The A800 is one of the Class A headphone amplifiers with small size,it uses the transistors made up of the discrete components .The circuit structure uses the simplified Class A OTL amplifier .With the paired transistors selected by the signal transistor graphic instrument,and the cooperation of the tuning team by Yulong Audio,the small and exquisite A800 has the fascinating tone and the good driving capability.
The A800 has a small size(160*110*30mm),the shell of the A800 uses the aluminium alloy made carefully,it looks exquisite and it weighs only 0.4kg.The size of the A800 is the same as the U100.It can be matched with the U100 as the upgraded headphone.
The A800 uses the external high-quality global AC power supply(90V-270V,50/60HZ).
Note：A800 is a Class A amplification, using the electric machine through 3 minutes, until the temperature rises, only the best sound
