The perfect partner for the AV8003, the new Marantz MM8003 is the ultimate-quality audio and video entertainment hub. The MM8003 has a massive high-current, audiophile-grade, oversized toroidal power transformer, which delivers a conservatively estimated 150 Watts to each of the eight channels. This works alongside custom filter capacitors, high grade audio components throughout, extensive shielding of key components, and ultra-wide bandwidth current feedback technology. The latter amplification system was originally developed for Super Audio CD signals and is ideal for the new DTS-HD Master Audio and Dolby True HD formats. The result of all this technology is an unerringly accurate tonal and image balance, allied to speed and dynamics with very low distortion. Combining with this great sound is outstanding flexibility, such as eight channels, balanced input terminals, output channel relay on/off control and a slow start to power-on function. The MM8003 is built on a rigid full metal chassis which virtually eliminates any sound degrading vibration. Again, this is completely copper-plated delivering perfect grounding and guards against electrical interference.
