Review: Solid amplifier for the price - I bought this amplifier to power a modest 5.1-channel home theater system that is still a work in progress. The MM7055 5-channel amplifier is paired with the Marantz AV7005 preamplifier (now out of production and replaced by the AV7701), Klipsch Heresy III speakers and a Klipsch SW-110 subwoofer. This Marantz amplifier produces clean and powerful sound that fills my living room effortlessly. To extend the 5.1-channel theater experience, one or two MM7025 2-channel amps can be connected to accommodate 7.1-channel or 9.1-channel surround sound, respectively. The MM7055's continuous power output is rated 140 W per channel at 8 Ω (20 Hz to 20 kHZ with a THD of 0.08%), 2 channels driven. Frequency response is 8 Hz to 100 kHz (±3 dB) with a SNR of 105 dB. The amplifier measures 17.3 (W) x 7.2 (H) x 15.1 (D) in. and weighs 34.6 lbs. It carries a 3 year warranty for parts and labor. The MM7055 houses the same push-pull circuit used in some of Marantz's high-end amps such as the Reference SM-11S1. Furthermore, it offers the same high efficiency power transistor as the more expensive amplifiers, allowing for an enhanced supply of power. This Marantz utilizes also a large high-efficiency transformer. Collectively, these internal components allow the MM7055 to really shine and provide an instant, powerful audio range with minimal distortion. I find the sound to be lush with warmth and detail. The highs are delicately crisp and the bass responsively punchy. The sound stage that is created is impressively wide and deep yet natural, giving the stellar reproduction of a live concert performance. The MM7055 offers connections to a preamplifer with either XLR input connectors for balanced input or RCA input connectors for unbalanced input. I have set up XLR connections with my preamp. While turned on, the amplifier heats up quickly in my glass-enclosed media center cabinet. The built-in cooling fans run quiet and are barely audible; however, they do not do an adequate job dissipating the heat that is generated. I decided to purchase an external cooling system which prevents the amplifier from running too hot. The MM7055 is no longer made in Japan but rather in China. Other than these quibbles, I do not have any major complaints with this amplifier. The MM7055 is a highly recommended product that is an excellent value purchase.
Review: Vibrates - Never even plugged it in took it out of the box set it on my rack wasn’t going to hook it up for a few days. I’m waiting on my electrician to drop some wires. Had some music playing I was hearing this vibration couldn’t figure it out looked around and looked around. It’s the amp the cover on the amp, vibrating like crazy. 👎👎 looks like it probably took a pretty good beating during shipping that might have something to do with it. I don’t know, but if that’s the case, they should package it better… have another one on the way we’ll see if it vibrates or not. If so, I’ll be looking for a different brand.

## Questions & Answers

**Q: Can four of the channels be bridged into two for more power?**
A: No, This amplifier was not designed for bridging. Keep in mind, when you bridge an amplifier, you raise the noise floor, cut the amplifiers slew rate in half, and the amp looses control of the speaker cones. If you want High-Fidelity sound reproduction, you're not going to get it by bridging.

**Q: can mm7055 strong enough to drive KEF R205 speakers**
A: You will have more power than you know what to do list trust me an absolute great amplifier

**Q: I have marantz av7500 surround receiver, can I connect it with power amp?**
A: Yes you can. Just connect the mm7055 5 inputs to your marantz av7500 pre-outs and you will have your front, centre and rear channels connected. If you have an active subwoofer it should stay connected to the marantz av7500 subwoofer output.

**Q: How is volume control done for this amp ? I plan to connect my denon x3600h 3 channel pre out to this and my Yamaha rn603 stereo preout will it match?**
A: First thing gain has to match both units  usually it’s around 29 DB to find more information about gain go to YouTube search for Paul McGrown gain

### ⭐⭐⭐⭐⭐ Great amplifier!
*by T***Y on December 8, 2025*

This unit is Phenomenal! My comparison reference is the Emotiva XPA-2 (gen 3). The Emotiva is no slouch it is a solid amp. However, for the same price the Marantz MM7055 is better in multiple ways. 1. Aesthetics – look feel and build quality are far above. 2. Power- this amp is smoother and stronger. 3. This amp is five channels that can run my entire 5.1 system. Whereas Emotiva is only two channels for the same price. Also, less performance IMO. 4. It matched better with my Klipsch towers. The Emotiva tends to want to over-drive them. Whereas the Marantz gives them more precision and oomph. No distortion, just deep, clean and very precise. I highly recommend this amplifier. It is the best that I have ever owned. Price to performance is excellent!
