The noise is loud enough for my small set up. No lack of power for the way I had set it. It seems to be an amazing value. This unit has1 day of being used so far.

The rack ears do not fit! WARNING, you're going to spend over 2 hours drilling out the ears, filing metal burrs, sanding, masking and painting them and them maybe it'll fit in a standard rack but it still won't but go right ahead and try it yourself. If I had a machine shop at my house it would be possible but I don't. I loosened all my rack gear too and it still would not fit, even with slightly bending the sides of the rack inwards. Someone might say it's not a problem but it is a problem. Why should I or you have to go through all this aggravation, work and lost time. The amp install should have taken 5 minutes, that's it. BEWARE THE RACK EARS ARE NOT STANDARD SIZED FOR THE USA MARKET. UPDATE: I've decided to exchange the amp in the hope that the next one will fit. I'll update my review soon.

I have owned this for a few months now and I have no regrets about buying it but I found that it needs a hotter signal to get it to the wattage point so I added a nobsound direct e6 tube preamps which I personally use in my home theater setup because the class d amps need more analog input to give them a warm sound and not so harsh on the higher frequencies and midrange frequencies are a lot better imho so I use them in my entire system all 9.1.4 so I don’t use my Denon AVR amps at all and the sys 4500 fit my old school DCM tf350s speakers very well because they are a 88db speakers and they need power and the amp fits the need and with a good amount of power left to boot. I am not sure how much power they are using but I am not able to get the amp pass 12 o’clock and at reference volume I can’t listen to them at this volume very long. I bought this amplifier because my speakers were starving for power and boy it definitely feeds them and I wasn’t expecting this Musysic SYS 4500 to work as well as it does but it works . I don’t know if I got the better built amplifier or what but it works great. The tube preamps definitely help with the sound and I’m sure it wouldn’t be able to produce the same sound without them. My room is a partly open concept but I haven’t been able to get the sound that I wanted until now so I’m pleased with the amp and I thought I would hate the blue led lights but I never seen them light up other than the time I set it up and so far it’s been light free even at high impact moments. My speakers are around 28 to 35 hz which is the other reason I why I bought the amplifier because of its ability to reach high 50k according to the specs weather that is true or false I don’t know , what I do know is that my speakers are now awake and that’s what I have been searching for. Overall it is a very good amplifier and I have no complaints except the fans are a little loud and I may replace them if my rack stays in the room which I have been working on moving it to my garage. Finally thought about the amplifier i know that having a dedicated outlet would be a great idea and it wouldn’t have to suffer from lack of power , so buy one and you are not happy with it then you can return it. BIG PLUS in my book even though it’s not perfect.

Bought this used, in order to drive two 4x12 350W guitar cabinets, and it does, but just barely and not by much. The transistor in this amp really needs a pretty hot / powerful audio signal like a pre-amp driving the signal it in order to make these work out to be anywhere near loud. The rear fans are pretty loud if you cannot drowned them out with at least constant 50 Db. I bought a used unit, and the left front bracket arrived smashed and bashed in , and un-mountable. I had to put the bracket into a vise and straighten it out with a 3 lb hammer. This seems closer to a 400W max amplifier at 4 Ohms. The "2000W" rating is laughable.

The amplifier sounded reel good but the fan is very noisy when no music or sound is playing. If a more quiet fan would be replaced in the amp I would purchase the item again
