Classic (Beijing Yushang Electronic Audio Technology Co. Ltd.) is a Chinese manufacturer that specializes in development, research and production of high class audio equipment.

For years Classic products have captured the attention of audiophiles domestically and abroad and they have earned a strong market position, becoming one of the leading high-end audio brands in China today.

Before Beijing Yushang Electronic Audio Technology Co. Ltd. was established, in 1994 the Classic brand had already been registered and used. In that time Classic had only one model, a vacuum tube power amplifier, the YP1300B. When launched, the unit gained a broad attention from audio experts domestically and abroad.

Electronic parts used in Classic designs are high quality European, Japanese and made in USA components, they not only sound superior but give a much higher reliability to our amplifier designs.

The vales use in Classic's vacuum state designs are domestically made Shuguang high quality valves, Russian, Czech or made in USA types.

At Classic we have our own research and development division that is working on improving performance, quality and reliability of our products.

Classic amplifiers are made using high quality CNC made aluminum and steel parts, these high quality parts ensure a very rigid amplifier cabinet and a superb and detailed finish.

Classic has given expression to designer’s concept and pursuits technology, art, and esthetics, Classic's ambition is to reach perfection in amplifying design.

All Classic products come with a 12 months limited SSA warranty, unless otherwise specified.

Classic N°6.6 , top class, remote contolled, integrated stereo amplifier:

No.6.6 is a top-grade integrated solid state amplifier that was launched by Beijing Yushang Electronic Audio Co., Ltd in 2001. It's build features nobleness and elegance. With excellent technology, it is the third generation of product derived from Yushang’s patent circuit. After years improvement No.6.6 has gradually attained perfection.

FEATURES:

1. Pre-amplifier sector:
Regulated power supply uses special SEPP circuit, which can keep an ultra-low noise and ultra-low internal impedance. The open-loop frequency response at pre-amplification attains a wide of 330KHz(2V-3db) and wide of 620KHz(2V-3db) at closed loop. Having no lag compensating capacitor and with less harmonic distortion, it's acoustics upgrade to higher level.

2. Power amplifier sector:
The problem of bad common-mode rejection ratio caused by single-end voltage amplification being considered, a dedicated electricity circuit is added to resolve the problem. Penultimate stage driving adopts common-source and common-base circuit configuration, which has the best linearity and also has important action to reduce the distortion-growing problem etc, due to pairs of high power transistors in parallel. Each sound channel has three-group power supply separately feeding to final stage, penultimate stage and voltage amplification stage.

3. Power supply sector:
No.6.6 uses two 450W ring transformers (supply separately to left and right channels) that have, the best quality in China. Pre-amp and remote control use a R-shaped transformer. No.6.6 has around 100000µ electrolytic capacitors for filtering, four groups of electronic filters and two groups of regulated power supply.

4. Full-functioned remote control includes ON/OFF, mute, volume and input selection, etc. Exquisite and exalted remote controller is made of costly aluminum alloy and the design of its buttons especially conforms to the principle of ergonomics.

5. Perfect workmanship and construction:No.6.6 has shortcut and rationalized internal connection, and good electromagnetic compatibility. Its potentiometer is pull-rod mode. Thick copper columns are used to connect part of its circuit boards.

Av interfaces are dedicated 3+2 mode both for AV and Hi-Fi and adopt special earth wires switchover selection switch to ensure using Hi-Fi system against interference from AV system. No.6.6 has better adaptability to different kind of loudspeakers and more comprehensive performance. Its sound representation: full and munificent, clear and elegant, great spatial sensation and accurate acoustic image localization and much better compatibility with every kind of musical and audio form and style.

Classic N°6.10 , high class, remote controlled, integrated stereo amplifier:

No.6.10 is an integrated solid state amplifier. On the design of its circuit, it emphasizes the importance of high sound quality. Although its circuit is mainly designed according to the patent circuit of Beijing Yushang co., It's circuit transmission function has been re-calculated and re-designed. The improved circuit has lower output internal impedance, distortion and better transient response, both keeping the Classic product’s style and expanding music expressive ability.  It's design of appearance highlights succession to culture, which makes it possess more internal relation between its sound quality and looks.  Input selection switch and volume potentiometer are pull-rod mode, so it maximally shortens the length of signal path. Having an earphone jack, it is convenient for users to enjoy music with earphones. The circuit boards adopt large-area ground screen and widens fused stannum at the place from which large current pass. It uses Toshiba high power transistors, Rubycon MUS electrolytic capacitors, ALPS motor potentiometer, which are made in Japan, and WIMA MKC capacitors from Germany. Polystyrene capacitors and metal film resistors are customized by Classic. High power resistors are Japanese KOA foil non-inductive ones. R-shaped 260W transformer is specially designed. A full-function IC protection circuit is installed. The remote control unit includes stand-by, mute and volume.

Specifications:

Output Power: 80W(8ohm RMS)
Output Power:130W(4ohm RMS) 
Frequency Response: 5HZ-110KHz(-3db 8ohm 80W) 
Total Harmonic Distortion: 0.066%(1KHz 80W) 0.066%(10KHz 80W) 
THD+Noise: 97db 
Input Impedance:73Kohm 
Dimensions:490mm(W)×430mm(D)×180mm(H) Net Weight: 10Kg Gross Weight: 12Kg
