Every corner has been maintained, such as replacing 2 output relays, replacing 4 transistors, disassembling and polishing switches, etc. Upgraded model from AU-D607. The sharp punch is strong, and the sound with a sense of dynamism is superior to the α series. You can enjoy sharp and powerful sound. I recommend this car for people who like analog jazz, blues, etc. You can see a feeling of use such as appearance, dullness, scratches, etc. (Kobayashi Hitoshi)
