Very Finest Technologies And Uncompromising Design
The AMP 8
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 mikro-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.
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.
DAC 8 DSD
The DAC 8 DSD
Fundamentally our new DAC 8 DSD is capable of doing everything necessary to convert every form of digital source into analogue signals at the very highest quality, including DSD right up to the highest possible resolution. We have again further improved the unit’s outstanding pre-amplifier, and incorporated a volume control of fully analogue construction based on High-End Melf resistors. The “State of the Art” output stage is of fully symmetrical design and discrete construction. Its impedance is very low, and it is equipped with symmetrical(XLR) and asymmetrical (RCA) outputs. These features make the DAC 8 DSD more than just a High-End converter: it is also a High-End pre-amplifier of supreme quality.
The core of the DAC 8 DSD is the converter. As in our high-end players this device also employs the superior quadruple arrangement with eight 32-bit converters from Burr-Brown in a double symmetrical circuit. This circuit provides perfect compensation for non-linearities, and the residual background noise – which is excellent in any case with the 32-bit converters we employ – is reduced by approximately a further 6 dB. The result is a dynamic performance which is hardly capable of improvement, with a perfect “black level”, extreme linearity and freedom from distortion, even in critical passages and the most minute musical details. Oversampling is carried out by a modern 56-bit signal processor, for which T+A has developed algorithms specific to our equipment, offering perfect timing characteristics. They are based on Bezier polynomials: Bezier interpolation and Bezier / IIR combination. A standard FIR filter and a short FIR filter are also provided. These options make it possible to select the optimum sound quality to suit the individual piece of music. The DAC 8 DSD can even invert the absolute phase of the audio signal at the digital level, and thereby correct material recorded with incorrect absolute phase.
The MP 8
The MP 8 looks small and inconspicuous. At first glance the casual observer may think it is just a classic CD player, but its true capabilities extend far beyond this. Our multi-source player houses a first-class CD mechanism; a high-performance digital tuner offering FM, FM-HD and DAB+ reproduction; a high-quality Bluetooth streaming module for receiving music from mobile devices, a streaming client with Internet radio and music services for connection to the home network via LAN and WLAN, USB Master Mode and HD streaming plus a digital connecting board with inputs for external sources (two USB device mode and three HD-S/P-DIF). The wide range of connections allows external equipment to exploit the machine’s superb signal processing to the full. Please note: the MP 8 is not a computer; it is a high-end audio device incorporating many supplementary functions designed to ensure that all modern digital sources can be used, reproduced and processed to a D/A converter in the highest possible quality.
T+A was one of the first High-End manufacturers to install additional digital sources in its CD players. This was an unusual idea, but can now be seen to be a consistent and logical approach. We call these devices Multi Source Players, and all our High-End series now include them. Our design engineers were asked to integrate five high-quality digital sources in the very small case of the Series 8 range, and this represented a particular challenge to them. The first source is a high-quality CD mechanism boasting very fast access times, and its error correction is outstandingly good. Although the CD has been very largely superseded by streamed content, it is very clear that our customers still harbour the wish to be able to play CDs. We have developed a disc mechanism featuring refined mechanical design and a floating suspension. It just barely finds space in the small cabinett of the MP 8.
