A 3000 HV Power Amplifier By T+A HiFi

The A 3000 HV power amplifier is the perfect match for the P 3000 HV pre-amplifier, delivering exceptional performance and extraordinary sound. Designed as a stereo amplifier, it can easily be configured to mono mode with separate amplifiers for the left and right channels, doubling its current output and pure Class-A power for unmatched performance. Utilizing advanced HV technology, this amplifier offers a level of sound quality and power that exceeds much more expensive models from other companies.

By separating the pre-amplifier and power amplifier, T+A’s design allows for the finest circuit and mechanical engineering without space or case limitations. Pre-amplifiers process smaller signals and focus on minimizing interference, while power amplifiers handle larger signals, requiring exceptional power supply stability and current delivery. The A 3000 HV excels in both areas, delivering flawless performance in every situation.

The amplifier’s power circuit, output stages, and mains supply are housed in a dedicated shielded compartment, ensuring minimal interference. The voltage and current amplification stages are housed on separate, isolated circuit boards to prevent interaction, with galvanic separation further eliminating feedback from the speaker currents, ensuring pristine audio fidelity.

The amplifier’s advanced design includes a highly linear, broad-band differential cascode amplifier and a Class A large signal stage for superb sound. The fully symmetrical output stage uses MOSFET drivers and thermal tracking bipolar output transistors, delivering audiophile-quality sound with outstanding current delivery capacity. The power transistors are monitored for temperature, maintaining a consistent operating point to control distortion regardless of load or temperature fluctuations.

T+A has also ensured full symmetry in all components, eliminating magnetic stray fields and electromagnetic feedback to preserve signal purity. The amplifier’s high-quality speaker terminals are machined from solid brass and rhodium-plated for exceptional conductivity, durability, and corrosion resistance, ensuring the best possible connection.

For audiophiles seeking the ultimate performance, the PS 3000 HV supplementary external power supply unit is available to further enhance voltage and current delivery, optimizing the entire audio system.

“I had very high expectations for the T+A P 3100 HV, with thoughts of it for years and years, and it still managed to impress me more than I could have imagined.”

Future Audiophile
“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.”

“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 fist.”
