3、eld. It is based on the circuit designs used in the highly successful EAR 834P phono stage and 834L line preamp, with a few additional refinements and features including balanced outputs and one balanced input, all coupled via high quality transformers. It has facilities for one phono input (MM/MC)
4、and five line inputs, and offers a genuine tape monitoring circuit, making a total of seven inputs. A high quality volume control is fitted, as well as a panel mounted power switch. Input and output terminals are gold plated. The EAR 864 is the perfect match for any high end system, whether biased t
5、owards analogue or digital. The electronic architecture is minimalist, so that the absolute minimum sonic degradation takes place. There are five double triode valves, arranged in a classic de Paravicini circuit. Special attention has been made to the input circuitry. All inputs are at the rear of t
6、he chassis, on the same circuit board as the selector switches, which are operated remotely by long control shafts. Power supply is a unique arrangement; a high quality toridal transformer feeds a double DC power supply, that provides the low-tension (LT) heater current, and the high-tension (HT) an
7、ode voltage. It is critical in a preamplifier that both the HT and LT supplies are pure DC, and free from AC ripple. This is the case with all EAR products, not just this preamplifier. The circuit is designed in such a way to have a minimum life of five years continuous operation for the valves (bar
8、ring random valve failure). The pre amplifier has more than enough output for any power amplifier, transistor or valve, and is ideal for driving long interconnect cables to remotely located power amplifiers.Magazine ReviewsSPECIFICATIONSInputs 1 x phono5 x line level unbalanced (RCA phono connector)

10、ist 1 x ECC 82, 4 x ECC83 After years of research, development and day-to-day manufacture with the EL519 series of pentode tubes, Tim de Paravicini has come up with a new and exciting Triode configuration. Conventional triode connected pentodes have the second grid tied to the anode, which results i
11、n a halfway compromise between a pentode and a triode. This neither has the efficiency of the pentode, nor the linearity of the triode. Tim de Paravicinis Enhanced Triode Mode (ETM) goes one step further, and creates a true, highly linear triode from a robust pentode tube. Instead of driving the nor
12、mal Grid One with signal, this is tied down to the cathode, and thus becomes an invisible, transparent element, and part of the cathode. Signal is fed into the tubes Grid Two, and in this configuration, Grid Three has no effect - it can either be connected to earth, or left floating. The ETM behaves
13、 like a true triode and is in fact more linear than the majority of directly heated triodes. Compared with the latter, it has the additional advantage of being a tough, more robust tube, capable of much longer operational life. The first amplifier to use the ETM configuration was the 859, and with s
14、ome justification the 861 could be regarded as a push-pull version of the 859. However, this is more than a slight understatement: each output transformer has a massive 5 kilogram weight, with no feedback applied around it. The circuit is balanced push-pull from input to output, allowing balanced (p
15、rofessional-style) inputs as well as conventional unbalanced (RCA phono jack socket). Similar to the 859, the circuit is direct-coupled. Tube choice is not critical; perfect operation does not rely on matched tubes, nor on user adjustable bias. Output power is 32 watts per channel, 20 Hz - 20,000 Hz
16、. The half power bandwidth is in excess of 16 Hz - 60,000 Hz, both with low total distortion, and no overall feedback. Tube complement: 2 x ECC83, 6 x PCC88 and 4 x EL519. Amplifier weight: 27 kilograms. Subjectively the amplifier has the same family sound as the EAR 859. Listeners will find it buil
17、ds heavily upon this, with an increase in authority and attack. The lower bass has real grip and feel with this amplifier, way in excess of the 32 watt power rating while the treble is smoother, cleaner and sweeter, mainly due to the lack of overall feedback. A single word can sum up the 861: effort
18、less. It has real power and control, the power to convey the emotion of the most demanding of recordings, whether the source be our preferred analogue or digital.世界著名功率放大器 2006-07-17 19:37北美地区: Bryston(拜事通) 加拿大最具代表的晶体管放大器,产品寿命长,声音理性,力道足Sonic Frontiers 加拿大 Hi-End 胆机代表作,音色细致高贵,力道充沛Classe Audio(驾势) 加拿大
