Overview

In order to take full advantage of the enormous sound quality of the DAC 8 DSD, an extremely good amplifier is required, which is uncompromisingly constructed and equipped. This is why the AMP 8 is based on the circuit and design technology of our HV and R-series amplifiers. The design is fully symmetrical and the output stages are equipped with high-performance ThermalTrakTM audio transistors. A cleverly programmed micro-processor monitors the AMP 8 and controls the protection circuit, which switches of the output relay in case of a short circuit, overheat and overload.

One must not be deceived by the small housing size, the AMP 8 can deliver due to its extremely stable power supply more than 100 watts of continuous output power in the highest quality. The slow-running cooling fan is silent, and is controlled by the micro-processor according to load and temperature. The AMP 8 sounds sensational: vigorous, dynamic, high-resolution yet delicate, subtle and audiophile. The combination of DAC 8 and AMP 8 sets new standards far beyond its price class.

Technology

The overall circuit design of the AMP 8 is that of our sensational PA 3000 HV integrated amplifier, which is why the input stage and the voltage amplifier stage operate at much higher voltage potentials (HV – High Voltage concept). The input stage is a cross-coupled J-FET cascode amplifier, while the voltage amplifier stage is a single-ended Class-A Hawksford FET cascode. The output stage is responsible for current amplification, and is equipped with ThermalTrak TM high-performance audio transistors to ensure that the bias point is totally stable and free of inertia effects. The voltage amplifier stage and the current amplifier stage are completely separate from each other, and each has its own power supply. This prevents any feedback effects from the loudspeakers influencing the voltage amplifiers, which are crucial to sound quality. We call this circuit concept ICA (Isolated Current Amplifier), and developed it years ago for our R-series of equipment. The individual stages are of extremely linear, broad-band design, with the result that the AMP 8 requires very low levels of “overall” negative feedback; the bandwidth is more than 200 kHz. Our engineers have invested tremendous effort in creating a circuit track layout with absolutely minimal inductivity, thereby helping to achieve superb transient and dynamic response.

At those points in the circuit which are crucial to sound quality we employ carefully selected audiophile components such as amagnetic Vishay resistors and special WIMA and ELNA audio capacitors.

The mains power supply is designed to cope with extremely severe and difficult loads. Its torroidal transformer generates up to 400 Watts whilst maintaining low leakage fields, and is capable of driving even very demanding loudspeakers effortlessly. The power supplies for the amplifier stages are completely separate for each channel, and feature their own reservoir capacity and buffering. In consequence there is no trace of interaction of any kind between the channels.

"Dynamic range is one of the most noticeable improvements the AMP 8 has over many of its rivals. The amplifier simply has better dynamics than its rivals...If you buy this amplifier, it’s a decade long commitment to a design that will not age, falter, materially change, or in any other way fall to bits for the next two dozen years at least. To me, that’s a highly attractive prospect, but I know people who change equipment with the seasons and they will find this unbreakable nature challenges their decision making process. Recommended for the long game!"

"…an impeccable bundle of musical fun with a very reasonable price tag. A big thumbs up from me!"

"Voiced perfectly to make a great system when used with the DAC 8 - its natural partner - the AMP 8 sounds crisp and vivid with just the right balance of warmth and civility to avoid it appearing relentlessly analytical. If you can accommodate a bigger pair of floorstanders, the AMP 8 should drive them with ease, making for a high end system without breaking the bank. It´s another outstanding design from T+A."


Do not underestimate this amp! Small size and modest specifications do not tell the story here at all. Those that have heard the T+A AMP 8 will attest to the high level of performance this amp provides. This amp has dynamic snap and drive, yet it does so in a manner that doesn’t come across as being overly analytical at all. It’s a superb match, of course, to the DAC 8 DSD. We’ve successfully driven the ATC SCM40 speakers with this amp which speaks volumes as many don’t recommend less than 200W into 8 ohms and only the highest quality amp with this speaker; yet the AMP 8 provides the drive and control to make the ATC sing. It’s really quite shocking how well this amp performs. We’ve even had a customer say that he felt it came across as more powerful than a highly regarded 125W Simaudio amp and also felt it sounded superior as well. That’s high praise indeed considering its price. For many, this is all the amp you’d ever need and it comes at a relatively affordable price as well.
