Audiophile quality Acoustic Research AR components – system sounds great – very powerful. I pieced this system together over the years and it includes 6 components + remote. A-04 Integrated Amplifier (works great). T-04 Tuner (works great). CD-04 CD Player (works but some lights are out). X-06 Receiver Amplifier (works great). CD-06 CD Player (works with some lights out). RD-06 Cassette Deck (works great – new belt). RC-02 Remote Control (new in box).
