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.
- Additionally, there is NO current limiting and there is no protection circuitry in the amplifier circuit path. Even if the speakers' impedance drops to a low level, the Monolith is robust enough that the current is never limited.
- 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!
- With a more than 120dB signal to noise ratio, the Monolith 3 can clearly and accurately articulate the quietest portions, the loudest portions, and everything in between.
- Class AB: More efficient than Class A, many high end, audiophile grade amplifiers utilize a Class AB design.

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.

I bought the 2 channel version to accompany my Marantz SR7009 if I want to have a stereo session. I used Pangea 14se mk2 power cables for both this amplifier and my Marantz. This amplifier is heavy, you can see the toroidal transformer and a giant heat sink for each channel through the top peephole. Definitely a quality amplifier that is made (designed and assembled) in the USA. It is easily driving my Dynaudio dm3/7 which is a hard speaker to drive with 4ohm impedance, 86db sensitivity, and IEC power handling of >200W+. This unit does not get hot at all, even after hours of usage. This is definitely an audiophile quality amplifier. The power remote cable is convenient feature, it is connected to my Marantz so I don't have to keep turning both units on and off. I was comparing this to Schiit Vidar, I ended up returning my Schiit Vidar and I am not looking back. Update1: I swap my source to MacBook pro/ps audio gcd and this amp sings beautifully. This amp is only as good as the source that you put in. This is definitely an audiophile-grade amplifier. My reference is Luxman 550axii & McIntosh ma252. Update2 (3/2/2020): I have changed my setup to a near field desktop setup, I am using this amplifier with Sonus Faber Chameleon and Aune T1 with Siemens cca tube buffer. My Marantz SR7009 was the bottleneck as it could not deliver a higher resolution sound. I have finally found synergy with the above combination. Depending on what you are looking for in a sound as an "audiophile", this amplifier can deliver a sound resolution that matches 5x the price. I do not have a single regret buying this amplifier. Update 3 (5/19/2020): I just acquired magnepan 1.7i recently and two of my integrated amplifiers (mcintosh & luxman) did not seem to bring the 1.7i to life. I swapped it with monoprice and its sheer power brought my 1.7i to a whole new different level. I use schiit sys as preamp and htpc with evga nu audio pro installed as source.

Absolutely solid amp. The power up feature keeps it from flipping my breaker, and the trigger works perfectly with my Denon 3600H. This is a heavy class A/B amp and, from what I can tell, deserves the great reviews it has gotten. There can be a small squeal in the power supply if you have some noise on your power lines. I would recommend putting an isolater on its line if you encounter this. There is absolutely no hiss at all from this thing even with regular RCA cables bought here on Amazon. Would recommend going with the larger ones (5 or 7 channel), if you can afford it. The 2 channel is $1100 ($650 per channel) or you can get the 7 channel for $1500 (when Amazon has it at this price) which is $214 per channel. The larger ones are a much better value.

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.

This amp is heavy and tough. I have this paired up with my denon x4500h and noticed all my klipsch rp speakers have slight low hum if you put your ear right in front of the tweeter. I dont hear the hum when I sit in my sofa 12ft away so it doesnt bother me as much anymore. My denon reciever alone sounds a little more forward with slight more clarity with no hum and my monolith amp is a little less forward more natural sounding less in your face with wider sound stage with slight low hum. I was able to get mine for $1300 since with my applied amazon points to make it cheaper. The temperature is cool and warm to the touch so far and all 7 channels work for me. Just be prepared to by a power conditioner to eliminate hum and cleaner power with surge protection. I think that my denon reciever sounds a little better than my monolith amp imo but the monolith amp is no slouch at all. In terms of sound I would rate the monolith amp an 8 out of 10 and my denon av reciever a 9 out of 10 for sound. I know this amps will help my av reciever do less work but I just have to eliminate some electric line noise then it would be perfect. Perfect entry home theater amp for the value.

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.

So far mine is working perfectly powered by my Yamaha AVR as pre-processor using inexpensive but decent quality RCA cables. No hum whatsoever, trigger works just as it's supposed to without having to change any trigger related settings in the AVR. For me it's been a huge upgrade that has made my KEF LS50's come alive and sound much better than they did powered by the AVR. Oddly, even my SVS powered sub seems to sound better although I have no idea why since it is not getting any power from the Monolith. Probably just placebo effect, I suppose. I mainly listen at moderate volumes but even at modest volume there is obvious added detail, separation (imaging?), clarity, and sense of effortless power vs. the AVR alone that is much appreciated. Currently, only using 5 of the 7 channels and so far mine hasn't seemed to get too hot. (It's on the floor with nothing blocking air flow above it.) No problem holding my hand on it on the warmest parts of the top so don't think I will need to add a fan even here in Hawaii where the ambient temp can be pretty high. So overall I'm very pleased with it and highly recommend it.

This amp is a beast. It weighs a ton because it is a high quality amp. The 0.03% THD makes this a really nice sounding AB class amp. I had zero problems out of the box. I used XLR cables to connect to my Marantz surround processor and my dual SVS PB 4000 subwoofers. In some of the reviews people complained about ground loops (audio noise/hum). The best solution for that problem is a good quality line conditioner. The line conditioner also extends the life of your electronic equipment by preventing over/under currents. This amp is a steal for the money! I am totally satisfied.
