T+A

Valve based amplifier V 10

T+A has been in existence for 25 years, and we have been building amplifiers and valve output stages since 1984 - so we can certainly claim to have plenty of experience in this field. To celebrate our anniversary year we have decided to develop a unique range of superb new products, and introduce a new High-End series for audiophile fans of classic two-channel reproduction.
Naturally our aim in developing the V 10 was - once again - to set entirely new standards. This integrated amplifier features a range of technologies which have never been seen before in valve-based amplifiers.

Power, Quality & Stability:

High output power is a fundamental necessity in our view, but not at the cost of hideous case designs and Utopian expense. We found the solution to this conundrum in new valve types which have never been used before, in combination with an ingenious circuit design which we have termed SPPP (Single Primary Push Pull). This eliminates the symmetry problems in the output transducers [Uebertrager] of conventional valve amplifiers.
A crucially important factor to our developers was the stability of the amplifier's sound qualities and technical performance in practical daily usage. The problem here is the valves themselves: on the one hand individual examples from normal production vary enormously, and on the other the valves are very sensitive in operation and suffer inevitable ageing effects. To overcome these problems we have again introduced measures which we believe to be unique: all valves are subjected to a sophisticated selection process, and only the units exhibiting the closest tolerances are approved for use in our amplifiers. At the same time a micro-processor constantly monitors all the system's operational parameters, such as signal levels, currents and overload margins. All the device's activities are recorded by a form of dynamic counter, and this information is used to calculate the residual run-time of the valves, so that the valves can be replaced in good time in order to maintain the amplifier's sound quality. The normal useful life of the valve set is in the range 3000 to 5000 hours, depending on load and stress levels. For example, a cold start shortens the valves' lives more than switching on after the pre-warming phase. Idle current levels can be displayed at any time.

Mechanical system:

The mechanical construction and case design of an amplifier of this type must fulfill the most exacting requirements. Any hint of mechanical jolting or vibration has a significant adverse effect on sound quality. For this reason the basic cradle is of strong steel construction, mounted on four shock absorbers. The external aluminum components are of sandwich construction since this provides better damping of body sound, while the thick acrylic panel suppresses and absorbs vibration and prevents microphone effects. The transducers [Uebertrager], the main transformer and the output stage capacitors are encapsulated in solid aluminum containers [Toepfe] which prevent resonance effects and effectively disperse generated heat.

Valve Pre-amplifier P 10

The P 10 valve pre-amplifier is the latest unit in our series of High-End two-channel analogue equipment. Its no-compromise construction and the equally uncompromising sophistication of its circuit design elevate this pre-amplifier to the very highest level. Even from the outside, the arrangement of the valves clearly indicates the amplifier’s symmetrical double mono layout. The signal paths are absolutely identical, as is the sound quality. The interior of the machine (see below) confirms this beyond all doubt.

Circuit concept:

 The P 10’s five valves per channel represents an extraordinary level of complexity. Why such complication? The answer is simple: we were not prepared to accept the quality of sound which was available in the 1950’s. Modern high-resolution source devices, with their unprecedented bandwidth, dynamic characteristics and minimal harmonic distortion, are far more demanding than their predecessors. If we insist on maintaining the very highest standards in terms of sound quality and musicality, and if the pre-amplifier is not to become the limiting factor in the reproduction chain as far as sound quality is concerned, then simplistic electronic concepts cannot be used.
All the amplifying stages of the P 10 take the form of differential cascade amplifiers. This circuit design is responsible for the machine’s extremely broad frequency bandwidth and excellent linearity. The valves in the amplifying stages are the „LPS“ version (Long Plate / Spiral Filament) of the 12AX7, which offers particularly low distortion. The potential sound quality of these valves has already been proved in the D10 and the front end of the V10. In fact, the linearity and quality of the P 10’s amplification stages are so high that we decided against including any form of negative feedback. Even though the classic negative feedback is entirely absent, the P 10’s total harmonic distortion and frequency linearity values are excellent.
The output stage is of fully symmetrical construction, and features both asymmetrical (Cinch) and balanced (XLR) signals. The excellent ECC99 high-current triode valve has proved its worth in the D10, and we decided to use the same component as it enables us to achieve outstandingly low output impedances. The result is that it can drive active loudspeakers or power amplifiers without any problem, even with long cables

All-pole input section:

When the inputs are switched on the P 10, „all poles“ are switched - i.e. the earth connection of the source device is switched in addition to the signal conductor. This is very complex to implement, but ensures that all unused source devices are galvanically isolated from the P 10.
At any one time only a single device - the one currently selected for listening - is connected to the amplifier. In conventional Hi-Fi systems earth currents are free to wander around between the individual components, and these can have a significant adverse effect on sound quality. The problem is solved completely by the all-pole input selection of the T+A P 10.
As with the V10, the input switch is based on an extremely solid mechanical rotary angle encoder featuring a zero-wear opto-electronic sensor. This control, with its slop-free operation and accurate magnetic detents gives a feeling of incredible solidity and precision.

CD - SACD - Player D 10

The D10 is the most unusual SACD player available anywhere in the world; it is an absolute High-End machine, from the case to the valve output stage. The results in terms of sound quality are incredible, and at least equal to the vinyl disc. The D10 is based on a number of components found in the SACD 1245 R, including the disc mechanism, the decoder and the digital section of the quadruple D/A converter. However, the two mains power supply sections of the D10 are much more powerful. For the digital components we employ a secondary switching mains section, with a torroidal transformer which offers excellent stability under load; for the analogue valve output stage we have developed an extremely stable high-voltage mains section which features a reservoir capacity corresponding to more than 100,000 µF with a conventional pre-amplifier.

Quadruple - D/A - converter:

The new converter is unique even by the standards of T+A. The D10 is fitted with no fewer than eight Burr Brown D/A converters - acknowledged as the best of all types. The quadruple converter is a development of the differential converter, reducing uncorrelated converter errors to one quarter, and background noise by 6 dB. The effort invested in this converter layout is immense, but the results are worth it!
As you would expect, a freely programmable signal processor is employed, which means that the machine provides the characteristic T+A switchable oversampling algorithms for CD playback, enabling the user to select the optimum reproduction to suit any particular disc. Our engineers have also developed four-stage oversampling and noise-shaper circuits for SACD playback, which generate different filter gradients and secondary wave suppression, providing a highly effective means of fine-tuning the sound characteristics to match the other links in the equipment chain. The converter stage is followed by an ingenious valve-based output stage. To prevent any danger of the digital section influencing the analogue circuit, these two sections are separated and de-coupled using a unique T+A technique. Opto-couplers transfer the control signals optically, while the latest magnetic, jitter-free iCouplers from Analog Devices are employed for the high-speed data signals. The net result is genuine High-End analogue sound quality both with CD / DVD as well as SACD.

Valve output stage:

The really striking aspect of the D10 is the section which follows the converters: its analogue valve-based output and filter stage. The pre-amplifier consists of the extremely linear, low-distortion 12AX7 LPS double triode, while the output stage features the ECC 99 double triode, with its high current delivery capacity.
All the amplification and filtering is carried out by these valves. This concept is totally unique, and ensures that all the machine’s sound characteristics are determined by the valves - they are not just there for show! With the ECC 99 we have also succeeded in keeping the output resistance to below 100 Ohm. This is a sensational value for a valve pre-amplifier, and we think it must be a record! The DSD process used for SACD inevitably generates increased background noise in the region above about 40 kHz, and not all amplifiers can cope with this. In the simplest case the amplifier simply becomes very warm, but in many cases the amplifier also generates intermodulation effects or other distortion products, and these can have an adverse and extremely disturbing effect in the audible frequency range. One solution for us would have been to limit the frequency response of the player to the lowest common denominator, in order to cope with amplifiers of moderate quality, and this would certainly have been the safe route. However, we were not content with this, so we decided to equip the D10’s valve output stage with a means of switching the bandwidth between 60 kHz and 120 kHz. By this means it is possible to set up the player to match any amplifier very accurately, and there is no need to forfeit anything in terms of frequency response and phase linearity where a good, wide-bandwidth amplifier is used. Naturally all T+A amplifiers are an excellent match for the machine.

Mechanical system:

The mechanical construction of the machine maintains the same philosophy and superb quality as the other V-series components. The combination of solid aluminum and special high-quality acrylic is visually extremely pleasing, and gives superb results in audio terms.
The high mass of the metal and the damping effect of the acrylic ensure that the top-loader disc mechanism is totally de-coupled and isolated from the outside world. The components of the top-loader are machined and turned from solid blocks of aluminum.
The complex cover sealing ring is turned from a single piece of metal, and bonded permanently to the acrylic plate. This design provides outstanding damping and absolute freedom from resonance effects, as well as sealing the disc hermetically from the environment.

Analog Pre-Amplifier - PULSAR P 1230 R

The P 1230 R is a great secret known to all. The P 1230 R supplies simply outstanding sound and superb measured results, and this is due to the overall design and construction of the unit. The sonic qualities and technical characteristics are optimized by the use of double-sided conductor boards with Powerplan, close-tolerance components (FKP capacitors, high-quality op-amps, metal film resistors, and much more). The signal paths are kept short, and even at the input selector switch they are optimized in such a way that conductor inductivity, capacitance and overload margins are pushed to the very limit of what is measurable. Gas-tight gold-contact relays are employed to switch the source devices, in order to ensure freedom from harmonic distortion and background noise.

Power Amplifier - PULSAR A 1230 R

Regarded from a purely external point of view this brand-new high-performance power amplifier gives a slim and delicate impression. Don’t be deceived! Inside the case is a true Goliath: our development engineers have squeezed into it the same outstanding output stage philosophy and circuit technology as the famed A 1530. At the same time the new unit retains all its predecessor’s wonderful broad-band character and speed. You’ll be bowled over by its dynamic reserves, too: the A 1230 can supply more than 500 watts of power for brief periods. The A 1230 looks small, but sounds gigantic.
The new ICA technology, recently developed by T+A, de-couples the amplifier’s input stage from the current pre-amplifier stage. The new push-pull class A mirror current stage is designed to cope with high-level signal processing, and features transistors with a transient frequency of more than 300 MHz. The result is virtually bottomless dynamic reserves, a vast bandwidth and tremendous speed. Naturally the A 1230 R can be used as a normal stereo power amplifier, but it can also be employed in other modes, e.g. for bi-wiring or bi-amping in conjunction with other T+A power amplifiers. To protect the amplifier and the speakers connected to it an electronic circuit monitors the signals in the amplifier. This protective circuit is not located in the signal path, so it has absolutely no influence of any kind on the sound image. The circuit monitors the input signal before the output stage, and compares it with the output signal. If the slightest deviation occurs (clipping, distortion etc.) the circuit switches off the output relays. The protective circuit also trips if the outputs are shorted, or if the unit overheats.

Power Amplifier - PULSAR A 1530 R

Is there such a thing as a powerhouse with tender feelings? Undoubtedly there is, and the new A 1530 is the proof. Its predecessor, the A 1520, was due for a work-out in the gym, and when it emerged it had developed new High End mica capacitors, precision resistors and optimized torroidal transformers. However, the really significant feature of the A 1530 is its silver / copper circuit board technology, which is completely new in the audio world. This innovation has also been introduced in all our power amplifiers and integrated amplifiers, with immediate effect. The new technology, developed in the field of RF applications, uses silver as the conductor in the circuit boards, and the sonic advantages are enormous. The new circuit boards are also non-magnetic, and all connections and contacts are also non-magnetic, completely eliminating the disturbing distortion which can be caused by induction effects.
The ICA technology incorporated in our amplifiers was developed by T+A with the aim of de-coupling the amplifier’s input stage from the current amplifier stage. The result has been a clear improvement in the overall sound and in the spatial characteristics. The new push-pull class A mirror current stage is designed to cope with high-level signal processing, and features transistors with a transient frequency of more than 300 MHz. The result is virtually bottomless dynamic reserves, a vast bandwidth and tremendous speed. Naturally the A 1520 R can be used as a normal stereo power amplifier, but it can also be employed in other modes, e.g. for bi-wiring, or bi-amping in conjunction with other T+A power amplifiers.

Integrated Amplifier - PULSAR PA 1530 R

Almost no other range of products reflects more clearly the success of T+A than the class of the large integrated amplifier. The PA 1520 R was far ahead of its time and has proved it over many successful years, and now the PA 1530 R is ready to re-define those same standards. The re-designed circuitry and unique silver/copper circuit board technology make this unit even more powerful and capable, both in terms of measured and perceived performance. Many components in all the signal paths and the output stage have been superseded by even more capable High End parts, producing further clear improvements in technical and sound terms. The PA 1530 R now represents our most highly developed and refined powerhouse. It represents the technical standards of tomorrow, and with its unbridled dynamics it sounds unashamedly good.

CD-Player - PULSAR CD 1240 R

The CD 1240 R offers even more sophisticated features than the CD 1230 R. The bass range is assigned to multi-bit converters for their outstanding sonic qualities, whilst the treble range is assigned to superior Sigma/Delta converters, now boasting 384 kHz / 24-bit resolution. It is also equipped with a freely programmable signal processor (DSP) which provides the basis for five different switchable oversampling filters (see CD 1230 R). As standard it features one additional high-quality digital co-ax output, sophisticated mains power supplies with separate high-performance transformers for the digital and analogue sections, and additional copper shielding. It is difficult to believe, but the CD 1240 R sounds even better than its renowned predecessor, the CD 1220 R.
2-way-converter: Multi-bit and Sigma/Delta (1-bit) converters each have their own advantages in terms of sound quality. Whereas the multi-bit converter provides outstandingly impressive and well-rounded sound characteristics, especially in the bass range, Sigma/Delta converters offer unexcelled clarity, fine detail and resolution in the high-frequency range. The CD 1240 R combines the advantages of both types of converter.
In fact the CD 1240 R features no fewer than three converters on each channel: two Sigma/Delta converters in double-differential mode and an additional 20-bit multi-bit co-linear converter. The multibit DAC is responsible for the conversion process in the bass range, while the primary use of the Sigma/Delta types is in the mid-range / treble area. The net result of these innovations is improved sound plus significant reductions in residual background noise and harmonic distortion compared to products exploiting the previous state of technology.

CD-Player - PULSAR CD 1230 R

The sparkling new little brother to the CD 1240 R has everything that its sibling offers apart from the two-way converter, the co-ax output and the dual-transformer mains section. This gives us the chance to mention a few of this family’s exemplary qualities: Two Sigma-Delta stereo converters operating in double differential mode for optimum performance in terms of noise, overload and dynamics; T + A reverse clock process provides 192 kHz / 24-bit resolution and eliminates jitter, driving the performance of the system close to the physical limits.
As with our other CD players this unit employs a freely programmable signal processor (DSP). DSPs are not limited in the way they can process digital signals, and for this reason such a system ensures better oversampling than would be possible with standard conventional chips. Until now oversampling filters were designed to provide as smooth a frequency response as possible, but their timing characteristics (pre- and post-echo) have been neglected. The problem is long pre- and post-echo effects which can seriously distort the musical signal, especially with transients. A different type of filter is now available which exhibits perfect transient handling: these are known as polynomial filters, and unfortunately they are characterized by a slight treble fall-off at 20 kHz. In the CD 1230 R we employ a particular class of these filters which has been developed by T+A: BEZIER polynomial types. These are combined with an IIR filter in a three-stage oversampling process. The result is a filter which produces no pre-echoes. The human ear is particularly sensitive to pre-echoes for two reasons: on the one hand such an echo can never occur in the natural world, and on the other they are not concealed by the main signal, unlike post-echoes. This new filter also boasts a frequency response which is considerably smoother than that of other polynomial filters (e.g. cubic spline types). Such sophisticated filters cannot be purchased ready-made, and that is why a digital signal processor is employed in the CD 1230 R. The freely programmable signal processor of the CD 1230 R is not tied to a single filter, and this makes it possible for the unit to provide five different filter types offering subtly different sound characteristics - from the classical long FIR filter via short FIR filters to the BEZIER filter. These filters can be selected by means of a button on the front panel of the unit.
