O Class-A parallel push-pull output stage 0 Low-impedance load drive capability 0 Full twin mono construction. The balanced signal transmission used in the P offers a perfect solution which ensures that the voltage potential in the ground line is zero at all times. This effectively prevents any kind of external interference.
The output devices of the amplifier operate always in the linear range, thanks to the class-A drive principle. Crossover distortion is completely eliminated, and the current supply is always kept constant, which has the same effect as using a power supply with infinite capacity. The design of the P stands in the same tradition as the top-of-the-Iine P- , with large, wide level meters behind a thick glass panel and all controls and functions arranged behind a subpanel, This gives the amplifier an appear-.
By using the P in combination with the preamplifier , an entire system with fully balanced signal transmission can be created, which offers the ultimate in reproduction quality. The sound quality potential of truly accurate program sources can now be fully appreciated in the home, for unlimited musical enioyment. For the transmission of Signals in an audio sys- tem, two basic patterns are available: the unbal- anced principle as shown in Fig.
Unbalanced circuits are widely used in home-use compo- nents, as they are simple and easy to design, In this type of circuit. An inherent advantage of this principle is that it can cancels out not only noise induced during the transmis- sion process but also distortion components arising Within the amplifier. This cancellation takes place in the output circuits. The P features balanced signal transmission through- out. The circuit configuration of the PTO? The top and bottom half are made up by two exactly identical amplifiers arranged in par- allel.
Another distinguished feature of the P is its use of classA operation. This principle is ap- plied not only to the input circuits. As can be seen from Fig. This enormous power capacity is called upon to supply only one half of the 50 watts of rated output power, Le, 25 watts. Effortless speaker drive even under the most demanding conditions is the result of this approach.
The design also ensures that the amplifier will remain stable even with very low impedance loads, delivering a maximum output of 70 watts per channel into 2-ohm loads. To achieve this performance. It must possess low output impedance and supply a high swing voltage to the output stage This requires the use of high» quality power-amplifying elements which can withstand high voltages.
To achieve this aim, Accuphase uses a class-A cascode push»puli differential circuit configuration in the input stage of all its power amplifiers. As the circuit diagram shows, the transistors Qla and 05, 02a and Q1 b and Q13, 02b and OM in the upper amplifier block are connected i a cascade bootstrap configuration the I block employs the same principle.
The cascade-connection principle was original» ly developed for radio»frequency amplification. It ensures stable operation over a wide range, resulting in outstanding input linearity and wide dynamic range,. With class-A amplifiers, the power provtded by the power supply is almost constant except for designs which modulate the bias voltage of the output stage , and there is usually little interfer- ence between the two stereo channels. To pre vent even the slightest possibility of interfer- ence.

Model Retail price in in Germany: Black 1. There is not much Rowland here but you have to admit that even if it is completely ICE technology, it is still the prettiest application so far, plus it is very reasonably priced! The model sounds very good: neutral, fast, transparent and refined, and it is much more powerful than its diminutive size seems to indicate, driving Magnepan MG3. Ultimately tonally a little on the dull side but still extreme value for money. Model together with the same-sized Capri. To me, the is the star of the couple.

Accuphase Stereo Power Amplifier Problems
The P inherits technology features and concepts of the 40th anniversary commemorative model A and subsequent M and takes these even further. Some of the highlights are a drastic reduction in noise and a significant further improvement of the damping factor. In the final stage, the parallel configuration of output devices ensures high current capacity and keeps the output impedance of the power amplifier extremely low. This further improves the ability to handle any speaker with competence, realizing constant-voltage drive even with extremely low load impedances. The guaranteed damping factor of at least 1, demonstrates the impressive success of this approach. By further refining the parallel drive and gain allocation of the input stage, Accuphase engineers were able to push the noise floor to previously unthinkable levels, achieving an amazing signal-to-noise ratio of dB at maximum gain and dB at the —12 dB gain setting.

D ust hasn't settled yet after a review of Vitus extremely expensive though not the most expensive SP phonostage , and I am already presented with opportunity to review two other products from same line: SL stereo linestage and power amplifier SS It's not the first device of this type — let me remind you my review of Leben CSP. In my opinion a popular distinction between power amp with volume control and integrated power amp is more of a customary, it depends on what functionality would be recognized as primary. Of course some might claim that integrated amps have a higher input sensitivity, which makes it easier to drive them for low output signal sources, also that its input impedance can be lower as there is a buffer in the input stage, but if we check facts there are many integrated amplifiers with low input sensitivity, and there are many power amps with a high one.
