Xiamen Baru Vatican Series ESTi-iA80 merger amplifier

World-class quality ESTi-iA80 capture the details of the ultimate place for music, sound with open and smooth, sound, extending the level is quite good, high frequency overtones very distinguished, kind of similar to the single-ended 300B tube amp taste, able to contain detailed in the music and the emotional mood excavated. Unique circuit architecture: J-FET input: Input is the use of the JFET as an input amplifier, the input impedance can take a lot of sources. Bi-Polar / Mos-FET conjugated tube (ESTi independent R & D) output: the transistor amplifier tube triode low frequency is good, but not high-frequency, high-frequency FET and good, but with the same tube, low frequency no. In ESTi-iA80 transistor amplifier, and Dr. Cai Hongren creative way to a transistor and a FET amplifier tubes into one, whichever the advantages of both, to get the full three-band equalizer perfect sound. D- type using feedback mode, no big loop feedback, reduced from the speaker to expand the influence of the machine, to avoid delays feedback exists to improve the situation of transient intermodulation distortion, making more accurate sound performance. Carefully selected components: the whole machine artificial selection, defining parameters, computer precision pairing, 2% accuracy, while 100 pairs of precision tubes can only be used with the six pairs. All elements entirely original product, and some even 20 years collectible items, quality components industry is absolutely first-class, and some are far better than today's very high-priced products. Independent left and right channel output volume adjustment: ESTi-iA80 unique independent left and right channel volume adjustment function, you can for the living room or theater room complex hear sound environment, namely the volume of the left and right channels individually adjusted to meet about two When faced with different channels hear sound environment for speaker output power of different needs. Friendly, rich listening modes: ESTi-iA80 merger amplifier operation, hear the sound mode rich source, volume, forward and reverse other operations via the front panel buttons the machine can also be realized by remote control, and via the front panel The display shows the current operating status of Understanding; automatic memory function (automatically saves the last listening volume when the signal source, forward and reverse etc.) are very friendly. And can independently turn off the display, so that whole sound of the interference to a minimum. ESTi-iA80 belongs to a class AB amplifier and power amplifier bias CPI: ESTi-iA80 belong to class AB amplifier, compatible with Class A and Class B amplifier advantages, but also can be seen as biased Class A amplifier. Each machine from actual test data, with almost no distortion, the actual test each machine large dynamic only even harmonics, in the sense of hearing thick bass, alto supple warm, clear treble neat hierarchy feeling good, very likable. What is the reverse: the phase response, here it refers to the phase when the recording and playback of record albums when, in the album recording, mixing or mixer has an important buttons, is Phase phase, labeled 0 and 180 , meaning that normal and reverse, that normal and reverse what is it? That is when the sound wave included, is positive or anti row before the first row. Wiring is not uniform, CD players and other audio output phase is not uniform, before and after class and other output phase is the cause of disunity are reversed. Reverse performance: stereotactic recordings will sound when inverted, and counterproductive, for example, included a violin solo during recording, the sound of the violin would highly stereotactic about the height of a person, if the live recording of the stage, because there stage relationship, height may be higher, and that the correct phase when only two speakers in the middle of this recording will reproduce three-dimensional positioning, the easiest is to have a high degree of relatively deep, but how when equipment inverted? No sound is played back height no depth, only sound in the ground, which is engaged in anti-phase sound. ESTi-iA80 built-in phase inversion function, you can hear the sound process, phase reverse switch at any time! ESTi-iA80 performance of sound: ESTi-iA80 capture details of music is in place, sweet voice is beautiful, with open and smooth tone, timbre, extending the level is quite good, high-frequency harmonics are quite outstanding, kind of similar to the single end of 300B tube amp taste, able to contain detailed in the music and the emotional mood excavated. Pictures of their dynamics and control performance is very good scene, sound dynamic changed greatly, from low to high, undulating music full of tension, elasticity and rich flavor; for orchestral performance, the whole wide vivid sense of space, both easy and real instrument sounds clear and explicit part of the cloth, strength, density, rhythm stunning, the level is very rich! ESTi-iA80 not only showed undulating melody symphony, but also showed a band instrument lines and texture, dynamic stretching and low frequency bombardment force is always a superficial. -iA80 is a beautiful sound good at performance and exquisite musical content of the amplifier
