen: Die drei HV-Komponenten von T+A haben meine Maßstäbe verschoben. Sie haben etwas geschafft, was anderen, auch teureren Kollegen vor Ihnen nicht gelang."

"Schwergewichtige, traumhaft verarbeitete Stereo-Endstufe, die hinsichtlich Leistungsfähigkeit und Stabilität Maßstäbe setzt. Feinzeichnend im Klang, verfügt sie über unendliche Dynamikreserven. Mit dem Zusatznetzteil PS 3000 HV legt sie noch zu.
Fazit: Mit der P 3000 HV / A 3000 HV hat sich T+A ein eigenes Denkmal gesetzt. In 30 Jahren wird man sagen: "Das war die ultimative Vor-/Endkombi"
