XA8550 power amplifier is designed especially for matching with XA3250 pre-amplifier. It is with high fidelity for reproduction the music signal. The appearance is both simple and elegant. The inner circuit design derives from reputable current negative feedback circuit of XA6950 and adopts Darlington structure on the current amplifier stage. The output power dynatrons are three pairs SANKEN 2SC3264/2SA1295 whose peak current can reach 51A, to insure the driving power. The filter capacitor for main power supply is 82000uF/63V Rubycon capacitor, and the power supply is two 300W annular transformers. The tone is balanced and neutral, with good speed sense and analysis ability.

In addition, there are two editions for XA8550 as optional, one is XA8550T and the other is XA8550S, which with different case design with each other.
