Full product details
The new MM7055 is the five-channel option in this year’s extended line-up of main amplifiers. Based on the technology used in the MM8003 and using the exact same chassis, it delivers a thumping 140W rms into 8 ohm to each of the channels, while the ultra-wide bandwidth current feedback technology easily handles the highest SACD frequencies – this also makes it ideal for the high definition DTS Master Audio and Dolby TrueHD formats too. The result? Totally precise tonal and image balance, speed and dynamics. And on top of all that, you also get XLR audio inputs, DC triggers and a Marantz control bus system for remote on/off. There’s even a stylish new display screen showing the actual output power. This is power and convenience to take your breath away.
