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. This 7025 has replaced a 17 year old Adcom power amp I retired from home theater duty. The Adcom seemed more powerful although its rated power was lower (no surprise), BUT the GFA 7000 was too cold and analytic in presentation.
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. The holes in the posts will not accept 8 or 10 gauge wire. I'm not sure about 12 gauge, but they will take 14.
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 explosive rumbles in the Dark Knight and the deepest notes of John Williams' symphony without effort.
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. It had a good sound, but ultimately I didn't believe that it would have enough power to drive my entire system by itself. Ultimately I had my old amp repaired and sent this one back, only because of the price.
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. Despite the power deficit, the Marantz sounds real nice with the 901's and seems to be stout enough for them.
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. The amp starts up a few seconds after the receiver is turned on.
Summary: Using Arcam DAC into Marantz AV7005 to the MM7025, which is then driving B&W PM1s. Replaced a Yamaha receiver with about the same power. The difference is stunning, even the wife, who never listens was immediately captivated. Depth, clarity, power all great. No hard edges to the sound like some other amps I looked at. Really woke up the PM1s.
Pros: Depth, clarity big improvement. Looks match the AV7005 and are nice. Used banana plugs for out and XLR balanced connections for in, which worked great.
