Opera Audio tube amplifiers

Simple, Human" our philosophy

Like other Hi-End audio manufacturers, Opera Audio specializes in the development and research of tube audio amplifiers and CD-player. The goal of realizing the beauty of music since the establishment of the company 11 years ago has not been changed. "Simple, Human" refers to revealing as much as possible the original spirit and artistic content of music. To fill a static, cold machine with solid cultural content and artistic energy, until the greatest visual and musical satisfaction is reached. 

About the vacuum tubes used by Consonance amps and CD-players

Opera Audio has been manufacturing tube amplifiers for 11 years now. Throughout the 11 years the choice and application of tube has gradually become their own principal and style. Keen followers of Opera Audio will notice that, the power tubes used are mostly EL34/6550, 6L6/KT66 and 300B/2A3. Although the tube brand names has changed from time to time but the type used are still the same. It is the sound delivered by the power tubes that becomes the first principle of Opera Audio's choice of vacuum tubes. EL34/6550, 6L6/KT66 and 300B/2A3 belongs to the high efficiency types with lively and detail sound, good transparency in high frequency.
 
About single-ended amplifiers...

Single-ended class A amplifiers belongs to the elite family of tube amplifiers. Nowadays the famous Hi-End tube audio manufacturers like Jadis, Audio Note, Cary...etc all have their top model based on 300B single-ended amplifiers. The most famous vintage single-ended amplifier belongs to Western Electric's WE 91A, which was used for theatre and public PA application. They began in 1935 using a single 300B (early models were using 300A) with two 6C6 pentode and an input transformer to accept balanced input. Since the 300B has very good linearity, coupled with the simple class A single-ended circuit the harmonic distortion generated at the rated output is relatively small.
