* Push-Pull in AB Class Mode : working in a 2×40 watts push-pull system in AB class, working in triode mode. Based on 4pcs*EL34 power tubes and 2pcs*12AX7 control lamps (ECC83) and 2pcs*12AU7 control lamps (ECC82),the amplifier reproduces a very even sound, without any coloration.
* Good Sound Quality with Tube Warmth Feel: the Yaqin MC13S has a very minimal and straightforward circuit, doesn’t have bells and whistles normally found in more expensive integrated amplifier. The bare-bones circuitry of this amplifier delivers a very high-quality sound. The circutry is based on a time tested , ultra-linear push-pull design which made the sound of an EL34 based integrated amplifier the mainstay of frugal tube amp audiophies.
* High-grade Components：many of the circuit components are of audiophile grade, produced by well-known Japanese,American, and European conpanies, such as Solen/Philips/Siemens/Thomson capacitors, Alps volume controller.High quality STALLOY transformers were used.
* Well-made Quality: well-made chassis is composed of a brushed anodized aluminium front panel in 10mm thickness, two anodized aluminium side panels in 4mm thickness,and top and bottom covers made of high quality steel, the four line inputs , six banana speaker plugs ,the volume control and the input switch are first rate
* More affordable Price ：Yaqin MC-13S can be considered one of the best class A integrated amplifiers, namely the best integrated amplifier under 1000 dollars. With the lack of extra features normally found in more expensive amps, and primary focus on the sound quality that a tube amp is expected to provide, it can fall under a thousand dollars.
YAQIN MC-13S is considered one of the best class A integrated amplifiers in 2021 by review group of amplifier experts in USA and Europe.
The first guarantee to Yaqin MC-13S high-quality sound is the bare-bones and straight circuitry and ultra-linear push-pull design.
The second guarantee is the high quality of components including audiophile-grade resistors, coupling capacitors, and volume controls.
Off all the components, the transformers stand out most. Both the input and output transformers are very high quality. It starts with the oxygen-free enameled copper used in the windings for the transformers cores. It ends with the use of 35-milimeter Japanese steel sheet employed in the building of the laminated stacks surrounding the core windings.
