Recently, some customers reported that AIYIMA A03 with tpa3156 chip instead of tpa3116 amplifier chip. So we checked our current domestic inventory, and indeed there are the same problems. During this time we have been looking for the cause of this problem.

Some customers Feekback that the power of the TPA3116 chip of A03 is not enough, so we adopt TPA3156 to upgrade A03.

Recently, a customer customized A03 with TPA3116 chip. However, our warehouse accidentally mixed the A03 with TPA3156 and this customer-made A03 with TPA3116 when they are packing . So there is a phenomenon that A03 power amplifier has both chips TPA3156 and TPA3116.

At present, our company's domestic warehouse inventory is TPA3156, but the Russian warehouse and German warehouse have both TPA3116 chips and TPA3156 chips.

TPA3156 is functionally ahead of TPA3116.
Panasonic's ECQV1H684 laminated layer cake film capacitor, excellent performance, Japanese power amplifier, decoders are very common, the actual hearing is no different from EVOX 684 (Evox Rifa has been acquired by KEMET).
Nichicon 25v6800uF VZ is a standard product, while CapXon's 25v5600uf and PH series belong to Low impedance and high ripple current, and the capacity difference is 1200UF and the filtering effect is comparable.

As for this case , if you mind receiving upgraded A03 with TPA3156 chip when you choose buy from Russia and Germany , please contact us in time, we will give you a $10 coupon or refund, and you can buy TPA3116 chip to replaceit by yourself.
