Mô tả sản phẩm: Chord SPM 1200 MkII
A Hi-Fi World magazine 5-globe winner the new SPM1200 MkII has been described by Britain"s biggest hi-fi magazine as: "A winning combination of power with precision...the SPM1200MkII is an absolute delight. Very highly recommended." (You can download the PDF review on this very page.) Much of what Chord has achieved is the result of using innovative, leading edge technology. For example, we believe that we are unique in using the technique of 'dynamic coupling' of the power supply rails. Whatever transient demand is presented to the amplifier stages, the positive and negative rails remain in perfect equilibrium, with each compensating for the demands made on the other. This means that power delivery is always balanced and free from ground loop modulation distortion.
This, combined with enormous reserves of instantly delivered, precisely controlled power is what makes the SPM 1200MkII sound so effortless. The power supply rails operate nominally at ± 90 volts, well above that which most amplifiers can accommodate. This and other advanced techniques enables the ultra high frequency low ESR power supply to store a great deal more energy far more efficiently. Clipping is virtually impossible. Furthermore, compared to other amplifiers of a similar power rating the SPM 1200MkII weighs in at a mere 18Kg. Another new technique is used to protect the amplifier against overload, internal and external short circuits. The output signal path is totally free of any fuses or sound-degrading resistive components often employed for overload sensing. The SPM 1200MkII is designed to surpass the highest European safety and electromagnetic interference standards.
The amplifier sections are also highly sophisticated designs that make the most of the best high voltage, lateral structure MOSFETs available, 16 x 150 watt devices per channel. Combining the subtlety and musicality of a good valve design with the punch and accuracy of 'state of the art' solid state products. The result is a 'sliding bias' class A/B design with all drive circuitry operating in class A. At usual listening levels, most of the music will be reproduced in class A. Chord's no-compromise design philosophy means there is no better built amplifier. Individually hand-crafted, it is constructed to aerospace standards from the circuit boards up.
