★ESOTERIC(에소테릭)★ A-02 파워앰프

특징

Abundant use of high-grade components pursued for both their properties and audibility

Securing signal clarity and minimizing transmission loss maximizes pure amplifier performance. Rigorously selected components are used to satisfy to the greatest extent possible such requirements for power amplifiers. Highly reliable XLR input terminals that boast contact performance and Esoteric's original RCA input terminals are just some of those implementations. WBT nextgen WBT-0710Cu speaker terminals are also employed. These conductor cores utilize pure copper with gold plating to achieve high conductivity and low resistance. Moreover, the A-02 employs high-grade components such as electrolytic capacitors and transistors with excellent high frequency characteristics achieved through property examination and repeated trial listening.
 

Ingenious chassis structure that intricately fuses precision and vibration suppression

Internal circuit components are separated into dedicated inner compartments for each circuit, partitioned by 2 mm steel walls. The bottom chassis utilizes 5 mm thick steel for additional isolation that prevents interference between circuits and minimizes the adverse effects of resonance caused by internal and external vibration. The extremely robust inner chassis is composed of a 20 mm thick aluminum front panel and 5 mm thick top. It is also supported at four points on Esoteric-original pinpoint feet. These and other measures help to keep the housing highly rigid and resonance-free. What's more, an approx. 41.5 kg weight (91.5 lbs.) speaks volumes for the rigidity of the A-02.
 

Tranquil yet strong expression in a design that evokes rich musical qualities

A design idea that shows off high-end aspirations through and through comes into being in a simple body form. That form incorporates structural beauty, featuring bold design with delicate shadowing as well as black alumite-processed large heat sinks symmetrically located on the left and right sides of the housing. A sense of unity with Esoteric's high-end lineup is also projected, bringing about unrivaled presence when putting together an audio system.
