Receiver is basically a preamp and amp in one. This is just the amp. People buy it so they can dedicate the receiver to just process the signal and let these beefy amps do the heavy lifting. In 95% of cases, the receiver alone will be just fine.
Thiss is mainly for enthusiasts who wants to give a little more power to their speakers.

These are great amps, but please be aware of Monoprice's B stock policy. It's a like-for-like exchange on these amps. Should you need warranty service on your amp, you can return it, and they will send you another B stock unit, if they have any in stock. If they are out of stock, you can return it for a refund or wait for a B stock unit to come back into stock. This isn't very well explained on their website, but was clarified when some of the AVS members asked for clarification back when these were available last November.

Not necessarily unless...

1. If you have very efficient speakers and you hear hissing noise (the noise floor on the 555 is higher) because of it, switching to Monoliths will make it quiet.

2. If your Adcom is getting too old and has never been refurbished, and so its capacitors are starting to leak or stray from their ratings, the sound may not be as good as when you bought them. Switching to any new amp let alone Monoliths will fix that.

The Monolith will have a slightly brighter sound than the Adcom whose JFETs roll off higher frequencies a bit compared to the Monoliths which have a clean, flat response in audible range. This may sound better or worse depending on one's taste, tolerance for higher frequencies, etc. Adcoms sound warmer because of that.

These are class AB amps, expensive, but the real deal.
Pretty much any consumer amp in this price bracket is class A/B.

Are you trolling or confused? These are power amplifiers, not receivers, preamps, or processors. They have nothing to do with video or source switching.
What do you need to use this for a home theater? Processor? Receiver?

Are these hiss \ hum free amps? The outlaw and OSD are class AB amps and they seems to both have hissing or hum problems.

Wouldn't a processor be a better fit? Amp part of a receiver would not be used when paired with this amp

Can I use this with sonos connect:amp? Whenever I turn up the volume I loose connection to sonos. Could it be I'm overloading it?

I have a denon x4400h. Is this going to make a big different? I do have a set of klipsch rf7 ii that could use the extra power.

Good deal! I bought Outlaw Audio 7x120w amp last month for $1100. I used Klipsch speakers so that's more than enough, but I probably would lean toward buying one if this deal came up earlier.

You could use a dedicated processor to switch inputs and process/decode video and audio. The audio output from the processor is sent to a power amplifier like these, which in turn power speakers. Processors tend to be expensive (Anthem for example) and most newer receivers are almost as good at s fraction of the price.

Many AV receivers support more channels than they have built in amplifiers for. These amps can be used to power those additional channels. If the receiver has preamps outputs, you can bypass the internal amps and use a dedicated amp like these with more and/or cleaner power.

The ratings you're referring to are for speaker impedance, similar to resistance. Speakers with lower impedance tend to draw more current. The impedance is a function of the speaker driver design. For example, when you find a pair of speakers you like, you're stuck with whatever impedance they have. There are no choices when it comes to impedance for a particular speaker. Amplifiers rated for 8ohms usually can't handle 4 or 2 ohm speakers.

Class A is very linear, but also the least efficient and most expensive amp design.

I don't think there is a Class B for audio.

Class A/B is not as linear as Class A, but it's more efficient and costs less.

Many current receivers use Class D, which are very efficient and cheap and if done right, sound great.
