New Product Information
The new ESOTERIC A-80 monaural power amplifier provides
exceptionally high speaker driving ability applying rich power
supply in a compact size dimension. Cutting edge circuit design,
highly sophisticated architecture of components and precise
machining technology – incorporating these finest elements, the
A-80 delivers the ultimate musical expression to true musical
enthusiasts.
The high quality power supply
The A-80 features highly-rated (approx. 1k VA) large toroidal
transformer for main power supply, and R-core sub transformer is
added for further stability. The ultra stable and rapid power
supplying capability of A-80 is further enhanced by two large
capacitors (33,000
μ
F / 76 mm
φ
x 100 mm) used for the power
stage.
State-of-the-art component architecture
One of the most unique features of the A-80 is its state-of-the-art
component architecture.
The core components of the A-80 are assembled on the massive
9mm steel inner chassis, which is precisely machined from steel
block. The power supply components are suspended from the
bottom of the chassis to achieve the low center-of-gravity structure.
The amplification stage is attached on the top surface of the
chassis to isolate itself from potential vibration and magnetic flux
leakage from power supply components.
This extremely massive core chassis assembly is supported by
three stainless poles equipped with ESOTERIC’s proprietary
quenched steel pinpoint feet system. Total weight of this pole
mounted feet system amount to 2.7 kg, and directly supports the
core assembly with ultimate rigidity. Bottom surface of the pinpoint
feet cup is an arch-shape to allow minimum area “cup fringe”
contact to the floor.
