Features

  • Power: A true 200-watt experience. Unlike most amplifiers or receivers, the Monolith's 200 watts per channel rating is measured with all seven channels driven across the full power bandwidth of 20Hz to 20kHz into 8-ohm loads
  • Dynamics: High resolution audio delivers the best in music and movie soundtracks. You deserve an amplifier capable of delivering clear and clean audio across a wide dynamic range!
  • More than 120dB signal to noise ratio, the Monolith 7X can clearly and accurately articulate the quietest portions, the loudest portions, and everything in between.
  • Clarity: More efficient than Class A, many high end, audiophile grade amplifiers utilize a Class AB design.
  • Silent Cooling:Oversized heat sinks, instead of fans, are used to keep the amplifier as cool and as silent as possible

  • Great quality amplifier for a great price
Size: 7 Ch.
The amplifier offers great quality for a great price. Extremely low distortion Class AB 7 channel solid-state amplifier. I has to massive toroidal transformers the unlike may other the circuit board an wiring is clean and well organized. It is well passively cooled as long as you leave proper airspace around it. The only down side is it weighs a lot, probably to heavy for most in wall rack mounts but fine for most floor standing av shelfs. you may need a second person to help you lift out of the box and on to a shelf. As far as people saying that the amplifier has a low hum distortion. They probably have a ground loop hum. It can caused by many things. I had one originally it traced it to my tv coax cable connecting to my cable box the ground loop was being carried from the coax line to my cable box and carried over to my receiver and then to my amplifier causing the hum on my speakers. I fixed it by putting a ground loop filter between my coax line and my cable box. Another step you can take to prevent ground loop hums it to run a ground wire from the ground terminal screw on the amp to the ground terminal screw on your receiver or preamp. The amp sounds great and has a lot of power, I originally was running MA700 Marantz mono block amps rated at 200 watts rms but even though the monolith amp is rated at 200 watts rms per channel as well i had to lower my volume by 10 -15 db as was much louder at the same volume level, too loud like it hurt my ears loud at the same volume level, and this is coming from some one who plays their movies in their home theater loud, usually get asked by other viewing with me to turn it down some. ... show more

  • Solid performer so far
Size: 5 Ch.
I doubt this will be brief.... Started with a Yamaha 3050, which was the first receiver I've ever had with a dead silent background (no static hiss coming from the speakers) and what felt like "high-end" sound quality, along with my Atlantic Technology 350 speakers up front (2200s everywhere else). However, the 350s started to die so I went in search of other, equivalent speakers and decided on the M&K S-150s. Since they're power hungry I knew I needed another, stronger amplifer than what was in the receiver, so I picked up an Emotiva XPA-5 2nd Gen. The match-up of the Emotiva and the M&Ks gave a super punchy, impactful sound with a much, MUCH tighter mid-range than before. There was, however.... a hiss. A hiss had started to come out of my speakers again. It was definitely the Emotiva doing it. The treble was also a lot less clear but it hard for me to discern whether or not that was the speakers or the amp doing it since I swapped both at the same time. But certain movies that I really enjoyed watching at high volume became grating to the ears (Fury Road and The 5th Element.) But that there was a hiss, and one that was definitely coming from the tweeter(s). Very disappointing. So I either needed new speakers or another amplifier, but which to upgrade first?--I'm not made of cash! The only speakers I'd want to upgrade to would cost $3,000+, and I thought about jumping straight to an Outlaw Balanced amp, but they recently raised their prices, so I decided on the 5 channel Monoprice Monolith (with the XLR inputs). THE RESULTS: so far I am super impressed. Not only do I have my dead silent background again but everything sounds clearer and even more impactful than before. I ran through the movies that had been driving me crazy and they definitely less grating on the ears. For a minute I thought dynamics might be lacking, then I'd get punched in the chest. Watching Isle of Dogs for example (did not expect it to impress on the sound front), the various drum sequences had surprising power and slam coming through the speakers (did not seem to be coming from the subs--my subs aren't that fast.) It's hard for me to comment on the treble. It's definitely better than the Emotiva, but I don't know if it's as good as my Yamaha/350 combo. I threw the 350s back into the loop straight from the Yamaha and was blessed with this enormous, enveloping, silky sound bubble that I had missed for so long... but that was about all that was good with the sound. With the Monolith/150s, it's more like a sterile, laser-shot of sound right at you. Much like I had with the Emotiva/150s but slightly cleaner, smoother, and punchy. Also, it seems to me that both Emotiva and Monoprice owners sometimes complain about a hiss. The Emotiva I got was even straight from the factory (it had been refurbished). I have this theory that those hisses aren't within what either company would consider "failing" performance. Whether or not that slight hiss is something that amplifies with the signal and noticeably degrades the sound quality is another matter. However, so far the Monoprice definitely seems like an upgrade from the Emotiva, but then again it was a Gen 2 and not the new Gen 3. I'm extremely pleased thus far ... show more

  • Great option to drive 4-ohm front speakers.
Size: 3 Ch.
I bought the 3-channel version to drive the 4-ohm THX-ultra main LCR speakers for my home theater project. It does exactly what it should: delivers clean, distortion free power at reference volume levels. An AVR’s class D amplification can be great for 8-ohm loads and surround channels, but just isn’t up to the task of driving 4-ohm loads at the power levels needed for front speakers. This class A-B amp has headroom to spare, powers on and off without any trace of thump or pop, and does its job for hours on end without breaking a sweat. After a recent 10-hour movie marathon, this amp was barely warm to the touch, a testament to the importance of construction and mass (about 70 pounds.) Although not a cheap solution, this amp is a good value compared to its peer class A-B amps of this caliber. In my setup, the Audessey calibration showed only a -2db volume adjustment was needed for the fronts using this amp, so the reference level of amplification was perfectly matched for my application. If you’re building a home theater, don’t scrimp on the power source for your main speakers. Adequate power makes all the difference to the experience of your theater, and the performance and longevity of your speakers. ... show more

  • Humming right along and then it died
Size: 11 Ch.
I rate this amplifier quite highly for its performance. If it didn't have a hum from the left channel I would rate it 5 stars. For full disclosure, I contacted Monoprice on 12/19/2022 and they will replace the unit but the expected date to have replacements is December 5, 2023. I'm not certain why they won't have me return it for repair. Only replacement. Now on February 2, 2023 the right channel quit working. I can't return it through Amazon and the manufacturer has no replacement. Pretty awful if you ask me. I’m left holding a100 pound paper weight that cost me more than $2,400. ... show more
