Summary: I purchased this amp directly from Marantz after researching numerous power options and reading many professional and owner reviews. I have owned quite a lot of electronics ranging from entry level to audiophile gear over the past 20+ years.
Summary: The speaker terminals accept banana plugs, but are not the standard 3/4 inch GR spacing, meaning that you have to either use single jacks or, as I did, use four dual jacks and only connectone post on each. If you want to connect your speaker wires directly, you may find other issues.
Consistent Sound Delivery but Limited on Features and Performance

Summary: Initial Thoughts This amplifier is absolutely incredible! This amp opened up the sound stage and provided incredible depth to music that I've never heard before. The spacial positioning of each instrument in an orchestra is crisp and distinct, the bass is authoritative and powerful, delivering...
Summary: Stereo separates are getting hard to come by these days, and Marantz certainly isn't what it used to be. However, when my power amplifier burned out and I needed a replacement, this particular component was one of the top contenders.
Summary: I have been using this amp with a Marantz NR1602 receiver to drive my Bose 901 VI loudspeakers. It does this quite well. Previously, I used an Adcom GFA5500, which is a much heavier amp, rated 200W per channel into 8 Ohms and 350W / channel into 4 Ohms compared to the Marantz's 140/170 Watt ratings.
Pros: Beautiful looks! (If you appreciate such things!) Quiet operation Neutral sound Manageable size Fair price Good power
Cons: Not rated for 4 Ohm loads Auto power off circuit could be improved by including a signal-sensing function.
Summary: I got this to use for the left & right main channels of my Marantz SR7005 receiver. I'm very happy with the results. I think the MM7025 does a better job driving the B&W 604 speakers. The remote control connection to the reciever is nice.
Summary: I purchased a pair of these for a project i am doing, but in the mean time i am using them to bi-amp a pair of Martin Logan SL3s. They have a great sound and are easily running the power hungry electrostats, though I am not pushing them hard as the speakers can drop impedence loads when pushed.
Pros: Marantz sound, powerful and rich. Balanced and unbalanced inputs available for flexibility of connections. Matches my existing Marantz receiver with the porthole design.
Cons: Not stated as 2 ohm stable. Of 2 ordered one was doa.
