TEAC a-80 Guide De Spécification

 
 
 
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  μF / 76 mmφ  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.
